生活饮用水中卤代苯醌的形成和毒性研究进展

Formation and toxicity of halobenzoquinones in drinking water:a review of recent studies

卤代苯醌(HBQs)是一类新型未受控饮用水消毒副产物,其细胞毒性和遗传毒性较一些受控消毒副产物更强,还具有生殖发育毒性。鉴于长期暴露HBQs可能产生潜在健康风险,故对目前饮用水中HBQs的形成和毒性研究进展进行了综述,拟为将来对HBQs进行健康风险评估和制定饮用水卫生标准提供科学依据。

Halobenzoquinone（HBQs） is a kind of emerging and unregulated disinfection by-products in drinking water. The cytotoxicity and genotoxicity of HBQs are much higher than some regulated disinfection by-products. HBQs also have reproductive and developmental toxicity. Long-term exposure to HBQs may produce potential health risks. The research progress of current study on formation and toxicity of HBQs in drinking water were summarized in the present paper to provide scientific evidence for health risk assessment and establishment of standards for drinking water quality.
