General description

Bromodichloromethane (BDCM) is the most common trihalomethane (THM). It is a disinfection by-product identified in drinking water after chlorination, which appears to be carcinogenic and toxic. THMs are not only found in drinking supplies but are also prevalent in swimming pools, dump sites and fish samples.

Application

Bromodichloromethane may be used as an analytical standard for the determination of the analyte in drinking water and chlorinated seawater samples by chromatography techniques.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Trihalomethanes in drinking water have been associated with higher occurrence of small-for-gestational-age (SGA) births, although results have been inconsistent. We geocoded residential address for mother of live, singleton, term births to 33 water distribution systems in a large metropolitan area
