"Elimination of radioactivity in urine and feces equaled 20, 33, and 48% of the total dose for the low, medium, and high doses, respectively. Chlorate and chloride were the only radioactive chlorine species present in urine; the fraction of chlorate present as a percentage of the total urine radioactivity decreased with time regardless of the dose. Chloride was the major radioactive residue present in edible tissues, comprising over 98% of the tissue radioactivity for all animals. Chlorate concentrations in edible tissues ranged from nondetectable to an average of 0.41 ppm in skeletal muscle of the high-dosed animals. No evidence for the presence of chlorite was observed in any tissue. Results of this study suggest that further development of chlorate as a preharvest food safety tool merits consideration."

Incidents like this, which create **chlorine** gas, occur more than 2,000 times per year in the US

"Eleven healthy volunteers were exposed to 0 (clean air), 0.5 and 2.2 ppm for 2hours"

[Old - 1984?] Isopropyl alcohol is manufactured in the United States by an indirect hydration technique in which a fraction containing 40-60% propylene that is isolated from refinery exhaust gases reacts with sulfuric acid (Lowenheim and Moran, 1975). In an older (strong-acid) process, 88-93% sulfuric acid reacted with propylene gas at 25-60°C for a long time. In a newer (weak-acid) process, which has replaced the strong-acid process, propylene gas is absorbed in 60% sulfuric acid at 85°C for a short reaction time (NIOSH, 1976). Estimated annual production capacity for 1981 was 2.8 million pounds (SRI, I...

"Oxidative stress is the result of the imbalance between reactive oxygen species (ROS) formation and enzymatic and nonenzymatic antioxidants. Biomarkers of oxidative stress are relevant in the evaluation of the disease status and of the health-enhancing effects of antioxidants." "The clinical significance of biomarkers of oxidative stress in humans must come from a critical analysis of the markers that should give an overall index of redox status in particular conditions."

The current situation in India regarding the COVID-19 pandemic is the worst since its first detection, in terms of the number of new cases per day, and it is now more than 10000 (as of June 7, 2020). In addition to several precautionary steps being taken (social distancing, use of masks, sanitizing hands etc.), spraying disinfectants (NaOCl solution) over several residential, official and commercial buildings, open areas, markets, public road transports, railways etchas been occurring on a regular basis. It has also cometo the world’s attention that spraying of disinfectants has been especially used on people who are migrating from one part of the country to another. In this letter, I have made an attempt to discuss some major impacts of NaOCl on human health as well as atmospheric chemistry. NaOCl once emitted into the air reacts easily with the water vapor to form HOCl that further gets photo-dissociated into various reactive species. These reactive species have significant potentials to participate in various tropospheric chemistry of chlorine radical, ozone, S (IV) oxidation, hydrocarbon oxidation, modification of chloride salts etc. I have also recommended some important steps to be taken if spraying of NaOClis deemed essential.

Over the past 10 years, there have been hundreds of accidents involving chlorine nationwide, injuring thousands

The first building block is carboxyl benzoate which is found naturally in cranberries. Carboxyl benzoate is widely used as a preservative in many foods and drinks and generally recognized as a safe compound. Two arms are made out of cysteamine (found naturally in meat and on the terminal end of Co-enzyme A) which is also a widely used natural antioxidant. The cysteamines have a sulfhydryl (-SH) at their terminal ends, and the amino ends are attached on the 1st and 3rd carbon groups of the carboxyl benzoate. This allows the -SH groups to flex, rotate and take many different positions to accommodate the binding parameters of several toxic metals that are attracted to -SH groups, which covers most toxic heavy metals.
