摘　　要：为了评价南方某城市供水管网中氯化消毒副产物对人体健康产生的潜在危害,对该市全线供水管网中的三卤甲烷和卤乙酸质量浓度进行检测,并采用美国环境保护署（US EPA）的健康风险评价方法,对管网水体中氯消毒副产物通过食入、皮肤接触和呼吸吸入3种途径进入人体的危害进行了风险计算和初步评价。结果表明：管网水体中消毒副产物对人体健康产生的致癌风险最大值为4.32×10-5,在美国环境保护署（US EPA）可以接受的限值（10-6~10-4）内,不会对人体产生明显的健康危害。In order to assess the potential health risk to human beings caused by chlorinated disinfection byproducts（DBPs）in water distribution network in a southern city,the concentrations of THMs and HAAs in drinking water from the centralized water supply systems were detected in this paper,and assessment of the health risks invited by three exposure pathways（i.e.oral ingestion,dermal absorption and inhalation exposure）was performed through a method of US EPA.The results showed that the maximum cancer risk within the area of water supply pipe network was 4.32×10-5,which met the needs of US EPA（10-6—10-4）as well as harmless for people.
