Abstract: | Eight typical drinking water supplies in China were selected in this study. Both source and tap water were used to investigate the
occurrence of chlorinated disinfection byproducts (DBPs), and seasonal variation in the concentrations of trihalomethanes (THMs) of
seven water sources was compared. The results showed that the pollution level for source water in China, as shown by DBP formation
potential, was low. The most encountered DBPs were chloroform, dichloroacetic acid, trichloroacetic acid, and chlorodibromoacetic
acid. The concentration of every THMs and haloacetic acid (HAA) compound was under the limit of standards for drinking water
quality. The highest total THMs concentrations were detected in spring. |
