摘　　要：总结了壬基酚、双酚A、阿特拉津、多氯联苯和雌激素等典型内分泌干扰物(EDCs)在饮用水消毒过程中的去除效果以及副产物的生成情况,分析了由此引起的内分泌干扰作用及其毒性变化。典型EDCs母体在消毒过程中均有一定程度的降解,并以多种途径生成了不同的消毒副产物,依母体结构和消毒方式的不同,最后表现的毒性会有不同程度的改变,其中双酚A消毒后的产物毒性将大大增加。因此研究饮用水中EDCs在消毒工艺中的降解特性和物质迁移变化,对指导饮用水消毒的运行和管理具有重要意义。The removal effect and the byproducts formation of typical endocrine disrupting chemicals （EDCs） including nonylphenols, bisphenol A, atrazine, polychlorinated biphenyls, estrogen and so on in the drinking water disinfection process were summarized. The variation of resulting effect and toxicology of endocrine disruptor were analyzed. Some typical EDCs can be degraded to some degree and transformed to certain byproducts in many pathways during the disinfection processes. The Variation of the toxicity relies on the differences of precursor structures and disinfection methods. The toxicity of bisphenol A byproduct is increased greatly after disinfection. Therefore, the research on degradation performance and transformation of EDCs in the operation and management drinking water disinfection process is very significant for the direction of of drinking water disinfection.
