Chlorination is a primary method of disinfection of water supplies worldwide. The presence of natural natural organic matters (NOM), also known as "DBP precursors", react with the residual chlorine and form various types of disinfection by-products (DBPs) in the drinking water systems. More than 500 DBPs have been reported in the scientific literature but the trihalomethanes (THMs) and haloacetic acids (HAAs) are the two largest groups of DBPs in chlorinated water. Long term exposure to DBPs at levels higher than the specified regulatory limit is harmful to human health.

氯化是世界范围内供水消毒的主要方法。天然有机物（NOM）的存在，也称为“DBP前体”，与余氯反应，在饮用水系统中形成各种消毒副产物（DBPs）。科学文献中报道的DBPs超过500种，但三卤甲烷（THMs）和卤乙酸（哈斯）是氯化水中最大的两类DBPs。长期暴露于高于规定水平的消毒副产物 监管限制对人体健康有害。
