Trihalomethanes were the subject of the first drinking water regulations issued after passage of the U.S. Safe Drinking Water Act in 1974. [ 5 ] The EPA limits the total concentration of the four chief constituents ( chloroform , bromoform , bromodichloromethane , and dibromochloromethane ), referred to as total trihalomethanes (TTHM), to 80 ...
The chloroform molecule can be viewed as a methane molecule with three hydrogen atoms replaced with three chlorine atoms, leaving a single hydrogen atom. The name "chloroform" is a portmanteau of terchloride (tertiary chloride, a trichloride) and formyle, an obsolete name for the methylylidene radical (CH) derived from formic acid. [citation ...

The main problems with this method are that it cogenerates HCl and it produces mixtures of different products. Using CH 4 in large excess generates primarily CH 3 Cl and using Cl 2 in large excess generates primarily CCl 4, but mixtures of other products will still be present. Halogenation of methanol. This method is used for the production of ...
Bromoform can be absorbed into the body by inhalation and through the skin. The substance is irritating to the respiratory tract, the eyes, and the skin, and may cause effects on the central nervous system and liver, resulting in impaired functions. Its LD 50 is 7.2 mmol/kg in mice, or 1.8 g/kg. The International Agency for Research on Cancer ...
Disinfection by-products (DBPs) are organic and inorganic compounds resulting from chemical reactions between organic and inorganic substances such as contaminates and chemical treatment disinfection agents, respectively, in water during water disinfection processes.

Bromodichloromethane is a trihalomethane with formula C H Br Cl 2.It is a colorless, nonflammable liquid which will dissolve in water, or evaporate in air. [1] Most of the chemical is produced through the chlorine disinfection process, [1] and as a result it can occur in municipally-treated drinking water. [2]
