Exhaled nitric oxide among pulpmill workers reporting gassing incidents involving ozone and chlorine dioxide. (1/131)

The aim of the study was to investigate whether measurement of nitric oxide in exhaled air could be used for assessing the effects of irritants on the respiratory system, in this case recurrent ozone gassing in an occupational setting. The study population comprised bleachery workers (n=56) from a Swedish pulpmill carrying out ozone-based pulp bleaching since 1992 and controls (n=39). Both groups were investigated by measuring NO in exhaled air, methacholine challenge test and answers to a questionnaire concerning history of respiratory symptoms and accidental exposure to ozone peaks. There was no significant difference in NO output between exposed subjects and controls (median 67.2 versus 55.0 nL x min(-1), p=0.64). However, among bleachery workers reporting ozone gassings, the median NO output was 90.0 nL x min(-1) compared to 58.8 nL x min(-1) among those not reporting such incidents (p=0.019). There was no relation between exhaled NO and the prevalence of respiratory symptoms or bronchial hyperresponsiveness. In a multiple regression model, only reported ozone gassings were associated (p=0.016) with NO output. The results indicate an association between previous response to ozone gassing and nitric oxide output. The increased nitric oxide output among the bleachery workers reporting peak ozone exposure may indicate that chronic airway inflammation is present. Further studies are needed to evaluate the extent to which nitric oxide can be used for biological monitoring of respiratory health effects, and to relate it to other markers of airway inflammation.  (+info)

Chlorine, chloramine, chlorine dioxide, and ozone susceptibility of Mycobacterium avium. (2/131)

Environmental and patient isolates of Mycobacterium avium were resistant to chlorine, monochloramine, chlorine dioxide, and ozone. For chlorine, the product of the disinfectant concentration (in parts per million) and the time (in minutes) to 99.9% inactivation for five M. avium strains ranged from 51 to 204. Chlorine susceptibility of cells was the same in washed cultures containing aggregates and in reduced aggregate fractions lacking aggregates. Cells of the more slowly growing strains were more resistant to chlorine than were cells of the more rapidly growing strains. Water-grown cells were 10-fold more resistant than medium-grown cells. Disinfectant resistance may be one factor promoting the persistence of M. avium in drinking water.  (+info)

Identification of a serine hydrolase as a key determinant in the microbial degradation of polychlorinated biphenyls. (3/131)

The ability of 2-hydroxy-6-oxo-6-phenylhexa-2,4-dienoate (HOPDA) hydrolase (BphD) of Burkholderia cepacia LB400 to hydrolyze polychlorinated biphenyl (PCB) metabolites was assessed by determining its specificity for monochlorinated HOPDAs. The relative specificities of BphD for HOPDAs bearing chlorine substituents on the phenyl moiety were 0.28, 0.38, and 1.1 for 8-Cl, 9-Cl, and 10-Cl HOPDA, respectively, versus HOPDA (100 mm phosphate, pH 7.5, 25 degrees C). In contrast, HOPDAs bearing chlorine substituents on the dienoate moiety were poor substrates for BphD, which hydrolyzed 3-Cl, 4-Cl, and 5-Cl HOPDA at relative maximal rates of 2.1 x 10(-3), 1.4 x 10(-4), and 0.36, respectively, versus HOPDA. The enzymatic transformation of 3-, 5-, 8-, 9-, and 10-Cl HOPDAs yielded stoichiometric quantities of the corresponding benzoate, indicating that BphD catalyzes the hydrolysis of these HOPDAs in the same manner as unchlorinated HOPDA. HOPDAs also underwent a nonenzymatic transformation to products that included acetophenone. In the case of 4-Cl HOPDA, this transformation proceeded via the formation of 4-OH HOPDA (t(12) = 2.8 h; 100 mm phosphate, pH 7.5, 25 degrees C). 3-Cl HOPDA (t(12) = 504 h) was almost 3 times more stable than 4-OH HOPDA. Finally, 3-Cl, 4-Cl and 4-OH HOPDAs competitively inhibited the BphD-catalyzed hydrolysis of HOPDA (K(ic) values of 0.57 +/- 0. 04, 3.6 +/- 0.2, and 0.95 +/- 0.04 microm, respectively). These results explain the accumulation of HOPDAs and chloroacetophenones in the microbial degradation of certain PCB congeners. More significantly, they indicate that in the degradation of PCB mixtures, BphD would be inhibited, thereby slowing the mineralization of all congeners. BphD is thus a key determinant in the aerobic microbial degradation of PCBs.  (+info)

Relation between stillbirth and specific chlorination by-products in public water supplies. (4/131)

During water treatment, chlorine reacts with naturally occurring organic matter in surface water to produce a number of by-products. Of the by-products formed, trihalomethanes (THMs) are among the highest in concentration. We conducted a retrospective cohort study to evaluate the relationship between the level of total THM and specific THMs in public water supplies and risk for stillbirth. The cohort was assembled from a population-based perinatal database in the Canadian province of Nova Scotia and consisted of almost 50,000 singleton deliveries between 1988 and 1995. Individual exposures were assigned by linking mother's residence at the time of delivery to the levels of specific THMs monitored in public water supplies. Analysis was conducted for all stillbirths and for cause-of-death categories based on the physiologic process responsible for the fetal death. Total THMs and the specific THMs were each associated with increased stillbirth risk. The strongest association was observed for bromodichloromethane exposure, where risk doubled for those exposed to a level of [greater and equal to] 20 microg/L compared to those exposed to a level < 5 microg/L (relative risk = 1. 98, 95% confidence interval, 1.23-3.49). Relative risk estimates associated with THM exposures were larger for asphyxia-related deaths than for unexplained deaths or for stillbirths overall. These findings suggest a need to consider specific chlorination by-products in relation to stillbirth risk, in particular bromodichloromethane and other by-product correlates. The finding of a stronger effect for asphyxia deaths requires confirmation and research into possible mechanisms.  (+info)

Foetal growth and duration of gestation relative to water chlorination. (5/131)

OBJECTIVE: To assess the effect of exposure to chlorination byproducts during pregnancy on foetal growth and duration of pregnancy. METHODS: A population based study was conducted of 137,145 Norwegian children born alive in 1993--5. Information was obtained from the Norwegian medical birth registry, waterwork registry, and social science data service. The outcomes of interest were birth weight, low birth weight (<2500 g), small for gestational age, and preterm delivery (gestational age <37 weeks). The exposure assessment was based on quality of drinking water in the municipality where the mother lived during pregnancy. Municipal exposure was calculated with information on chlorination and the amount of natural organic matter in raw water measured as colour in mg precipitate/l. The main exposure category was high colour and chlorination, which was contrasted with the reference category of low colour and no chlorination. RESULTS: In logistic regression analysis adjusting for confounding, the risks of low birth weight (odds ratio (OR) 0.97, 95% confidence interval (95% CI) 0.89 to 1.06) and small for gestational age (OR 1.00, 95% CI 0.91 to 1.10) were not related to exposure. Contrary to the hypothesis, the risk of preterm delivery was slightly lower among the exposed than the reference category (OR 0.91, 95% CI 0.84 to 0.99). The risks of the studied outcomes were similar in newborn infants exposed to high colour drinking water without chlorination and chlorinated drinking water with low colour compared with the reference category. CONCLUSIONS: The present study did not provide evidence that prenatal exposure to chlorination byproducts at the relatively low concentrations encountered in Norwegian drinking water increases the risk of the studied outcomes.  (+info)

Chlorine dioxide inactivation of Cryptosporidium parvum oocysts and bacterial spore indicators. (6/131)

Cryptosporidium parvum, which is resistant to chlorine concentrations typically used in water treatment, is recognized as a significant waterborne pathogen. Recent studies have demonstrated that chlorine dioxide is a more efficient disinfectant than free chlorine against Cryptosporidium oocysts. It is not known, however, if oocysts from different suppliers are equally sensitive to chlorine dioxide. This study used both a most-probable-number-cell culture infectivity assay and in vitro excystation to evaluate chlorine dioxide inactivation kinetics in laboratory water at pH 8 and 21 degrees C. The two viability methods produced significantly different results (P < 0.05). Products of disinfectant concentration and contact time (Ct values) of 1,000 mg. min/liter were needed to inactivate approximately 0.5 log(10) and 2.0 log(10) units (99% inactivation) of C. parvum as measured by in vitro excystation and cell infectivity, respectively, suggesting that excystation is not an adequate viability assay. Purified oocysts originating from three different suppliers were evaluated and showed marked differences with respect to their resistance to inactivation when using chlorine dioxide. Ct values of 75, 550, and 1,000 mg. min/liter were required to achieve approximately 2.0 log(10) units of inactivation with oocysts from different sources. Finally, the study compared the relationship between easily measured indicators, including Bacillus subtilis (aerobic) spores and Clostridium sporogenes (anaerobic) spores, and C. parvum oocysts. The bacterial spores were found to be more sensitive to chlorine dioxide than C. parvum oocysts and therefore could not be used as direct indicators of C. parvum inactivation for this disinfectant. In conclusion, it is suggested that future studies address issues such as oocyst purification protocols and the genetic diversity of C. parvum, since these factors might affect oocyst disinfection sensitivity.  (+info)

Selective oxidation in vitro by myeloperoxidase of the N-terminal amine in apolipoprotein B-100. (7/131)

In contrast to the multiple low abundance 2,4-dinitrophenylhydrazine-reactive tryptic peptides formed by oxidation of LDL with reagent HOCl in vitro, myeloperoxidase-catalyzed oxidation produces a dominant product in considerably greater yield and selectivity. This modified peptide had a single amino-terminal sequence corresponding to amino acids 53-66 of apolipoprotein B-100 (apoB-100), but its mass spectra indicated a significantly higher mass than could be reconciled with simple modifications of this peptide. Subsequent studies indicate that this product appears to result from N-chlorination of the N-terminal amino group of apoB-100 and dehydrohalogenation to the corresponding imine, which may form the hydrazone derivative directly, or after hydrolysis to the ketone. The methionine residue is oxidized to the corresponding sulfoxide, and the primary sequence peptide (residues 1-14 of apoB-100) is linked by the intramolecular disulfide bond between C-12 and C-61 to the peptide composed of residues 53-66, as we have observed previously (Yang, C-Y., T. W. Kim, S. A. Weng, B. Lee, M. Yang, and A. M. Gotto, Jr. 1990. Proc. Natl. Acad. Sci. USA. 87: 5523-5527) in unmodified LDL. The selective oxidation by myeloperoxidase of the N-terminal amine suggests strong steric effects in the approach of substrate to the enzyme catalytic site, an effect that may apply to other macromolecules and to cell surface molecules.  (+info)

Water disinfection for international and wilderness travelers. (8/131)

Acquisition of waterborne disease is a substantial risk for international travelers to countries with inadequate sanitation facilities. It also poses smaller but still significant risks for wilderness travelers who rely on surface water in developed countries with low rates of diarrheal illness, such as the United States. This article reviews the etiology and risks associated with waterborne disease that might be encountered by both types of travelers. It also summarizes--and makes recommendations for--the various water-treatment methods available to travelers for reducing their risk of contracting waterborne disease.  (+info)

Bench-scale Cryptosporidium inactivation, pilot-scale disinfection by-product (DBP) formation and bench-scale inorganic DBP control experiments were conducted to evaluate the effectiveness of chlorine dioxide in meeting the current and future enhanced surface water treatment and disinfectant/disinfection by-product rules. A new chlorine dioxide generation process in which dilute, humidified chlorine gas is in contact with solid sodium chlorite was employed for this study. Chlorine dioxide was found to be effective in achieving CT values (pH=8 and temperature=20°C) of approximately 50 and 100 mg · min/l for 1-log and 2-log Cryptosporidium inactivation, respectively. Chlorine dioxide did not form significant amounts of trihalomethanes or haloacetic acids. Water spiked with high bromide concentrations resulted in insignificant amounts of organic DBPs after reaction with chlorine dioxide. Reaction of chlorine dioxide with water constituents resulted in the formation of chlorite and chlorate ions. ...

Influenza virus infection is one of the major causes of human morbidity and mortality. Between humans, this virus spreads mostly via aerosols excreted from the respiratory system. Current means of prevention of influenza virus infection are not entirely satisfactory because of their limited efficacy. Safe and effective preventive measures against pandemic influenza are greatly needed. We demonstrate that infection of mice induced by aerosols of influenza A virus was prevented by chlorine dioxide (ClO2) gas at an extremely low concentration (below the long-term permissible exposure level to humans, namely 0.1 p.p.m.). Mice in semi-closed cages were exposed to aerosols of influenza A virus (1 LD50) and ClO2 gas (0.03 p.p.m.) simultaneously for 15 min. Three days after exposure, pulmonary virus titre (TCID50) was 102.6±1.5 in five mice treated with ClO2, whilst it was 106.7±0.2 in five mice that had not been treated (P=0.003). Cumulative mortality after 16 days was 0/10 mice treated with ClO2 and 7/10

Chlorine dioxide and chlorite are characterized together for toxicity to reproduction because studies conducted with chlorite, the predominant degradation product of chlorine dioxide, are likely relevant to characterizing the toxicity of chlorine dioxide. In addition, studies conducted with chlorine dioxide may be relevant to characterizing the toxicity of chlorite. Chlorine dioxide is fairly unstable and rapidly dissociates, predominantly into chlorite and chloride, and to a lesser extent, chlorate. There is a ready interconversion among these species in water (before administration to animals) and in the gut (after ingestion). Therefore, what exists in water or the stomach is a mixture of these chemical species (i.e., chlorine dioxide, chlorite, chlorate) and possibly their reaction products with the gastrointestinal contents. Key study: Experimental results: The test procedure was: EPA OPP 83-3 (Prenatal Developmental Toxicity Study). Oral administration of sodium chlorite during ...

It should be noted that chlorine dioxide to ingest is a completely new antiviral approach as it is an oxidant and can eliminate by combustion any subspecies or mutant variant of virus. Given the emergency situation in which we currently find ourselves with Covid-19, the oral use of ClO2 is proposed immediately through a protocol already known and used.. 2. Toxicity: The biggest problems that arise with medications in general are due to their toxicity and side effects. New studies demonstrate its viability. Although the toxicity of chlorine dioxide in case of massive inhalation is known, there is no clinically proven death even at high doses by oral ingestion. The lethal dose (LD50, acute toxicity ratio) is considered to be 292 mg per kilogram for 14 days, where its equivalent in a 50 kg adult would be 15,000 mg administered for two weeks of a gas dissolved in water (something almost impossible). The oral sub-toxic doses used are around 50 mg dissolved in 100 ml of water 10 times a day, which is ...
Chlorine dioxide eliminates harmful microorganisms through a process called oxidation. All microorganisms are made up organic molecules such as proteins, polysaccharides and nucleic acids. Oxidation can denature proteins and other organic molecules in the walls and inside microorganisms. When their protective walls are disrupted and their metabolic machinery jeopardized, deadly microorganisms die. Chlorine dioxide is a powerful oxidizing agent. The term microorganism is a broad one. It includes bacteria, viruses and fungi. Even the walls of tough bacterial spores are organic in nature, and thus susceptible to the action of chlorine dioxide. Microorganisms do not have the inherent ability to counter chlorine dioxides oxidative attack. This leads us to the good news: microorganisms cannot develop resistance to chlorine dioxide. Since microorganisms are what create odors, chlorine dioxide effectively and permanently eliminates the odor at its source.. ...

Hello Hveragerthi, In the presence of UV light, chlorine dioxide breaks down to chlorine and oxygen. This does not take place in closed loop systems. The reason THM s are formed in the cooling systems of power plants is that the water is cooled in cooling towers that expose the chlorine dioxide in the water to UV light. This breaks down the chlorine dioxide to chlorine and oxygen, and the chlorine reaction forms THM s. It is significant that the EPA limit for THM concentration is 80 PPB. You will notice that chlorine, at 1 PPM produces around 65 PPB, whereas chlorine dioxide, a ...

MMS uses chlorine dioxide as an oxidizer. Hydrogen peroxide in my opinon is a much safer oxidizer and is more effective. Chlorine is actually a rather poor oxidizer. Reports in the Journal of Health form the 50s for example reported in one yaer over 80,000 cases of hepatitis transmission in chorinated drinking water. The chlorine compound used to disinfect water is chlorine dioxide. This is is why the more powerful oxidizers, such as ozone and potassium permaganate, are also used in water treatment these days since chlorine will not destroy many viruses in the presence of organic matter. ...
Chlorine disinfectants are effective against many common bacteria, viruses, parasites and fungi. A number of different commercial products are registered by the EPA for use in aquaculture as algicides and piscicides. Inorganic chlorine compounds include sodium hypochlorite and calcium hypochlorite. Sodium hypochlorite is available as a liquid, and calcium hypochlorite is available as HTH powder. HTH chlorine can form precipitates in the presence of some organics. Chlorine compounds are very corrosive to metal and harsh to human skin and mucous membranes. Their effectiveness depends on pH (optimal ~6 to 8) since much of the activity is attributed to the hypochlorous acid (HOCl) product. Very low concentrations can kill aquatic organisms, so the accidental exposure of nearby tanks is always a potential problem. Chlorine can be inactivated with sodium thiosulfate. One suggested ratio for inactivation is 7 mg of sodium thiosulfate to 1 mg of chlorine. Chlorine test kits should be used to make sure ...

In general, full brightness cannot be achieved in one bleaching stage, instead several consecutive stages must be used. Traditionally, bleaching has been done with chlorine-containing chemicals: with (elemental or gaseous) chlorine (C), hypochlorite (H) or with chlorine dioxide (D). Between stages, the dissolved lignin has been extracted with alkali. Typical traditional bleaching sequences were CEHDED and CEDED.. The principle was that the vast majority of the residual lignin was removed with the cheapest chemical i.e. chlorine, and only the final vestiges of lignin were removed with expensive chlorine dioxide.. When the transition was made to recycle bleach plant filtrates in order to reduce bleach plant wastewater effluent, the temperature of the chlorine stage began to rise, which had a detrimental effect on pulp strength. To prevent this, chlorine dioxide was added to the chlorine stage, i.e. the sequence used became (DC)EDED.. The pressurized reactor (EO) or pre-reactor (EO) have made it ...
Orthodontic patients, both adults and children, face dental hygiene challenges. Food trapped in braces provides a breeding ground for bacteria, often leading to gingivitis and bad breath. Plaque, a sticky biofilm of bacteria, can develop on teeth, tissue and brackets, inflaming gums. Braces can irritate the cheeks. Canker sores may even develop. In the case of lingual braces, placed on the inside of the teeth, the tongue may be irritated.. Orthodontists advise their patients to pay attention to homecare and visit their dentists frequently for checkups and cleaning. DioxiRinse Mouthwash is best known as a chlorine dioxide rinse for general dental homecare, but is particularly effective for orthodontic patients. DioxiRinse contains chlorine dioxide, a powerful oxidizing agent that provides a surprising combination of benefits.

This study investigated the reduction of ClO 2 - using a visible light (Vis) active photocatalyst, bismuth vanadate (BiVO 4 ). The effect of direct photolysis, the presence of oxalate, light source, and fluence on the reaction rate and by-product selectivity was evaluated. A commercial titanium dioxide (TiO 2 ) was used as a UV-benchmark comparison. Photolysis was an effective reductant of ClO 2 - , but it produced the undesirable byproduct chlorate (ClO 3 - ) and required ultraviolet light (UV) less than 360 nm. BiVO 4 and TiO 2 reduced ClO 2 - using irradiation greater than 360 nm, but ClO 3 - was also produced. ...

The kinetics and mechanism of the oxidation of methimazole (1-methyl-3H-imidazole), MMI, by chlorite in mildly acidic environments were studied. It is a complex reaction that gives oligo-oscillations in chlorine dioxide concentrations in excess chlorite conditions. The stoichiometry is strictly 2:1, with the sulfur center being oxidized to sulfate and the organic moiety being hydrolyzed to several indeterminate species. In excess MMI conditions over chlorite, the sulfinic acid and sulfonic acid were observed as major intermediates. The sulfenic acid, which was observed in the electrochemical oxidation of MMI, was not observed with chlorite oxidations. Initial reduction of chlorite produced HOCl, an autocatalytic species in chlorite oxidations. HOCl rapidly reacts with chlorite to produce chlorine dioxide, which, in turn, reacts rapidly with MMI to produce more chlorite. The reaction of chlorine dioxide with MMI is competitive, in rate, with the chlorite-MMI and HOCl-ClO2- reactions. This explains the

Chlorine is among one of the significant halogen compounds that has several uses. Sodium hypochlorite is called chlorine bleach and is used for water purification. Chlorine is also a part of sodium chloride, which is called table salt. Chlorine is very necessary for human life. Chlorine is considered the tenth substance that is abundantly present in the human body and the eleventh substance found abundantly on this planet. Chlorine is found to be helpful in saving many lives more than any other chemical as it is used as a disinfectant for most of the water supply in the United States as well as in other countries.. Chlorine is used in the synthesis of  most  pharmaceutical substances. The manufacture of almost all of the chemicals for crop protection is done by using chlorine. Chlorine is also found to be used in the synthesis of about 45 percent of commercial products.  The ocean, which is the result of the weathering of the continental lands, is the largest storehouse for salt. It has ...

The dangers of chlorination were first documented in the 1950s. During the Korean civil war, soldiers who were given chlorine tablets for their canteens developed severe cardiovascular diseases. A lot of soldiers died because of heart disease within the next ten years.. While you can do your best to avoid areas exposed to chlorine, an effective way to neutralize the toxic chemical is with ascorbic acid or vitamin C, since it chemically destroys chlorine. (Related: 7 Reasons why you should start eating more blueberries.). The reverse is also true since chlorine can destroy vitamin C. Since both chemicals cancel each other out, consuming more vitamin C than chlorine is crucial to neutralizing the latter.. One gram (g) of vitamin C can neutralize 100 gallons (gal) of water with one part per million (PPM) of chlorine. Take note that one PPM is standard for U.S. drinking water, but it can legally go up to four PPM chlorine.. While the naked eye cannot see the neutralization effect, as it is ...

Sodium bisulfate is formed by the partial neutralization of sulfuric acid, using either sodium hydroxide or sodium chloride. Like any acid, it should be handled with care.. Because chlorine can become unstable when exposed to ultraviolet light, most chlorine compounds added to pool water are stabilized. In some conditions, the pH of the water can then become too high. This results in scaly formations on the pool walls, floor and fixtures, as well as cloudy water. In addition, the chlorine is less effective. To prevent or counter these effects, dry acid or sodium bisulfite is added to the water. This balances the pH of the water.. To add dry acid to the pool, set the pump on filter. Dissolve the dry acid in a bucket of water, according to the manufacturer s instructions. Then pour the contents into the deepest part of the pool.. Like any acid, dry acid should be handled with care. Wear protective gear, including mask, goggles and clothing, while handling. Inhaling dry acid fumes can cause ...

Oxidation-reduction (redox) reactions are important in drinking water treatment and distribution. Oxidation-reduction potential (ORP) measurements of water reflect the tendency of major constituents in the water to accept or lose electrons. Although ORP measurements are valuable and can provide useful information toward protecting public health, they are not widely performed by the drinking water community for a variety of reasons. The objective of this research is to report the impact of five oxidants commonly used in drinking water as well as the pH on the measured ORP of water. Results show that the ORP of each oxidant system increased with increasing oxidant concentration to a maximum and decreased with increasing pH. Chlorine and chlorine dioxide waters had the greatest ORP followed by water containing monochloramine and permanganate, and water containing only oxygen. Duplicate ORP measurements revealed some inconsistencies with redox electrode measurements.. ...

Sodium chlorate is used as an oxidizing agent and bleach for paper pulp, to make chlorine dioxide used in water disinfection, in various manufacturing processes, and as a non-selective herbicide, defoliant, and harvest aid (Merck, 1996; HSDB, 1997; RTECS, 1997). This study was performed due to the potential for human exposure to sodium chlorate and the lack of pertinent developmental toxicity data.. Dose selection was based on a screening study in which New Zealand White rabbits were treated by gavage with 0, 100, 250, 500, 750, or 1000 mg sodium chlorate/kg body weight/day on gestational days 6 through 29 (NTP, 1998). Maternal toxicity was noted at greater than or equal to 250 mg/kg/day, with maternal morbidity and mortality at greater than or equal to 500 mg/kg/day. There was no definitive evidence of developmental toxicity at doses up to 500 mg/kg/day (NTP, 1998).. In this study, female NZW rabbits were dosed by gavage with sodium chlorate (100, 250, or 475 mg/kg/day) or its vehicle ...

  • Chlorine is a commonly used household cleaner and disinfectant. (
  • Hypochlorous acid (HOCL) is the most effective disinfectant in the chlorine family available in dilute solution. (
  • Two naturally occurring isotopes of chlorine exist, chlorine-35 and chlorine-36. (
  • Chlorine has two stable isotopes: Cl-35 and Cl-37. (
  • Chlorine found in nature is a mixture of these two isotopes. (
  • Chlorine gas was first produced by Swedish chemist Carl Wilhelm Scheele in 1774. (
  • Chlorine occurs commonly both in the Earth 's crust and in seawater. (
  • However, despite health hazards, chlorine is still commonly used to sterilize water and various products around the world. (
  • We can only do it for compounds containing cations that commonly bear more than one possible charge. (
  • The amount of residue of organic chlorine substances was measured by GC- MS. The result showed that the decomposition rate of trichloroethylene was 96% and that of 1, 1-dichloroethylene was 92% in the model. (
  • Any chlorine gas released at these sites would be quickly converted to other substances whose primary source may or may not have been chlorine. (
  • Several different chlorine odors can arise from various chlorine-based substances and in different circumstances. (
  • Most of the exposures involve chlorine or related substances. (
  • Despite recent advances, such as detergents derived from coconut and plastic polymers made of corn or soybeans, the industrial world's dependence on hazardous compounds hasn't changed much since World War II. (
  • Chlorine dissolves in water and is converted into chloride and hypochlorous acid. (
  • It can cause combustion with organic compounds, such as ammonia, turpentine, and natural gas . (
  • Monochloramine is typically formed in source water by first adding chlorine to break down any ammonia (into nitrogen and water) and then adding back trace amounts of ammonia in carefully monitored amounts to produce only monochloramine. (
  • Chlorine-based compounds are usually handled in water solutions, powders, or tablets, that are mixed with water before use. (
  • We attempted to characterize the dynamical changes in the levels of total organic carbon (TOC), AOX, chlorine and CHCl3 in a drinking water reservoir and in its tributaries, mainly at its spring, and attempt to relate the presence of AOX and CHCl3 with meteorological, chemical or biological factors. (
  • Chlorine changes from a gas into a liquid at a temperature of -34.05 ° C (-29.29 ° F) and from a liquid to a solid at -101.00 ° C (-149.80 ° F). The gas is soluble (dissolvable) in water. (
  • My 'home pool' (currently being renovated, for a reason) did dump its entire connected chlorine reserve into the pool when a sensor broke and the cleaning system decided that the pool water was being really dirty. (
  • A common misconception is that molecular chlorine (Cl 2 ) is present in chlorinated water. (
  • Chlorine compounds may be used to disinfect drinking water. (
  • This paper provides information on different areas where Ef-Chlor tablets containing NaDCC can act in an effective manner and could substitute the old methods, formulations and compounds still used for purifying water. (
  • Beacon chlorine free type amino acid compound powder fertilizer is a completely water soluble sulfuric acid type amino acid powder. (
  • It is also produced industrially as part of the "chlor-alkali" process in which both chlorine and sodium hydroxide (NaOH) are generated by applying electricity to salty water. (
  • Researchers have unveiled two new catalysts that have been designed with the effective treatment of tap water in mind, eliminating harmful chlorine compounds. (
  • Aside from pools, you can be exposed to chlorine in tap water. (
  • While tap water can be filtered, you're still in danger of chlorine exposure if you swim in pools. (
  • When a humidifier releases water into the air, it can also release chlorine gas. (
  • One gram (g) of vitamin C can neutralize 100 gallons (gal) of water with one part per million (PPM) of chlorine. (
  • Take note that one PPM is standard for U.S. drinking water, but it can legally go up to four PPM chlorine. (
  • When chlorine reacts to organic compounds in water, it produces trihalomethanes (THMs) that are considered environmental pollutants. (
  • The drying effects of chlorine and water may also cause itchiness without a rash. (
  • Since chlorite is an ionic compound, it will exist primarily in water. (
  • Indoor pools can be more problematic for people with respiratory conditions, for example, because compounds build up in the air above the water, and there's less natural sunlight, which breaks down some harmful compounds. (
  • Chlorine is used in water purification as well in the production of safe plumbing components constructed of polyvinyl chloride (PVC). (
  • Chlorine can be found in abundance in both the Earth's crust and in ocean water. (
  • Most chlorine gas for industry is produced by using electrolysis on water that contains dissolved sodium chloride (salt water). (
  • Health problems of swimmers in indoor pools have traditionally been attributed to the chlorine in the water. (
  • The reaction between chlorine and other elements can often be vigorous. (
  • Element X reacts with chlorine to form an ionic compound that has the formula XCl2. (
  • Even a one-minute rinse before diving in can remove much of the sweat and body gunk that reacts with chlorine. (
  • Dry skin, and smell of chlorine when your skin gets wet. (
