报告摘要：
Disinfection of drinking water is effective to prevent waterborne disease. However, an unintended consequence of the chemical disinfection process is the formation of disinfection byproducts (DBPs), resulting from reactions of disinfectants with natural organic matter in source water. Epidemiological studies have indicated potential association of chronic DBP exposure with adverse health effects (e.g. increased risk of bladder cancer). Although a few easily detectable DBPs are regulated, they may not be responsible for the adverse health effects. To date, majority of DBPs remain unidentified. To meet growing demands for safe drinking water, we must characterize DBPs that are important to human health effects. This presentation will describe our current research on targeted and nontargeted approaches using chromatography and high resolution mass spectrometry, in combination with machine learning techniques, to enhance characterization of precursors in source water and identification of new DPBs of toxicological importance. This research contributes to the improvement of water treatment process and protection of public health.
