tri·hal·o·meth·ane

 (trī′hăl-ə-mĕth′ān′)
n.
Any of several chemical compounds in which halogen atoms replace three of the hydrogen atoms normally present in a methane molecule. These toxic compounds can occur in chlorinated water as a result of reaction between organic materials in the water and chlorine added as a disinfectant.

trihalomethane

(traɪˌheɪləʊˈmiːθeɪn)
n
(Chemistry) a type of chemical compound in which three of the hydrogen atoms in a methane molecule have been replaced by halogen atoms, esp by chlorine in drinking water. Trihalomethanes are thought to be carcinogenic

The THMs include chloroform, bromoform, bromodichloromethane, and dibromochloromethane.

When chlorine comes into contact with organic matter it can form compounds known as trihalomethanes (chloroform, bromoform, dibromochloromethane, and bromodichloromethane).
They were prepared in iso-octane for chloroform and n-pentane for bromoform, bromodichloromethane and dibromochloromethane.
The authors report that concentrations of ETHM [sum of chloroform (TCM), bromodichloromethane (BDCM), dibromochloromethane (DBCM), and bromoform (TBM)] in both blood and water varied by site and season.
The VOCs found in this survey were chloroform, methyl-tertiary butyl ether, trichloroethylene, isopropyl ether, dibromochloromethane, 1,1,1-trichloroethane, and cis-1,2 dichloroethylene.
RESULTS: Blood [summation over (term)]THM [sum of chloroform (TCM), bromodichloromethane (BDCM), dibromochloromethane (DBCM), and bromoform (TBM)1 concentrations varied by site and season.
The four THMs are chloroform, bromoform, bromodichloromethane, and dibromochloromethane.
Trihalomethanes (THMs) are the DBPs found generally at the highest concentrations, and the most common THMs are chloroform, bromodichloromethane, dibromochloromethane, and bromoform.
