Double-blind intervention trial on modulation of ozone effects on pulmonary function by antioxidant supplements. (1/1280)

The aim of this study was to investigate whether the acute effects of ozone on lung function could be modulated by antioxidant vitamin supplementation in a placebo-controlled study. Lung function was measured in Dutch bicyclists (n = 38) before and after each training session on a number of occasions (n = 380) during the summer of 1996. The vitamin group (n = 20) received 100 mg of vitamin E and 500 mg of vitamin C daily for 15 weeks. The average ozone concentration during exercise was 77 microg/m3 (range, 14-186 microg/m3). After exclusion of subjects with insufficient compliance from the analysis, a difference in ozone exposure of 100 microg/m3 decreased forced expiratory volume in 1 second (FEV1) 95 ml (95% confidence interval (CI) -265 to -53) in the placebo group and 1 ml (95% CI -94 to 132) in the vitamin group; for forced vital capacity, the change was -125 ml (95% CI -384 to -36) in the placebo group and -42 ml (95% CI -130 to 35) in the vitamin group. The differences in ozone effect on lung function between the groups were statistically significant. The results suggest that supplementation with the antioxidant vitamins C and E confers partial protection against the acute effects of ozone on FEV1 and forced vital capacity in cyclists.  (+info)

Enrichment of enzyme activity on deformylation of 1-NFK-lysozyme. (2/1280)

The formamide linkage of an inactive lysozyme derivative (1-NFK-lysozyme), formed by selective ozonization of tryptophan 62 in hen egg-white lysozyme [EC] was hydrolyzed with dilute acid faster in the frozen state at about --10 degrees than at 20 degrees. On hydrolysis of 1-NFK-lysozyme the low lytic activity increased to approximately 80% of that of native lysozyme. It is suggested that the binding ability associated with kynurenine 62 in the lysozyme derivative formed by this hydrolysis may be responsible for increase in enzymatic activity.  (+info)

Airway inflammatory response to ozone in subjects with different asthma severity. (3/1280)

The aim of this study was to evaluate whether ozone exposure induces a similar airway inflammatory response in subjects with different degrees of asthma severity. Two groups of asthmatic subjects were studied: seven with intermittent mild asthma not requiring regular treatment (group A); and seven with persistent mild asthma requiring regular treatment with inhaled corticosteroids and long-acting beta2-agonists (group B). All subjects were exposed, in a randomized cross-over design, to air or O3 (0.26 parts per million (ppm) for 2 h with intermittent exercise); subjects in group B withdrew from regular treatment 72 h before each exposure. Before the exposure, and 1 and 2 h after the beginning of the exposure they performed a pulmonary function test, and a questionnaire was completed to obtain a total symptom score (TSS). Six hours after the end of the exposure, hypertonic saline (HS) sputum induction was conducted. Sputum cell percentages, eosinophil cationic protein (ECP) and interleukin (IL)-8 concentrations in the sputum supernatant were measured. TSS significantly increased and forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) significantly decreased after O3 exposure in comparison with air exposure in group A, whereas no changes were observed in group B except for a significant decrement of FEV1 2 h after the beginning of O3 exposure. Sputum neutrophil percentage was significantly higher after O3 exposure than after air exposure in both groups (Group A: 70.2% (28-87) versus 26.6% (8.6-73.2); Group B: 62.1% (25-82.4) versus 27.9% (14.4-54)). IL-8 was higher in sputum supernatant collected 6 h after O3 exposure than after air, only in group A. No change due to O3 has been found in sputum eosinophil percentage and ECP concentration in both groups. In conclusion, the degree of airway response to a short-term exposure to ozone is different in subjects with asthma of different severity. The available data do not allow elucidation of whether this difference depends on the severity of the disease or on the regular anti-inflammatory treatment.  (+info)

Capsaicin-sensitive C-fiber-mediated protective responses in ozone inhalation in rats. (4/1280)

To assess the role of lung sensory C fibers during and after inhalation of 1 part/million ozone for 8 h, we compared breathing pattern responses and epithelial injury-inflammation-repair in rats depleted of C fibers by systemic administration of capsaicin as neonates and in vehicle-treated control animals. Capsaicin-treated rats did not develop ozone-induced rapid, shallow breathing. Capsaicin-treated rats showed more severe necrosis in the nasal cavity and greater inflammation throughout the respiratory tract than did control rats exposed to ozone. Incorporation of 5-bromo-2'-deoxyuridine (a marker of DNA synthesis associated with proliferation) into terminal bronchiolar epithelial cells was not significantly affected by capsaicin treatment in rats exposed to ozone. However, when normalized to the degree of epithelial necrosis present in each rat studied, there was less 5-bromo-2'-deoxyuridine labeling in the terminal bronchioles of capsaicin-treated rats. These observations suggest that the ozone-induced release of neuropeptides does not measurably contribute to airway inflammation but may play a role in modulating basal and reparative airway epithelial cell proliferation.  (+info)

Air pollution, pollens, and daily admissions for asthma in London 1987-92. (5/1280)

BACKGROUND: A study was undertaken to investigate the relationship between daily hospital admissions for asthma and air pollution in London in 1987-92 and the possible confounding and modifying effects of airborne pollen. METHODS: For all ages together and the age groups 0-14, 15-64 and 65+ years, Poisson regression was used to estimate the relative risk of daily asthma admissions associated with changes in ozone, sulphur dioxide, nitrogen dioxide and particles (black smoke), controlling for time trends, seasonal factors, calendar effects, influenza epidemics, temperature, humidity, and autocorrelation. Independent effects of individual pollutants and interactions with aeroallergens were explored using two pollutant models and models including pollen counts (grass, oak and birch). RESULTS: In all-year analyses ozone was significantly associated with admissions in the 15-64 age group (10 ppb eight hour ozone, 3.93% increase), nitrogen dioxide in the 0-14 and 65+ age groups (10 ppb 24 hour nitrogen dioxide, 1.25% and 2.96%, respectively), sulphur dioxide in the 0-14 age group (10 micrograms/m3 24 hour sulphur dioxide, 1.64%), and black smoke in the 65% age group (10 micrograms/m3 black smoke, 5.60%). Significant seasonal differences were observed for ozone in the 0-14 and 15-64 age groups, and in the 0-14 age group there were negative associations with ozone in the cool season. In general, cumulative lags of up to three days tended to show stronger and more significant effects than single day lags. In two-pollutant models these associations were most robust for ozone and least for nitrogen dioxide. There was no evidence that the associations with air pollutants were due to confounding by any of the pollens, and little evidence of an interaction between pollens and pollution except for synergism of sulphur dioxide and grass pollen in children (p < 0.01). CONCLUSIONS: Ozone, sulphur dioxide, nitrogen dioxide, and particles were all found to have significant associations with daily hospital admissions for asthma, but there was a lack of consistency across the age groups in the specific pollutant. These associations were not explained by confounding by airborne pollens nor was there convincing evidence that the effects of air pollutants and airborne pollens interact in causing hospital admissions for asthma.  (+info)

Effect of insurance coverage on the relationship between asthma hospitalizations and exposure to air pollution. (6/1280)

OBJECTIVE: Based on the assumption that people without health insurance have limited access to the primary care services needed to prevent unnecessary hospitalizations for asthma, the authors hypothesized that insurance is a factor in the strength of the association between hospital admissions for asthma and exposure to air pollution. They tested this hypothesis with 1991-1994 data from central Los Angeles. METHODS: The authors analyzed the effect of insurance status on the association between asthma-related hospital admissions and exposure to atmospheric particulates (PM10) and ozone (O3) using hospital discharge and air quality data for 1991-1994 for central Los Angeles. They used regression techniques with weighted moving averages (simulating distributed lag structures) to measure the effects of exposure on overall hospital admissions, admissions of uninsured patients, admissions for which MediCal (California Medicaid) was the primary payer, and admissions for which the primary payer was another government or private health insurance program. RESULTS: No associations were found between asthma admissions and O3 exposure. An estimated increase from 1991 to 1994 of 50 micrograms per cubic meter in PM10 concentrations averaged over eight days was associated with an increase of 21.0% in the number of asthma admissions. An even stronger increase--27.4%--was noted among MediCal asthma admissions. CONCLUSIONS: The authors conclude that low family income, as indicated by MediCal coverage, is a better predictor of asthma exacerbations associated with air pollution than lack of insurance and, by implication, a better predictor of insufficient access to primary care.  (+info)

Public health consequences of global climate change in the United States--some regions may suffer disproportionately. (7/1280)

Current risk assessments of the likely regional health impacts of global climate change (GCC) are hindered by two factors. First, dose-response relationships between weather parameters and many of the likely health effects have not been developed, and second, reliable estimates of future regional climates across the United States are still beyond the scope of current modeling efforts. Consequently, probabilistic risk estimates of most of the likely regional health impacts of GCC have such a high degree of uncertainty that their usefulness to health officials dealing with regional issues is very limited. With the numerous pressures on today's health care systems, it is understandable that the possible consequences of GCC have received scant attention from regional health care decision makers. Indeed, the consensus among this community appears to be that any increases in health effects associated with GCC will be easily handled by the current health care system. However, such a position may be naive as the potential exists that an unequal distribution of such effects could overwhelm some regions, whereas others may feel little or no impact. This review of the likely regional impacts of GCC has been structured as a semianalytical look at this issue of distributional effects. Because of the lack of dose-response information and reliable estimates of future regional climates, however, it takes a historical perspective. That is, it assumes that the quality and quantity of health risks a region faces under GCC will be directly related to its recent history of health risks from warm weather/climate-related diseases as well as to the size, characteristics, and distribution of the sensitive subpopulations currently residing within its borders. The approach is semiquantitative; however, it uses national data gathered on a regional level and as such should only be used to generate a hypothesis rather than test it. When applied to the United States, its outcome leads to the hypothesis that if indeed history repeats itself, some states or regions may be more greatly affected by GCC than others, not only because historically they are more prone to summer weather/climate-related diseases, but also because they contain a greater proportion of the sensitive subpopulations in the United States.  (+info)

Drinking water disinfection byproducts: review and approach to toxicity evaluation. (8/1280)

There is widespread potential for human exposure to disinfection byproducts (DBPs) in drinking water because everyone drinks, bathes, cooks, and cleans with water. The need for clean and safe water led the U.S. Congress to pass the Safe Drinking Water Act more than 20 years ago in 1974. In 1976, chloroform, a trihalomethane (THM) and a principal DBP, was shown to be carcinogenic in rodents. This prompted the U.S. Environmental Protection Agency (U.S. EPA) in 1979 to develop a drinking water rule that would provide guidance on the levels of THMs allowed in drinking water. Further concern was raised by epidemiology studies suggesting a weak association between the consumption of chlorinated drinking water and the occurrence of bladder, colon, and rectal cancer. In 1992 the U.S. EPA initiated a negotiated rulemaking to evaluate the need for additional controls for microbial pathogens and DBPs. The goal was to develop an approach that would reduce the level of exposure from disinfectants and DBPs without undermining the control of microbial pathogens. The product of these deliberations was a proposed stage 1 DBP rule. It was agreed that additional information was necessary on how to optimize the use of disinfectants while maintaining control of pathogens before further controls to reduce exposure beyond stage 1 were warranted. In response to this need, the U.S. EPA developed a 5-year research plan to support the development of the longer term rules to control microbial pathogens and DBPs. A considerable body of toxicologic data has been developed on DBPs that occur in the drinking water, but the main emphasis has been on THMs. Given the complexity of the problem and the need for additional data to support the drinking water DBP rules, the U.S. EPA, the National Institute of Environmental Health Sciences, and the U.S. Army are working together to develop a comprehensive biologic and mechanistic DBP database. Selected DBPs will be tested using 2-year toxicity and carcinogenicity studies in standard rodent models; transgenic mouse models and small fish models; in vitro mechanistic and toxicokinetic studies; and reproductive, immunotoxicity, and developmental studies. The goal is to create a toxicity database that reflects a wide range of DBPs resulting from different disinfection practices. This paper describes the approach developed by these agencies to provide the information needed to make scientifically based regulatory decisions.  (+info)

Although the effects of elevated ozone on aboveground carbon (C) assimilation are well understood, its effects on soil C fluxes are less certain. Mesocosms taken from a lowland raised bog in northern England were exposed in open-top chambers for 2 years to ambient air or ambient air plus ozone elevated for 8 h day−1 by an average of 49 ppb in summer and 10 ppb in winter. The effects of elevated ozone on methane emission and ecosystem dark respiration were measured throughout this period, along with soil and plant variables. Methane emissions were significantly reduced, by about 25%, by elevated ozone during midsummer periods of both years, but no significant effect of ozone was found during the winter periods. Dark ecosystem respiration was not significantly affected by elevated ozone. There was no evidence that effects of elevated ozone on methane emissions were mediated through changes in aboveground plant biomass or soil water dissolved organic C concentrations. Our results imply that the ...
Ozone therapy involves the administration of ozone gas into the body. This is done to help treat wounds and also in the treatment of diseases. Ozone is a gas that does not have any color and is used by doctors to treat different medical problems. This gas, once administered into the body, helps by disinfecting and treating various diseases. The most important benefit to using ozone therapy is it helps to fuel the immune system. When used in hospitals, the ozone gas is sourced from medical-grade oxygen sources. How does it work? Ozone therapy does its work by causing an interruption in the unhealthy conditions in the human body. One of the benefits it provides is that of stopping the proliferation of harmful bacteria. Ozone therapy also helps to prevent infections in the body from spreading. In fact, it has also proved to be effective in the treatment of infections caused by bacteria, viruses, fungi, yeast and protozoa. Once injected into the body, ozone gas helps to remove infected cells. When these
Another significant benefit of ozone therapy in dentistry is for root canal therapy. Ozone therapy is used to clean the site of the root canal before filling the space. By removing as much of the bacteria as possible, we prepare the mouth as best we can for a rapid recovery with the minimum risk of infection.. Given the speed and voracity of bacteria growth, any help we can provide the body in fighting bacteria can have long-lasting health benefits.. Ozone therapy can also be used for preventive treatment, such as when adult teeth appear in children or to help cleaning fissures before applying dental sealant. Other applications will no doubt be developed as ozone therapy matures and evolves as such treatments do.. If you think you may benefit from ozone therapy or would like to know more about its advantages, contact Aesthetic Family Dentistry today to schedule a consultation.. ...
What is Ozone Therapy?. Ozone is a natural gas that forms in the atmosphere and serves as a vital filter and barrier to ultraviolet solar rays. Did you know that Ozone also has medicinal uses? Whereas the oxygen we breathe is 2 combined oxygen molecules (O2), Ozone is 3 combined oxygen molecules (O3).. Medicinal Ozone therapy utilizes an Ozone generator to create a mixture of Oxygen and Ozone. The Ozone Generator creates Ozone by passing pure oxygen through a high-voltage, high-frequency electrical discharge. This electrochemical reaction produces a gas mixture with concentrated Ozone. The concentrated ozone and dosages used are adjusted and individualized to the pathology, patient, and the desired treatment.. The Ozone, when in contact with the organism, produces very important therapeutic chemical changes. It is widely used as an adjuvant medical treatment in a wide range of diseases. It is also used as an anti-aging strategy, to improve athletes performance and to gain wellness and quality ...
The main goal of the conventional periodontal therapy is to control infection and thereby curb disease progression. The mechanical removal of the oral biofilm and adjunctive use of antimicrobial agents have been the conventional methods for periodontal therapy. However, no consensus has been reached on whether conventional periodontal therapy can eliminate periodontal pathogens.1,2,3 It has been known that medical ozone therapy eliminated 260 different pathogens. Thus, applications of medical ozone may provide a potential benefit in the treatment of periodontal diseases by reducing and eradicating subgingival periodontopathogenic species in inaccessible sites.4,5,6,7,8,9,10,11. Applications of medical ozone are a new treatment modality that has been developing rapidly within various medical specialties since the 1930s. In 1933, Dr. E.A. Fish, first used ozone on a regular basis in his dental practice, and published numerous papers on the subject.4,8 Ozone (O3) is a triatomic molecule, consisting ...
We all the time advocate chatting with a health care provider with ozone expertise to determine how you need to use ozone and why. We can not provide specific dosages and occasions, however these are some of the ways individuals are at the moment utilizing ozone.. Drinking Ozonated Water: Utilizing an oxygen source and an ozone generator, you bubble ozone right into a water bubbler that has an ozone destruct system to maintain ozone from escaping freely into the room. The bubbler has an additional airtight silicon stopper that makes it simple to store water.. Breathing Ozone: You dont want to breathe ozone directly because it may be harsh and make you cough. By bubbling it by oil first, the ozone is much simpler to breathe. You want an oxygen supply, ozone generator and an oil bubbler.. Insufflating Ozone: Ozone may be insufflated a number of ways but of the preferred strategies contain an oxygen source, ozone generator, ozone humidifier and either an earscope or rectal catheter..

Increased UV-B through stratospheric ozone depletion leads to an increased chemical activity in the lower atmosphere (the troposphere). The effect of stratospheric ozone depletion on tropospheric ozone is small (though significant) compared to the ozone generated anthropogenically in areas already experiencing air pollution. Modeling and experimental studies suggest that the impacts of stratospheric ozone depletion on tropospheric ozone are different at different altitudes and for different chemical regimes. As a result the increase in ozone due to stratospheric ozone depletion may be greater in polluted regions. Attributable effects on concentrations are expected only in regions where local emissions make minor contributions. The vertical distribution of NOx (NO + NO2), the emission of volatile organic compounds and the abundance of water vapor, are important influencing factors. The long-term nature of stratospheric ozone depletion means that even a small increase in tropospheric ozone ...
Ozone or O3 is a highly charged oxygen molecule with increased oxygenating properties. It has been around for over 150 years used to treat infections. wounds and multiple diseases.. With higher levels of oxygen in the tissue, bacteria and viruses and defective tissue cells are killed. The healthy cells are stimulated and multiply more rapidly.. Ozone therapies are thought to benefit patients by stimulating white blood cell production, killing viruses, improving oxygenation, helping the body to fight infections and cancers, stimulating the bodys metabolism.. In Germany, ozone therapy has been widely used since the late 1950s. It is widely used by doctors and practitioners as a treatment for a wide range of degenerative conditions including cardio-vascular disease, diabetes, liver, and kidney disease. In 1931, the Biochemist Otto Warburg was granted the Nobel Prize for discovering that anaerobic cancer cells die in oxygen. This makes ozone therapy an extremely important modality in the treatment ...

In recent years, ozone therapy as an effective therapeutic method has become more developed and well known. Russia and Cuba have recognized it in their legislation; it is regulated in more than 76% of the Autonomous Regions of Spain; and in Italy four Regions have specified the criteria for practicing it, in addition to two favorable court decisions. Ozone therapy is characterized by the simplicity of its application, its great effectiveness, good tolerance, and by the virtual absence of side effects. This document, based on the latest books and scientific articles on the subject, updates the recent findings that justify, from the scientific point of view, the medical use of ozone. For many years the application of ozone in medical practice was not well accepted due to unfounded ideas about its toxicity in relation to the high concentrations used in industry. As with any healing technique, ozone therapy is dependent on the dosage. It is important to understand that in clinical practice the ...
Two different morphotypes of peas (Pisum sativum L.), the leafy form Ilgiai and the subleafy form Profi, were examined under ozone exposure. A day after exposure, adverse effects of ozone on Ilgiai morphometric features were observed, while certain processes in Profi were stimulated. After three days of exposure, the leaf area of leafy peas was reduced by 34%, while in subleafy peas it increased by 33% under the 160 μg m-3 ozone level. Chlorophyll and carotenoid content in leaves of leafy peas decreased with increasing exposition time and ozone concentration. However, a linear dependence between the content of photosynthetic pigments in leaves of subleafy peas and exposition time / ozone concentration was determined, and only the highest ozone level significantly decreased the content of those pigments. The ratio of hexoses to sucrose increased in leafy peas after one day of ozone exposure, but it tendentiously decreased as the time of exposure increased. The same trends were observed ...
Its on everyones lips, especially during the summer months when photochemical smog engulfs the worlds cities. Environmental pollution and climate change both contribute to the increasingly frequent incidences observed. While this is a major health problem in itself, there are now indications that elevated ozone levels also raise the allergen content of pollen. A team from the Medical University of Vienna and the Austrian Institute of Technology have investigated the reasons for this phenomenon. Ozone Stimulates Rye The team behind project leader Prof. Rudolf Valenta of the Centre for Pathophysiology, Infectiology and Immunology at the Medical University of Vienna cultivated two different rye cultivars under controlled environmental conditions. One group of plants was exposed to elevated ozone concentrations (79 parts per billion) for part of the time. This value is more than three times the normal ozone concentration at ground level, i.e. 22 ppb, and corresponds to the health-endangering peak ...
Long familiar in major urban areas, smog - what we experts call ground-level ozone pollution - is quickly becoming a serious problem in the rural mountain west, thanks to rapid expansion in oil and gas development. Smog can cause serious health impacts like aggravated asthma, chronic bronchitis, heart attacks, and even premature death. In areas like the Upper Green River Basin in Wyoming, smog levels have sometimes rivaled those in Los Angeles.. Now, the Environmental Protection Agency and several western states are putting the pieces in place to fix this problem: EPA through proposed revisions to the health-based ozone standard that will better protect people from pollution, and states like Wyoming and Colorado through strong policies that are helping to reduce the sources of ozone pollution in the oil and gas industry.. In official public comments filed this week with EPA, EDF and a broad coalition of western environmental and conservation groups supported a more protective ozone standard ...

Multivariate data analysis methods were applied to study the geographical and temporal distribution of tropospheric ozone in Catalonia (North-East Spain). Ozone data were collected during the period 2000-2004 in 41 sampling stations. Data analysis by multivariate curve resolution alternating least squares (MCR-ALS) allowed the recognition of three sub-regions within Catalonia according to their ozone variation patterns. Representation of loadings by means of geographical information systems (GIS) allowed a better visualisation of these areas. Daily, weekly and annual ozone profiles were determined for each sub-region. Principal component analysis (PCA) was applied within each sub-region to unravel the relationship between ozone variation and some other parameters, such as atmospheric pollutants (SO2, H2S, NO, NO2, CO and particulate matter), as well as meteorological variables (temperature, relative humidity, solar radiation, pressure, precipitation and wind speed ...
Abstract In this work, an in-situ ozone treatment is carried out to improve the interface thermal stability of HfO2/Al2O3 gate stack on germanium (Ge) substrate. The micrometer scale level of HfO2/Al2O3 gate stack on Ge is studied using conductive atomic force microscopy (AFM) with a conductive tip. The initial results indicate that comparing with a non in-situ ozone treated sample, the interface thermal stability of the sample with an in-situ ozone treatment can be substantially improved after annealing. As a result, void-free surface, low conductive spots, low leakage current density, and relative high breakdown voltage high-κ/Ge are obtained. A detailed analysis is performed to confirm the origins of the changes. All results indicate that in-situ ozone treatment is a promising method to improve the interface properties of Ge-based three-dimensional (3D) devices in future technology nodes.. ...
The potential mechanisms of action of ozone therapy are reviewed in this paper. The therapeutic efficacy of ozone therapy may be partly due the controlled and moderate oxidative stress produced by the reactions of ozone with several biological components. The line between effectiveness and toxicity of ozone may be dependent on the strength of the oxidative stress. As with exercise, it is well known that moderate exercise is good for health, whereas excessive exercise is not. Severe oxidative stress activates nuclear transcriptional factor kappa B (NFκB), resulting in an inflammatory response and tissue injury via the production of COX2, PGE2, and cytokines. However, moderate oxidative stress activates another nuclear transcriptional factor, nuclear factor-erythroid 2-related factor 2 (Nrf2). Nrf2 then induces the transcription of antioxidant response elements (ARE). Transcription of ARE results in the production of numerous antioxidant enzymes, such as SOD, GPx, glutathione-s-transferase(GSTr),

AMHERST, Mass. - A new study assessing the influence of species diversity of canopy trees on the amount of ozone precursors a forest emits suggests that atmospheric chemistry models in use now may underestimate the importance of tree species mix and size to ozone pollution, says lead author Alexander Bryan, a postdoctoral fellow in the Northeast Climate Science Center at the University of Massachusetts Amherst.. Details appear in an early online edition of the journal, Atmospheric Environment. As Bryan explains, Ozone pollution models do really well at predicting air quality in urban areas because thats where the problem started. Our atmospheric chemistry models have all been tested and optimized for urban air quality studies. But when we try to put those same models to the test in the forest regime without cars and factories, the models break down.. Current models usually represent the forest as a single dominant tree species or a blend of a few, so they may not capture the right mix of ...
Footnote: Ground-level ozone is formed from pollutants emitted from cars, power plants, and other sources. The national ambient air quality standard for ozone is 0.070 parts per million (ppm); concentrations above 0.070 ppm are considered unhealthy, especially for sensitive groups such as children, asthmatics, and the elderly. Ozone concentrations are measured and averaged over 8-hour testing periods; then, the number of days per year exceeding the standard is calculated. For counties with more than one monitoring site, data are reported for sites recording the most days above 0.070 ppm. Data are limited because (i) monitoring stations are usually in urban areas, and (ii) ozone samples are taken every three days or during times of the year when air pollution is very high. In addition, not all counties are monitored, and data are only provided for counties with monitors that meet completeness criteria. State-level data are averaged from county-level data and should be treated with caution. N/A ...
Wastewater ozone treatment is an advanced form of wastewater treatment. It uses the highly reactive properties of ozone, combined with biological and other impurities to render them harmless or converted into matter that can be easily removed and treated further. Questions have been raised about the high energy requirement needed to convert oxygen into ozone, but the advantages of no residue and odor have created an effective lobby for its continued use for wastewater treatment. What is ozone, primary treatment of wastewater and wastewater ozone treatment Is a form of advanced wastewater treatment are the topics dealt with here.

Ozone is probably one of the most miraculous healing therapies available on our planet at this time. Through its oxygenating power, it successfully treats and cures a wide range of serious degenerative conditions including cancer, cardiovascular disease, diabetes, liver, and kidney disease. More Than Hot Air Ozone is very potent electrified or energized oxygen (O3). Oxygen is more essential to life than food and water. Without it, we would die in minutes but in big cities the levels in the air are decreasing, causing widespread ill health. Oxygen is carried to every part of the body by the red blood cells and is essential for the functioning of every cell in the body, as well as stimulating a healthy immune system. Ozone also forms a protective layer around the earth; but some scientists point to the danger of high ozone readings as the cause of respiratory problems, so many are prejudiced, dismissive, and simply refuse to look into it. Yet ozone therapy has been in use since the 1800s; and in ...
Autohemotherapy - also known as Ozone IV Treatment or Ozone Therapy - is a procedure in which a pint to a quart of blood is drawn into a closed sterile glass device specifically made for this therapy.

Autohemotherapy or Ozone IV Treatment has proven safe and effective in more than a million treatments in Europe over the past several decades. A profoundly beneficial medical therapy, it is used by medical doctors in the treatment of almost all diseases and metabolic disorders.. ...
Surface ozone records from ten polar research stations were investigated for the dependencies of ozone on radiative processes, snow-photochemisty, and synoptic and stratospheric transport. A total of 146 annual data records for the Arctic sites Barrow, Alaska; Summit, Greenland; Alert, Canada; Zeppelinfjellet, Norway; and the Antarctic stations Halley, McMurdo, Neumayer, Sanae, Syowa, and South Pole were analyzed. Mean ozone at the Northern Hemisphere (NH) stations (excluding Summit) is 5 ppbv higher than in Antarctica. Statistical analysis yielded best estimates for the projected year 2005 median annual ozone mixing ratios, which for the Arctic stations were 33.5 ppbv at Alert, 28.6 ppbv at Barrow, 46.3 ppbv ppb at Summit and 33.7 ppbv at Zeppelinfjellet. For the Antarctic stations the corresponding ozone mixing ratios were 21.6 ppbv at Halley, 27.0 ppbv at McMurdo, 24.9 ppbv at Neumayer, 27.2 ppbv at Sanae, 29.4 ppbv at South Pole, and 25.8 ppbv at Syowa. At both Summit (3212 m asl) and South ...
Ozone strengthens your immune system - Ozone is a potent regulator of the immune system. When the immune system is overactive (as in auto-immune disease), ozone will calm it down. Conversely, when the immune system is under-active as in chronic infections, ozone will stimulate it. This unique ability of ozone stems from its activation of immune related messenger molecules, so called cytokines, like gamma interferon, interleukin-2, colony stimulating factor, and TNF-alpha, to name just a few.. Ozone kills bacteria and viruses on contact - Ozone interferes with the metabolism of bacterium-cells, most likely through inhibiting and blocking the operation of the enzymatic control system. A sufficient amount of ozone breaks through the cell membrane, and this leads to the destruction of the bacteria. Unlike bacteria, viruses multiply only within the host cell. They transform protein of the host cell into proteins of their own. Ozone destroys viruses by diffusing through the protein coat into the ...

Ozone is a gas that is present naturally in the atmosphere. Chemical formula of the ozone is O3 because three oxygen atoms are present in an ozone molecule .On the basis of presence of Ozone, the atmosphere is divided into two regions, troposphere and stratosphere. The troposphere is the closest region from the earth (10- 16 kilometers from the earth surface) and about 10% of the atmospheric ozone is present in this zone. Similarly the stratosphere is 50 kilometers altitude and about 90 % of the ozone is present in this region. Ozone was firstly produced in the laboratory by the European researcher C. F. Schonbein in 1839. Ozone was firstly used commercially in 1907 in municipal water supply treatment in Nice and in 1910 in St. Petersburg the general ozone generation. In order to produce ozone molecule, firstly we split the diatomic oxygen. The resulting free radical oxygen reacts with diatomic oxygen to form the tri-atomic ozone molecule. Nevertheless, in order to break the bond between two ...

Air pollution by ozone causes airway irritation and inflammation, representing a major health issue. Ozone is highly reactive-eliciting rapid and dose-dependent disruption of the respiratory barrier with acute desquamation and necrosis of epithelial cells, and inducing inflammation and airway hyperreactivity. Chronic ozone exposure leads to rarefication of alveolar septae with emphysema and fibrosis, and chronic lung inflammation mimicking changes associated with chronic obstructive pulmonary disease (COPD). Reactive oxygen species (ROS) is a critical effector in ozone-induced inflammation, systemic metabolic and neural hyperreactivity and cell death. In addition, it is now clearly recognized that a strong innate immune response to ozone may contribute to ozone-induced pathology and and alteration of the lungs response to infection.In this Research Topic, we aim to review ozone-induced respiratory pathology and disease based on (i) human exposure data and epidemiological evidence; (ii) on whole animal

Why should we worry about ozone?. Ozone is an extremely harmful gas -- particularly for those involved in outdoor activities. Just a few hours of exposure to it can trigger serious health problems, especially among those who are already suffering from respiratory and asthmatic problems. Ozone worsens symptoms of asthma, leads to lung function impairment and damages lung tissues. Chest pain, coughing, nausea, headaches and chest congestion are common symptoms. It can even worsen heart disease, bronchitis and emphysema. It increases emergency hospital visits and admissions related to respiratory diseases.. Scientists inform that ozone is a powerful oxidiser, which means it can damage cells in a process akin to rusting. Children and the elderly are at special risk. International studies have also found a strong association between ozone and daily premature death counts; deaths related to ozone exposure are more likely among people with pre-existing diseases. Ozone that gets created in the polluted ...

The answer to this is not known. Daily experimental ozone exposure does affect the post-natal development of the respiratory tract in nonhuman primates. Some epidemiological studies suggest that young adults raised in areas of higher air pollution have a greater degree of airway obstruction than similar adults raised in areas of lower air pollution. Also, there is some evidence that long-term ozone exposure may increase the risk of developing new asthma, particularly in males. On the other hand, because there are many factors (genetic and environmental) that may interact to cause asthma, long-term ozone exposure alone does not appear to account for a large part of the asthma or other respiratory disease in the population living in some cities of the United States with high ozone levels.. Top of Page. 6. Should I advise my healthy patients without asthma to reduce exposure when air quality is unhealthy even if they do not experience any acute symptoms? ...
Ozone therapy is a beneficial therapy that helps to restore and oxygenate the body. It can help to help purify the body and remove toxins while promoting health and healing.

Ozone, a common outdoor air pollutant is a highly reactive gas and a major component of smog. The U.S. Environmental Protection Agency (EPA) has set a National Ambient Air Quality Standard for ozone of 0.12 parts per million [ppm] that should not be exceeded for more than one hour, once per year. This standard is based largely on scientific data documenting the effects of short-term exposure on lung function in humans. The standard is currently being reevaluated by the EPA. Because ozone can damage cells, prolonged or repeated exposures may be a risk factor for lung cancer. To assess this issue, the National Toxicology Program (NTP) conducted an animal bioassay to evaluate ozones carcinogenicity in rodents. Another public health concern is that prolonged exposure to ozone may damage the cells that line the airways, leading to functional changes in the components of the respiratory tract.. The nose is the first line of defense against inhaled pathogens, dusts, and irritant gases; thus, changes ...
The terms chronic fatigue syndrome and myalgic encephalomyelitis describe a complex physical illness characterized by debilitating fatigue, post-exertional malaise, pain, cognitive problems, sleep dysfunction and an array of other immune, neurological and autonomic symptoms. At the MEDE Clinic of Sacile, Italy, from February 2016 to December 2017, we have treated 65 patients, with auto hemo transfusion, according to the Scientific Society of Oxygen Ozone Therapy (SIOOT) protocols, twice a week for one month and twice a month as maintenance therapy. In conclusion, at our knowledge this is the largest study of patients with chronic fatigue syndrome treated with ozone therapy. Oxygen ozone therapy is an effective therapy in the treatment of chronic fatigue syndrome. However, more patients are needed and in particular a longer follow up is a necessary. In the meantime, ozone therapy seems a treatment that, also because without any side effect, is possible to be proposed to patients with chronic ...
In a battle between Ozone and the Ebola Virus - who wins? Instant spoiler alert: We dont know.. [Update December 2015: In 2015 Dr. Rowen, Dr. Robins, Dr. Carew, Dr. Kamara and Mohamed Ibrahim Jalloh published a paper describing 5 cases of patients who had developed typical symptoms of Ebola virus infection after close contacts with other confirmed Ebola infected patients. All 5 patients regained health after just a few DIVs (direct ozone IV), rectal ozone insufflations and the ingestion of ozonated water. Here the full report.]. The best shot we had at finding out was when Dr. Robert Rowen and Dr. Howard Robins went to Sierra Leone in October 2014 to train doctors in using ozone therapy on Ebola patients. Unfortunately, the two doctors were prohibited from fulfilling their missions goal when staff who were scheduled to work with them was threatened by the office of the Minister of Health of Sierra Leone (Your job will be in jeopardy if you allow them to use ozone therapy on anyone., Dr. ...
Two species found in temperate calcareous and mesotrophic grasslands (Dactylis glomerata and Leontodon hispidus) were exposed to eight ozone treatments spanning preindustrial to post-2100 regimes, and late-season effects on stomatal functioning were investigated. The plants were grown as a mixed community in 14 L containers and were exposed to ozone in ventilated solardomes (dome-shaped greenhouses) for 20 weeks from early May to late September 2007. Ozone exposures were based on O-3 concentrations from a nearby upland area, and provided the following seasonal 24 h means: 21.4, 39.9 (simulated ambient), 50.2, 59.4, 74.9, 83.3, 101.3 and 102.5 ppb. In both species, stomatal conductance of undamaged inner canopy leaves developing since a midseason cutback increased linearly with increasing background ozone concentration. Imposition of severe water stress by leaf excision indicated that increasing background ozone concentration decreased the ability of leaves to limit water loss, implying impaired ...
The effects of ozone exposure on lettuce leaves were investigated by means of gas exchange, modulated chlorophyll a fluorescence and antioxidants systems. High ozone concentration decreased the rate of photosynthesis at light saturation level and changes in stomatal conductance and transpiration rate. However, an increase in intercellular CO2 concentration indicated a decrease in the carboxylation efficiency. These data agreed with a reduction of non-cyclic electron flow and lower capacity to reduce the quinone pool. Ozone affected the ascorbate pool and decreased ascorbate peroxidase activity, increased lipid peroxidation, altered membrane properties and reduced the development of non-photochemical quenching ...

Abstract: Tropospheric ozone, one of the most phytotoxic air pollutants, may specially impose in long-lived forest trees substantial reduction in productivity and biomass. European beech saplings grown in lysimeter around areas were used to monitor proteomic changes upon elevated ozone concentrations following four vegetation periods of exposure. A proteome study based on highly sensitive two-dimensional fluorescence difference gel electrophoresis (2-D DIGE) was performed to identify protein changes in European beech, the most important deciduous tree in Central Europe. Main emphasis was on identifying differentially expressed proteins after long-time period of ozone exposure under natural conditions rather than short-term responses or reactions under controlled conditions. Our results clearly demonstrate a response of European beech saplings to long-term ozone fumigation at the protein level. We indicate changes in the protein abundance of 142 protein spots; among them 59 were increased and 83

HAUPPAUGE, NY (04/28/2010)(readMedia)-- The American Lung Associations State of the Air 2010 report finds that Suffolk County is still the dirtiest county in New York for ozone pollution. According to the report, over 12 million New Yorkers - more than 62 percent of the states residents -- live in counties where unhealthy air threatens their lives and health. This year, 19 of the 33 counties in New York state with air quality monitors received failing grades. Nevertheless, the report also shows that efforts underway to clean up air pollution in the state are making a difference.. While many portions of this years report are encouraging, far too many Suffolk County residents are breathing air that puts their health at risk, said Scott T. Santarella, President and CEO of the American Lung Association in New York. While in many parts of the state we can see reduced emissions from sources including power plants and diesel engines, Long Island still has some significant air quality improvements ...
The U.S. Environmental Protection Agency (EPA) promulgates the National Ambient Air Quality Standards (NAAQS) on the basis of scientific information contained in air quality criteria issued under Section 108 of the Clean Air Act. The previous ozone (03) criteria document, Air Quality Criteria for Ozone and Other Photochemical Oxidants, was released in August 1986 and a supplement, Summary of Selected New Information on Effects of Ozone on Health and Vegetation, was released in January 1992. These documents were the basis for a March 1993 decision by EPA that revision of the existing l-h NAAQS for 03 was not appropriate at that time. That decision, however, did not take into account some of the newer scientific data that became available after completion of the 1986 criteria document. The purpose of this revised air quality criteria document for 03 and related photochemical oxidants is to critically evaluate and assess the latest scientific data associated with exposure to the concentrations of ...
The objective of this study was to compare the physico-chemical characteristics and antioxidant activity of ozone-treated papaya fruit and untreated fruit. Freshly harvested papaya fruit were exposed continuously to ozone fumigation (0, 1.5, 2.5, 3.5 and 5 ppm) for 96 h prior to ambient storage at 25 ± 3oC and 70 ± 5% relative humidity (RH) for up to 14 days. The fruit exposed to 2.5 ppm ozone had higher levels of total soluble solids (25.0%), ascorbic acid content (12.4%), β-carotene content (19.6%), lycopene content (52.1%), and antioxidant activity (30.9%), and also reduced weight loss (11.5%) at day 10 compared to the control. The sensory attributes of papaya treated with 2.5 ppm ozone was superior in sweetness and overall acceptability. These results support the application of ozone as a non-thermal and safe food preservation technique for papaya which can benefit both the producers and consumers.. ...
Boston, Mass. - May 30, 2013) - Unhealthy air quality, due to ground-level ozone, is expected for most of Conn., R.I., central and southern Mass. (including Springfield, Worcester, Cape Cod and the Islands), coastal N.H. and most of coastal Maine for Friday, May 31, 2013. Elevated smog levels are expected to continue through Saturday. We expect Friday to be another unhealthy air quality day in many parts of southern and coastal New England, said Curt Spalding, regional administrator of EPAs New England office. On these days, EPA and the medical community suggest that people limit their strenuous outdoor activity. Further, everybody can help reduce smog-forming emissions by driving less and by setting air conditioner thermostats a few degrees higher. The ozone standard is 0.075 parts per million (ppm) on an 8-hour average basis. Air quality alerts are issued when ozone concentrations exceed, or are predicted to exceed, this level. Exposure to elevated ozone levels can cause breathing ...
Four-week-old velvet beans (Mucuna pruriens L.) were fumigated with ozone, isoprene and propene both singly and in combination (hydrocarbon+oxidant) in controlled-environment chambers for a 4 week period. Measurements were made of total soluble protein, ascorbate, dehydroascorbate, lipid peroxidation, and glutathione reductase activity in mature and young velvet bean leaves.Significant increases in soluble protein concentrations with respect to the controls were found in plants fumigated with propene and isoprene+ozone for young leaves, and ozone only for mature leaves. The analysis of ascorbate concentrations in young leaves showed a significant increase in total ascorbate for propene-fumigated plants a significant decrease in the level of the oxidized form (dehydroascorbate) for ozone and isoprene+ozone-treated plants, and a significant increase in the reduced form for plants fumigated with propene, propene+ozone and isoprene+ozone. The analysis of ascorbate levels in mature leaves showed no ...
The details of polar ozone hole formation differ from that of mid-latitude thinning, but the most important process in both is catalytic destruction of ozone by atomic halogens.[1] The main source of these halogen atoms in the stratosphere is photodissociation of man-made halocarbon refrigerants (CFCs, freons, halons.) These compounds are transported into the stratosphere after being emitted at the surface.[2] Both types of ozone depletion were observed to increase as emissions of Halocarbons increased. CFCs and other substances contributing to this effect are referred to as ozone-depleting substances (ODS). Since the ozone layer prevents most harmful UVB wavelengths (280-315 nm) of ultraviolet light (UV light) from passing through the Earths atmosphere, observed and projected decreases in ozone have generated worldwide concern. As a result, the Montreal Protocol has been adopted. The treaty bans the production of CFCs, halons as and other ozone-depleting chemicals such as carbon tetrachloride ...
The latest Scientific Assessment of Ozone Depletion reveals a healing ozone layer, global warming reduction potential, and options for more ambitious climate action.. The quadrennial review from the Scientific Assessment Panel of the Montreal Protocol will be presented here at the 30th Meeting of the Parties to this historic accord. Its findings confirm first and foremost that actions taken under the Montreal Protocol have led to long-term decreases in the atmospheric abundance of controlled ozone-depleting substances (ODSs) and the ongoing recovery of stratospheric ozone.. Evidence presented by the authors shows that the ozone layer in parts of the stratosphere has recovered at a rate of 1-3% per decade since 2000. At projected rates, Northern Hemisphere and mid-latitude ozone is scheduled to heal completely by the 2030s followed by the Southern Hemisphere in the 2050s and polar regions by 2060. The ozone layer protects life on Earth from harmful levels of ultraviolet rays from the sun.. It is ...

Part of the reason the new calculations give a larger effect is that they include the effect methane has on air pollution. A major component of air pollution is near-surface-level or tropospheric ozone, which is not directly emitted, but is instead formed chemically from methane other hydrocarbons, carbon monoxide and nitrogen oxides. The IPCC report includes the effects of tropospheric ozone increases on climate, but it is not attributed to particular sources. By categorizing the climate effects according to emissions, Shindell and colleagues found the total effects of methane emissions are substantially larger. In other words, the true source of some of the warming that is normally attributed to smog is really due to methane that leads to increased smog ...
The sensitivity of Arctic ozone loss to polar stratospheric cloud volume (VPSC) and chlorine and bromine loading is explored using chemistry and transport models (CTMs). One simulation uses multi-decadal winds and temperatures from a general circulation model (GCM). Winter polar ozone loss depends on both equivalent effective stratospheric chlorine (EESC) and polar vortex characteristics (temperatures, descent, isolation, polar stratospheric cloud amount). The simulation reproduces a linear relationship between ozone loss and VPSC in agreement with that derived from observations for 1992-2003. The relationship holds for EESC within $85% of its maximum ($1990-2020). For lower EESC the ozone loss varies linearly with EESC unless VPSC $ 0. A second simulation recycles a single years winds and temperatures from the GCM so that polar ozone loss depends only on changes in EESC. This simulation shows that ozone loss varies linearly with EESC for the entire EESC range for constant, high VPSC.. ...
This video shows the status of the ozone hole between July 1, 2012 to October 19, 2012. The hole reached its maximum on September 22, 2012. Credit: NASA/Goddard Space Flight Center. Washington - The average area covered by the Antarctic ozone hole this year was the second smallest in the last 20 years, according to data from NASA and National Oceanic and Atmospheric Administration (NOAA) satellites. Scientists attribute the change to warmer temperatures in the Antarctic lower stratosphere.. The ozone hole reached its maximum size September 22, covering 8.2 million square miles (21.2 million square kilometers), or the area of the United States, Canada and Mexico combined. The average size of the 2012 ozone hole was 6.9 million square miles (17.9 million square kilometers). The September 6, 2000 ozone hole was the largest on record at 11.5 million square miles (29.9 million square kilometers).. The ozone hole mainly is caused by chlorine from human-produced chemicals, and these chlorine levels ...

Advantages of ozone generators. Ozone gas can successfully be used to remove impurities from water in case of some applications. The reason behind this is that very high amounts of ozone can be used in water and the chemical reactions take place underwater itself. Hence, they do not affect the human beings who arent in exposure to these reactions. Ozone at various concentrations can be used for water purification, bleaching, disinfection, to speed up the aging process of certain substances, removal of smoke and air purification by killing of germs like bacteria and viruses. Ozone generators in form of air purifiers eliminate tobacco smoke and other smells. They even reduce the smell of smoke in fire refurbishment jobs and also that of bacteria, mould or viruses from the garbage. These devices also help to reduce the levels of bacteria present in food plants. As a matter of fact, ozone gas has a short life cycle in the air and thus decomposes to oxygen on its own.. Disadvantages of ozone ...
The first Ozone Pipeline Disinfection System (PDS) has now been operating for two years and a further two units were delivered to Sydney Water in March 2014. The trailers to date have proven to be reliable with no failures in service and have achieved their intended purpose. For a customer of the utility, the use of the ozone process is cost effective and reliable in achieving disinfection. When using the superchlorination process there may be a potential risk of customers accidently receiving highly chlorinated water. The Ozone process eliminates this risk. If Ozonated water were to be accidently released to customers the risk would be negligible as ozone decays very quickly. Download to find out more ...
Arctic ozone hole research. NASA scientist examining laser ozone mapping experiment data gathered over the Arctic by a DC-8 flying laboratory in January & February 1989. Initial results from DC-8 and high-altitude ER-2 flights showed a marked increase in concentrations of chemicals known to destroy ozone. Ozone protects us from the Suns harmful ultraviolet rays. In Antarctica, satellite data has revealed an ozone hole that has been growing in size & severity since 1980. Antarctic research in 1987, including ER-2 flights, confirmed that the hole is probably caused by chlorofluorocarbons (CFCs), man-made chemicals used in aerosols & refrigerants. - Stock Image E180/0045

N2 - We examined ozone-induced airway inflammatory responses in inbred mice, and progeny of crosses between them, to investigate genetic susceptibility to ozone. Nine strains of male mice (18-23 g, 5-7 wk) were exposed for 3 h to 2 ppm ozone (O3) or filtered air (control) and pulmonary inflammation was assessed 2, 6, and 24 h after exposure by inflammatory cell counts and total protein content in bronchoalveolar lavage (BAL). The time course of the response to O3 was consistent between the strains. The maximum change in polymorphonuclear leukocytes (PMNs) was detected 6 h after O3, and the maximum increase in BAL protein occurred 24 h postexposure. Air controls exhibited no detectable changes in the parameters of inflammation at ...
Abstract of paper by S. Fred Singer). The Direct and Indirect Climate Effects of Stratospheric Ozone Changes. Changes in solar activity produce well-recognized changes in stratospheric ozone through changes in solar extreme UV (EUV) radiation. Observations show a 2 to 3 percent variation of total ozone during the solar cycle, outside of the tropical belt. (Angell) The maximum occurs near the peak of the sunspot cycle; amplitude increases with latitude, from near zero in the tropical zone. Stratospheric ozone produces a positive radiative forcing, which is a large fraction of the forcing from GH gases. (Tett et al 1996) Thus, the direct climate effects of the ozone solar-cycle variation should amplify the solar-cycle changes in solar irradiance.. We also discuss the indirect effects of ozone changes on the terrestrial climate: 1) Changes in ozone can affect tropospheric circulation (Haigh). We suggest that this may lead to changes in cloudiness and /or the vertical distribution of water vapor, ...
Perhaps the single most successful international environmental agreement to date has been the Montreal Protocol Kofi Annan. Using atmospheric observations, we have monitored international progress on phasing out ozone depleting substances such as CFCs for over 30 years.. The Medusa Gas Chromatography Mass Spectrometry instrument, co-developed by the ACRG, provides high-precision measurements of more than 40 ozone depleting substances and other related gases. Using models, we have used these data to track how emissions of these substances continue to change in response to the Montreal Protocol..

Abstract. Over the past few decades, the geographical distribution of emissions of substances that alter the atmospheric energy balance has changed due to economic growth and air pollution regulations. Here, we show the resulting changes to aerosol and ozone abundances and their radiative forcing using recently updated emission data for the period 1990-2015, as simulated by seven global atmospheric composition models. The models broadly reproduce large-scale changes in surface aerosol and ozone based on observations (e.g. −1 to −3 % yr−1 in aerosols over the USA and Europe). The global mean radiative forcing due to ozone and aerosol changes over the 1990-2015 period increased by +0.17 ± 0.08 W m−2, with approximately one-third due to ozone. This increase is more strongly positive than that reported in IPCC AR5. The main reasons for the increased positive radiative forcing of aerosols over this period are the substantial reduction of global mean SO2 emissions, which is stronger in the ...
Field-grown yellow-poplar (Liriodendron tulipifera L.) werefumigated from May to October in 1992-96 within open-topchambers to determine the impact of ozone (O3) aloneor combined with elevated carbon dioxide (CO2) on saplinggrowth. Treatments were replicated three times and included: charcoal-filteredair (CF); 1 × ambient ozone (1 × O3);1·5 × ambient ozone (1·5 × O3);1·5 × ambient ozone plus 350 p.p.m.carbon dioxide (1·5 × O3 + CO2)(target of 700 p.p.m. CO2); and open-air chamberlessplot (OA). After five seasons, the total cumulative O3 exposure (SUM00 = sumof hourly O3 concentrations during the study) rangedfrom 145 (CF) to 861 (1·5 × O3) p.p.m. × h (partsper million hour). Ozone had no statistically significant effecton yellow-poplar growth or biomass, even though total root biomasswas reduced by 13% in the 1·5 × O3-exposedsaplings relative to CF controls. Although exposure to 1·5 × O3 + CO2 hada stimulatory effect on yearly basal area growth increment aftertwo seasons, ...

People most affected by air pollution include children, senior citizens, people who work or exercise outdoors and people with pre-existing respiratory disease.. Children make up about 25 percent of the population but account for approximately 40 percent of all asthma cases. Their lungs breathe faster and inhale more air and air pollution per pound of body weight than adults. Recent studies indicate that children active in high ozone environments have diminished lung capacity and more easily develop or exacerbate asthma and other respiratory illnesses.. In this article we will discuss the three most prevalent types of pollution in Maricopa County and the greatest health risk.. Ground-level ozone is the most widespread air quality problem not only in Maricopa County but in the United States. Approximately one out of every three people is susceptible to ozone-related health problems, including shortness of breath, coughing, wheezing, headaches, nausea, and throat and lung irritation.

Credit: NOAA GFDL]. Climate models such as those developed at GFDL can help researchers predict future levels of smog, enabling cost-benefit analyses for costly pollution control measures. The researchers compared results from a model called GFDL-AM3 to ozone measurements from monitoring stations over the course of the last 35 years, from 1980 to 2014.. Prior studies using global models poorly matched the ozone increases measured in western national parks. Lin and co-authors were able to match the measurements by narrowing their analysis to days when the airflow is predominantly from the Pacific Ocean.. Modeling the sources of air pollution can help explain where the ozone measured in the national parks is coming from, explained Lin. The model allows us to divide the observed air pollution into components driven by different sources, she said.. The team also looked at other contributors to ground-level ozone, such as global methane from livestock and wildfires. Wildfire emissions contributed ...

Objective(s):Cutaneous Leishmaniasis is a common and endemic disease in Khorasan province in North-East of Iran. The pentavalant antimony (Sb V) is the mainstay of treatment that has many side effects and resistance to the drug has been reported. The microbicidal effect of ozone was proven in different microorganisms. Since there is no study in this respect and to achieve a low cost and effective treatment, we decided to evaluate the efficacy of ozone against promastigotes of Leishmania major,in vitro. Materials and Methods: Ozonated olive oil was prepared after production of ozone by bubbling ozone-oxygen gas produced by ozone generator through olive oil until it solidified. Promastigotes of L. major were cultivated in two phasic media. After calculation of the number of promastigotes, they were incubated with ozonated olive oil (0, 0.626, 0.938, 1.25, 2.5, 5, 10 mcg/ml) at 28 °c for 24 hr. Parasites survival percentage was evaluated using MTS and microscopic assay, and then compared with Glucantime

  • Good" ozone occurs naturally about 10 to 30 miles above the Earth's surface. (
  • CFCs and halons deplete the Earth's ozone layer because they break up in the stratosphere, releasing chlorine or bromine atoms - powerful catalysts which convert ozone into oxygen. (
  • Earth's protective ozone layer is on track for recovery within the next few decades according to a new assessment by 282 scientists from 36 countries. (
  • The average amount of ozone in Earth's atmosphere is 300 Dobson Units, equivalent to a layer 3 millimeters (0.12 inches) thick, about the height of 2 pennies stacked together. (
  • WASHINGTON D.C. -- The Montreal Protocol, the international treaty adopted to restore Earth's protective ozone layer in 1989, has significantly reduced emissions of ozone-depleting chemicals from the United States. (
  • The new analysis, based on data collected by NOAA's atmospheric monitoring network, confirms that the Montreal Protocol has been highly successful in the U.S. in its primary goal - reducing emissions of manufactured chlorine-based chemicals that, in addition to depleting ozone world-wide, create a hole the size of the continental U.S. in the Earth's protective ozone layer over the Antarctic each September and October. (
  • This means that 300 total shuttle flights will completely destroy the Earth's protective ozone shield. (
  • Ozone is Earth's natural sunscreen, shielding life from dangerous solar ultraviolet radiation. (
  • Human-produced chemicals in our atmosphere-such as chlorofluorocarbons (CFCs), used for many years as refrigerants and in aerosol spray cans-have depleted the Earth's ozone layer. (
  • By late 2019, levels were falling by about 1% a year - the fastest on record, according to the report - showing that the world was back on track to repairing the damage to the Earth's ozone layer by mid-century. (
  • FILE - In this NASA false-color image, the blue and purple shows the hole in Earth's protective ozone layer over Antarctica on Oct. 5, 2022. (
  • Earth's protective ozone layer is slowly but noticeably healing at a pace that would fully mend the hole over Antarctica in about 43 years, a new United Nations report says. (
  • A once-every-four-years scientific assessment found recovery in progress, more than 35 years after every nation in the world agreed to stop producing chemicals that chomp on the layer of ozone in Earth's atmosphere that shields the planet from harmful radiation linked to skin cancer, cataracts and crop damage. (
  • High in Earth's atmosphere (miles above the surface), ozone forms from natural processes. (
  • When asked for his opinion on the research, Bert Brunekreef, PhD, professor of environmental epidemiology and director of the Institute for Risk Assessment Sciences, University of Utrecht, the Netherlands, told Medscape Medical News that we might need to worry more about climate-change-induced changes in particulate matter concentrations than ozone concentrations. (
  • Weekly activity of influenza (influenza-like illness (ILI) + proxy) of a) influenza A(H3N2), b) influenza A(H1N1), c) influenza A(H1N1)pdm09 and d) influenza B (black lines) along with the 44 predefined epidemics (grey bars) of these virus type and subtypes, and e) the weekly smoothed average of ozone (O 3 ) concentrations in Hong Kong from 1998 to 2013. (
  • Low ozone concentrations stimulate cytoskeletal organization, mitochondrial activity and nuclear transcription. (
  • Ozone therapy is a modestly invasive procedure based on the regeneration capabilities of low ozone concentrations and used in medicine as an alternative/adjuvant treatment for different diseases. (
  • Ozone formation and destruction is dependent on emissions, concentrations and ratios of precursors (mainly VOC, CO and NO X ), and on the amount and intensity of sunlight. (
  • In urban areas, the ozone concentrations may be lower than the rural ('background') concentrations due to chemical scavenging by local nitrogen oxide emissions (see for example Figure 3, which shows that the occurrences of exceedances are in general highest at rural stations). (
  • Today kicks off the official ozone season, when higher ozone concentrations can make air unhealthy to breathe. (
  • Mixed with hot summer days, this may mean higher ozone concentrations, which can translate to more asthma, more bronchitis, more emphysema and more complications from cardiovascular disease. (
  • Strong sunlight and hot weather cause ground - level ozone to form in harmful concentrations in the air. (
  • This means that during several days each year, these counties experience high concentrations of ground - level ozone in the air. (
  • However, small effect of ground-level ozone on mortality was due to low concentrations of ground-level ozone. (
  • Additional studies will be needed to confirm short-term effects of ground-level ozone on mortality with varying concentrations. (
  • Within the context of the yearly improvement of particulate matter (PM) pollution in Chinese cities, Surface ozone (O3) concentrations are increasing instead of decreasing and are becoming the second most important air pollutant after PM. Long-term exposure to high concentrations of O3 can have adverse effects on human health . (
  • Air samples contained concentrations of hydrogen-chloride (7647010) below the limit of detection and ozone (10028156) concentrations to 60 micrograms per cubic meter, below the OSHA standard of 200 micrograms per cubic meter. (
  • Breathing in ground-level ozone can be harmful to your health. (
  • The good news is there's a lot you can do to protect yourself and your family from the health effects caused by ground-level ozone. (
  • When ground-level ozone levels are high, take steps to limit the amount of air you breathe in while you're outside. (
  • Unlike ozone in the stratosphere, which benefits life on Earth by blocking ultraviolet radiation from the sun, ground-level ozone can trigger a number of health problems. (

  • Ground-level ozone is a colorless and highly irritating gas that forms just above the earth\’s surface. (
  • During the warm, sunny days, NOx and VOC are more likely to combine with oxygen and form ground-level ozone. (
  • The ground-level ozone is a major contributory effect to global warming as less airborne carbon dioxide (CO₂) is now being captured by plants and trees. (
  • High levels of ground-level ozone cause stomata of plants to be closed. (
  • Exposure to ground-level ozone has been linked to pre-mature mortality and a range of morbidity health end-points such as hospital admissions and asthma symptom days. (
  • The purpose of this study was to investigate the short term effects of ground-level ozone exposure on health outcomes among residents of Bangkok, Thailand. (
  • Ground-level ozone was marginally associated with death from unclassified causes (RR=1.234, 95% CI=0.998, 1.525). (
  • All of the relative risks are for 10 part per billions (ppb) increase in ground-level ozone concentration. (
  • Recommendations: There was some evidence that ground-level ozone produced substantial adverse health effects among Bangkok\’s residents. (
  • The association between ground-level ozone and mortality was largest for unclassified deaths. (
  • But ground-level ozone can be bad for your health and the environment. (
  • Ground-level ozone is one of the biggest parts of smog. (
  • Besides meteorological factors, it is also uncertain how common air pollutants such as ozone (O 3 ), sulfur dioxides (SO 2 ), nitrogen dioxide (NO 2 ), nitric oxide (NO) and particulate matter may affect influenza transmission [ 2 ]. (
  • Unless emissions of specific pollutants associated with the formation of ozone are sharply cut, most of the continental United States will experience more summer days with unhealthy air by 2050, the research shows. (
  • However, the research also showed that a sharp reduction in the emissions of certain pollutants would lead to dramatically decreased levels of ozone even as temperatures warm. (
  • The 6 pollutants that account for the large majority of air pollution worldwide and for which standards are usually specified include carbon monoxide (CO), ozone (O3), oxides of nitrogen (NOx), sulfur dioxide (SO2), lead (Pb) and suspended particulate matter (SPM). (
  • The AQI tells you about five major air pollutants in the U.S. that are regulated by the US Environmental Protection Agency, including ozone and particle pollution . (
  • Pollutants of major public health concern include particulate matter, carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide. (
  • They concluded that CF 3 O is much less efficient than chlorine at destroying ozone and that ozone loss caused by HFCs is likely to be greatest in the lower part of the stratosphere, but is still negligible overall. (
  • How do scientists really know what's going on between heights around 15 and 50 kilometers (10 and 30 miles) in the stratosphere, where ozone forms with the help of sunlight? (
  • In the stratosphere, it absorbs harmful solar ultraviolet ``light,'' which is why the strength of the ozone layer is important. (
  • This and other distinctive physical and chemical characteristics help ozone trackers keep tabs on the chemical's distribution throughout the stratosphere. (
  • And by some accounts, ozone levels in the upper stratosphere may now be increasing slightly. (
  • The only part of the atmosphere showing strong ozone recovery post-Montreal Protocol is the upper stratosphere, and that is exactly where the impact of rocket emissions will hit hardest," Robert Ryan, study co-author, said, as per the news release. (
  • The ozone holes high in the stratosphere over each of the polar regions have stopped growing due to the phase out of nearly 100 ozone-depleting substances once used in products like refrigerators and spray cans, United Nations scientists said today in a new report. (
  • The ozone layer is part of the stratosphere and is very important because it blocks 99% of the ultraviolet radiation from the sun. (
  • In the upper stratosphere and in the ozone hole we see things getting better," said Paul Newman, co-chair of the scientific assessment. (
  • WE'VE heard of the Antarctic ozone hole and about possible global changes in the ozone layer. (
  • The image above shows the Antarctic ozone hole on September 13, 2014, as observed by the Ozone Monitoring Instrument (OMI) on the Aura satellite. (
  • The Antarctic ozone hole reached its annual peak size on Sept. 11, according to scientists from NASA and the National Oceanic and Atmospheric Administration (NOAA). (
  • The Antarctic ozone hole in 1979, left, grew to encompass nearly all of the continent in 2008. (
  • Over the past decade, global ozone and ozone in the Arctic and Antarctic regions is no longer decreasing but is not yet increasing," the study finds. (
  • The ozone layer outside the polar regions will recover to pre-1980 levels before the middle of this century, but the annual springtime ozone hole over the Antarctic is expected to take much longer, the study projects. (
  • Natural weather patterns in the Antarctic also affect ozone hole levels, which peak in the fall. (
  • After a decade of cracking down on power plants in an effort to clean up ozone air pollution, environmental regulators in Ohio this year zeroed in on another culprit - deodorant. (
  • It's unclear whether Front Range residents might someday be asked to use retooled deodorant - but the region must come up with a new plan to reduce rising levels of ozone pollution. (
  • States already struggling with ozone violations - such as Missouri and Ohio - have come up with an array of inventive ways to curb pollution. (
  • In Dallas, cars, trucks and buses contribute about 70 percent of the ozone- forming air pollution. (
  • The city's plan to combat ozone targets those sources and places less emphasis on pollution that comes from smokestack industries. (
  • St. Louis' plan for combatting ozone has called for targeting major industrial sources of pollution that prior to 1990 had gone largely uncontrolled. (
  • Ozone pollution across the continental United States will become far more difficult to keep in check as temperatures rise, according to new research results. (
  • Ozone pollution also damages crops and other plants. (
  • Ozone pollution is not emitted directly. (
  • To examine the effects of climate change on ozone pollution, Pfister and colleagues looked at two scenarios. (
  • Click on the link below to see ozone pollution concentration maps. (
  • Ozone and particle pollution may harm the health of hundreds of thousands of Americans each year. (
  • Surface ozone pollution in China: Trends, exposure risks, and drivers. (
  • People are concerned about the impact on their health of the climate warming and stratospheric ozone depletion that Europe has been experiencing for the last century. (
  • The scientists measured how fast CF 3 O reacted with ozone, as well as the speeds of other reactions which determine the ozone depletion potentials of HFCs. (
  • Ravishankara and Howard estimated that the 'ozone depletion potential' of HFCs is a thousandth that of CFC-11, the compound whose ozone depletion potential is defined as 1.0. (
  • The abundance of most ozone-depleting substances in the atmosphere has dropped since the last assessment in 2010, and stratospheric ozone depletion has leveled off and is showing some signs of recovery. (
  • Burdakov also notes that the history of ozone depletion correlates closely with the increase of chlorine discharged by solid fuel rockets since 1981. (
  • Useful search terms for ozone include " triatomic oxygen. (
  • These in-line analyzers provide continuous monitoring of dissolved oxygen, dissolved CO2 and ozone in pure water treatment, bioreactors or other industrial processes. (
  • These transmitters are designed to integrate with dissolved oxygen, CO2 and/or ozone sensors for better process control. (
  • Ozone (O(3)) is a natural, highly unstable atmospheric gas that rapidly decomposes to oxygen. (
  • Ozone is a form of oxygen with three atoms per molecule. (
  • The NWK portable cordless ozone generator works by breaking apart oxygen molecules into single atoms, after which they then attach to other molecules in the air to form ozone. (
  • Ozone is an allotropic form of molecular oxygen consisting of three atoms of oxygen instead of the more common two. (
  • Ozone is three parts Oxygen, or O3. (
  • Ozone will only last a short period of time before it turns back into standard Oxygen. (
  • In fact, Ozone is roughly 20 times more soluble than Oxygen alone. (
  • How does an Ozone Sauna compare to a Hyperbaric Oxygen Chamber? (
  • Because Oxygen is not as soluble as Ozone, Hyperbaric Oxygen Chambers have to put the Oxygen under pressure. (
  • 1- the sauna itself, 2- an Ozone generator, 3- and a high purity Oxygen source that feeds the Ozone generator. (
  • For medical grade Ozone, a pure Oxygen source is required. (
  • To use an Ozone Sauna, simply connect your Oxygen source to the Ozone generator and feed the Ozone into the sauna. (
  • Ozone is a gas made out of oxygen. (
  • Ozone is three oxygen atoms joined together. (
  • Ozone is a highly reactive form of oxygen that can cause deterioration and damage to a variety of materials, including rubber, plastics, and fabrics. (
  • Ozone is an oxidizing agent that activates oxygen, which can effectively kill bacteria, viruses and fungi. (
  • Elsewhere in the broadcast, Maduro applauded two new alleged treatments as "out of sight": "rectal ozone therapy and intravenous ozone therapy. (
  • America's Food and Drug Administration (FDA) and Federal Trade Commission have banned the use of ozone therapy for coronavirus patients and warned consumers to avoid any marketing suggesting it is safe. (
  • According to the FDA , ozone is "a toxic gas with no known useful medical application in specific, adjunctive, or preventive therapy. (
  • Ozone Saunas are known as a form of transdermal Ozone therapy. (
  • Regarding the main therapeutic modalities used, new less invasive therapies have acquired space, such as ozone therapy, laser therapy associated with photodynamic therapy and drugs, such as vitamin, antifibrotic and anti-resorptive. (
  • This evidence map presents a graphical summary of clinical studies on the application of Ozone Therapy in cases of COVID-19. (
  • The video below shows the South Pole on the day of minimum ozone concentration between 1979 and 2013. (
  • Here, the globes show ozone data on the day that the minimum ozone concentration was reached over Antarctica, each year from 1979 and 2016. (
  • In 1987, international leaders crafted a treaty to phase out the production and consumption of these ozone-depleting chemicals. (
  • Ozone-depleting chemicals-which were once used for refrigerants, aerosol spray cans, insulation foam, and fire suppression-persist for decades in the atmosphere. (
  • Beyond the positive impact on the ozone layer, the banning of CFCs and similar compounds has had a positive effect on climate because such chemicals are also greenhouse gases. (
  • The growth of the ozone hole appears to have stopped thanks to the banning of most ozone-depleting chemicals. (
  • Another indication of the treaty's impact is increasing U.S. emissions of ozone-friendly chemicals, such as hydrofluorocarbons or HFCs. (
  • In the 1980s, governments around the world woke up to the destruction of the ozone layer and in 1987 negotiated the Montreal Protocol-an international treaty designed to protect the ozone layer by banning CFCs and similar ozone-depleting chemicals. (
  • It's the "landmark" agreement that regulates the production of ozone-depleting man-made chemicals. (
  • New analyses have shown that China has successfully cut the illegal production of ozone-destroying chemicals. (
  • In recent years, scientists had been alarmed by a sudden unexplained rise in ozone-attacking chemicals in the atmosphere . (
  • The international treaty, agreed in 1987 to ban the production of ozone-depleting chemicals, has been signed by almost every country in the world. (
  • The phase out of ozone-destroying chemicals is required under the Montreal Protocol on Substances That Deplete the Ozone Layer, an international agreement written to protect the stratospheric ozone layer, which last year achieved universal ratification. (
  • For most residential applications where you are injecting chlorine, air, ozone or other chemicals before your filtration system, the 15 or 30 Gallon Contact Tanks work good. (
  • Scientists and environmental advocates across the world have long hailed the efforts to heal the ozone hole - springing out of a 1987 agreement called the Montreal Protocol that banned a class of chemicals often used in refrigerants and aerosols - as one of the biggest ecological victories for humanity. (
  • Our success in phasing out ozone-eating chemicals shows us what can and must be done - as a matter of urgency - to transition away from fossil fuels, reduce greenhouse gases and so limit temperature increase," World Meteorological Organization Secretary-General Prof. Petteri Taalas said in a statement. (
  • The two chief chemicals that munch away at ozone are in lower levels in the atmosphere, said Newman, chief Earth scientist at NASA's Goddard Space Flight Center. (
  • A third generation of those chemicals, called HFC, was banned a few years ago not because it would eat at the ozone layer but because it is a heat-trapping greenhouse gas. (
  • The stratospheric ozone layer shields us from most of the damaging ultraviolet rays from the Sun. In 1974, scientists discovered that chlorine- and bromine-containing compounds such as chlorofluorocarbons (CFCs) and halons could deplete the ozone layer, and by the mid-1980s, they had observational evidence that it was happening. (
  • Meg Seki, acting executive secretary of Ozone Secretariat at the UN Environment Program (UNEP), credited the reversal to international cooperation and action in line with the Montreal Protocol on Substances that Deplete the Ozone Layer. (
  • The Montreal Protocol has "provided substantial co-benefits by reducing climate change," because many substances that deplete the ozone layer are also potent greenhouse gases, according to the report. (
  • The UNEP/WMO team cautioned that one of the key replacements for CFCs-hydrofluorocarbons (HFCs)-do not harm the ozone layer but they are potent greenhouse gases that could contribute substantially to climate change in the coming decades. (
  • Chlorine from CFCs was first identified as capable of destroying stratospheric ozone in 1974. (
  • Scientists first recognized the potential for harmful effects of CFCs on ozone in the early 1970s. (
  • Holes caused by chlorofluorocarbons (CFCs) have formed in ozone layer. (
