Where are trihalomethanes found?
Primary sources of DBPs are chlorinated drinking water and recreational water bodies, such as swimming pools.
How are THMs formed?
THMs are formed in drinking-water primarily as a result of chlorination of organic matter present in raw water supplies. The rate and degree of THM formation increase as a function of the chlorine and humic acid concentration, temperature, pH, and bromide ion concentration (Stevens et al., 1976; Amy et al., 1987).
Where does total trihalomethanes come from?
Trihalomethanes (THMs) are a byproduct of the water treatment process. They are formed when natural organic material, such as the decaying vegetation commonly found in lakes and reservoirs, reacts with chlorine used to treat the water. This reaction produces “disinfection byproducts,” the most common of which are THMs.
What is the origin of THMs in treated water?
THMs are trihalomethanes, chemical compounds that can be formed when water is disinfected with chlorine. THMs occur when chlorine reacts with organic matter in water, and for this reason are more common in surface water supplies throughout Canada.
What is Dibromochloromethane used for?
Dibromochloromethane (Chlorodibromomethane) was used in the past to make other chemicals such as fire extinguisher fluids, spray can propellants, refrigerator fluid, and pesticides. It is now only used on a small scale in laboratories.
What is the chemical formula for Dibromochloromethane?
CHBr2Cl
Dibromochloromethane/Formula
Where does dibromochloromethane come from in drinking water?
Dibromochloromethane is also a disinfection byproduct, formed by the reaction of chlorine with natural organic matter and bromide ions in the raw water supply. As a result, it is commonly found in chlorinated drinking water.
Why is dibromochloromethane used as a reagent?
Today it is used only as a laboratory reagent. Dibromochloromethane is also a disinfection byproduct, formed by the reaction of chlorine with natural organic matter and bromide ions in the raw water supply. As a result, it is commonly found in chlorinated drinking water. Also, it is able to reduce methane production in ruminants by 79 %.
