- Abstract:
- Halogenated benzoquinones(HBQs) are a class of uncontrolled disinfection by-products that have been newly detected in recent years. Although the concentration of HBQs in water is very low with the level of ng/L, their cytotoxicity and genetic toxicity are both stronger than that of common disinfection by-products, e.g.trihalomethane, haloacetic acid, respectively. The high toxicity of HBQs and their risk on bladder cancer are undoubtedly a major threat to human health. The conventional treatment process of water treatment plants aims to remove the precursors of disinfection by-products, but there are few studies on the detection of HBQs and their precursors. The article summarizes the research progress of HBQs precursors from four aspects: the types of HBQs, the detection status of HBQs around the world, the proven precursors of HBQs and the pathways to generate HBQs, and the potential precursors of HBQs. It also summarizes the limitations of the current research on HBQs, and proposes new directions and ideas for HBQs research in future, hoping to provide a basis for a better HBQs processing, as well as analyzing the generation pathways of HBQs from the perspective of precursors.
