[Study advance and control measure on disinfection by-products in drinking water].
The related studies on the chemistry, toxicology, epidemiology, distribution level, hygienic standard or maximum contaminant level and control measure were summarized. The results showed that a lot of disinfection by-products (DBPs) formed during chlorination and trihaloromethanes (THMs) and haloacetic acids (HAAs) were the two major groups of found in drinking water. From the present knowledge and health effects, the DBPs of most interest are THMs, HAAs, bromate and chlorite. The hygienic standard or maximum contaminant level of drinking water have been revised or supplemented. In order to decrease the chemical risk due to DBPs without compromising microbiological quality, the monitor parameters have been increased and maximum contaminant levels of the parameters have been controlled strictly.
