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(Chemistry) a type of chemical compound in which three of the hydrogen atoms in a methane molecule have been replaced by halogen atoms, esp by chlorine in drinking water.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 four THMs in drinking water that are regulated in the United States, European Union, and other countries are chloroform, bromodichloromethane, dibromochloromethane, and bromoform; these chemicals display different physicochemical and toxicological properties.
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).
THMs [comprising chloroform, bromodichloromethane (BDCM), dibromochloromethane (DBCM), and bromoform] are the most prevalent class in drinking waters, followed by HAAs (comprising bromo-, chloro-, dibromo-, dichloro-, tribromo-, trichloro-, bromochloro-, bromodichloro-, and dibromochloro-acetic acids) (Krasner et al.
They were prepared in iso-octane for chloroform and n-pentane for bromoform, bromodichloromethane and dibromochloromethane.
Trihalomethanes (THMs) are the most abundant DBP class in drinking water; they include chloroform (TCM), bromodichloromethane (BDCM), dibromochloromethane (DBCM), and bromoform (TBM) (Nieuwenhuijsen et al.
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.
