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
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 ...

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 ...
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 ...

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.. ...

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 ...
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 ...

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 ...

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 Environmental Protection Agency (EPA) implemented the 1-hour National Ambient Air Quality Standards (NAAQS) for ozone in 1990. Under this standard, the ozone threshold value was 125 parts per billion (ppb), measured as one-hour average concentration. An area met this ozone NAAQS if there were no more than three exceedances at any one monitor in the region in a three-year period.. Four counties in the North Central Texas (NCT) region were designated as nonattainment for the 1-hour ozone NAAQS in 1991. Those counties were Collin, Dallas, Denton, and Tarrant. On June 15, 2005, the 1-hour ozone NAAQS was revoked and replaced by the 8-hour ozone NAAQS. (see 1997 Ozone NAAQS).. On October 31, 2006, the region demonstrated attainment of the 1-hour ozone NAAQS , although it continues to be monitored due to EPAs anti-backsliding requirements. On October 16, 2008, the EPA issued a determination of attainment for the four one-hour nonattainment counties in NCT. ...
The phytotoxicity of ozone to plants is conditioned by a number of environmental factors, including the availability of soil water. These experiments were conducted to determine the interactive effects of plant water stress and ozone on the productivity(biomass) and physiology (photosynthesis, stomatal conductance) of soybean (Glycine max[L.] merr. cv "Davis") plants under controlled laboratory conditions. Two similar experiments were designed to examine plant response to two possible ozone - water stress interactions. The first experiment examined the influence of water stress in preconditioning plants to ozone exposure. Plants were maintained in a greenhouse under water-stressed (via soil drying) or non-stressed conditions for two weeks, followed by 8 hour daily exposures to 0, 0.2, 0.3, and 0.5 ppm ozone in controlled gas exchange chambers. Results indicated no consistent patterns in plant physiological response to ozone over two weeks of ozone exposures. In terms of foliar injury, ...
The photochemical mechanisms that give rise to the ozone layer were discovered by the British physicist Sidney Chapman in 1930. Ozone in the Earths stratosphere is created by ultraviolet light striking oxygen molecules containing two oxygen atoms (O2), splitting them into individual oxygen atoms (atomic oxygen); the atomic oxygen then combines with unbroken O2 to create ozone, O3. The ozone molecule is also unstable (although, in the stratosphere, long-lived) and when ultraviolet light hits ozone it splits into a molecule of O2 and an atom of atomic oxygen, a continuing process called the ozone-oxygen cycle, thus creating an ozone layer in the stratosphere, the region from about 10 to 50 kilometres (33,000 to 160,000 ft) above Earths surface. About 90% of the ozone in our atmosphere is contained in the stratosphere. Ozone concentrations are greatest between about 20 and 40 kilometres (12 and 25 mi), where they range from about 2 to 8 parts per million. If all of the ozone were compressed to ...

The Antarctic ozone hole was discovered in 1985 by Joe Farman, a scientist working with the British Antarctic Survey.. The stratosphere is the upper layer of the atmosphere, between approximately 15-50 kilometres above the earths surface. It is underlain by the troposphere. The tropopause is the zone of transition.. Ozone is a gas with molecules composed of three oxygen atom, consequently its chemical designation is O3. Ozone is removed from the atmosphere naturally. Microorganisms in the soil produce a gas called nitrous oxide (N2O). In the stratosphere, N2O is broken down into the nitrogen oxides NO and NO2. These react with ozone but are not themselves consumed. Human enhanced production of nitrogen oxides has resulted in an accelerated reduction of ozone content. In addition synthetic chemicals, such as chlorofluorocarbons (CFCs), also cause depletion of the sensitive ozone layer.. Current and future changes in the atmospheric ozone profile will have significant effects on the vertical ...

The actual concentration of ozone produced by an ozone generator depends on many factors. Concentrations will be higher if a more powerful device or more than one device is used, if a device is placed in a small space rather than a large space, if interior doors are closed rather than open and, if the room has fewer rather than more materials and furnishings that adsorb or react with ozone and, provided that outdoor concentrations of ozone are low, if there is less rather than more outdoor air ventilation.. The proximity of a person to the ozone generating device can also affect ones exposure. The concentration is highest at the point where the ozone exits from the device, and generally decreases as one moves further away.. Manufacturers and vendors advise users to size the device properly to the space or spaces in which it is used. Unfortunately, some manufacturers recommendations about appropriate sizes for particular spaces have not been sufficiently precise to guarantee that ozone ...

In many people, exposure to ozone, an irritant gas and ubiquitous air pollutant, causes reversible decreases in some measures of lung function, increases in airway reactivity, and the appearance of indicators of airway inflammation in lung fluids. Individuals having the greatest risk of developing such effects appear to be those who exercise or engage in moderate-to-strenuous physical activity. To estimate the health risk that ozone exposure may pose to humans, regulators need to know how much ozone reaches the target tissues in the respiratory tract. Measuring respiratory dose requires an instrument that (1) can monitor ozone concentrations at the airway opening (mouth or nose) rather than in the ambient air; (2) responds dynamically at a rapid rate relative to an individuals breathing rate; and (3) is sensitive enough to measure ozone levels at or below ambient levels (0.07 to 0.20 ppm in urban areas) for both resting and exercising subjects.

The effects of chronic exposure to ozone on leaf anatomy, cell ultrastructure and crop yield were studied. Severe cell damage was found, even at ambient ozone levels, mainly affecting the spongy parenchyma and areas near the stomata. Damage to the cell wall caused loss of cell contact, and loss of turgor pressure due to tonoplast disintegration, contributed to cell collapse. Phloem sieve plates were obstructed by callose accumulation, and damaged mesophyll cells increased their starch stores. Tuber yield fell sharply (24-44%), due to the biggest tubers becoming smaller, which affected commercial yield. These anatomical findings show the mechanisms of ozone effect on assimilate partitioning, and thus crop yield decrease, in potato. Further implications of ozone causing reductions in belowground biomass are also discussed ...
This was the first Arctic winter monitored by Aura, which was launched in July 2004. Auras Microwave Limb Sounder is contributing to our understanding of the processes that cause Arctic wind patterns to push ozone-rich air to the Arctic lower stratosphere from higher altitudes and lower latitudes. Through Auras findings, scientists can differentiate chemical ozone destruction from ozone level changes caused by air motions, which vary dramatically from year to year. "Understanding Arctic ozone loss is critical to diagnosing the health of Earths ozone layer," said Dr. Phil DeCola, Aura program scientist at NASA Headquarters, Washington. "Previous attempts to quantify Arctic ozone loss have suffered from a lack of data. With Aura, we now have the most comprehensive, simultaneous, global daily measurements of many of the key atmospheric gases needed to understand and quantify chemical ozone destruction." Ozone loss in Earths stratosphere is caused primarily by chemical reactions with chlorine ...
