报告摘要：

Appropriate disinfection of drinking water is effective to prevent waterborne disease. An unintended consequence of the chemical disinfection process is the formation of disinfection byproducts (DBPs), resulting from reactions of disinfectants with 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 meet growing water demands while controlling regulated DBP formation, water utilities are applying new disinfectant combinations. In light of these changes in disinfection practice, we must characterize DBPs that are important to human health effects. This presentation will describe our current research on identifying new DBPs of toxicological importance and their precursors using targeted and nontargeted approaches, understanding the formation of new DBPs, and characterizing toxicity of the identified new DBPs.
