摘　　要：采用美国环保署(USEPA)推荐的健康风险评价模型,评估了我国某市居民因饮用水消毒副产物三卤甲烷(THMs)而产生的健康风险。通过对经口摄入、皮肤接触和蒸汽吸入3个途径下THMs暴露的终生致癌风险和危险指数进行计算。结果表明,经口摄入是引起致癌风险和非致癌风险的最主要途径。但是其他两种途径的风险也是不可忽视的。This work assessed the human health risk from trihalomethanes （THMs） in drinking water of a certain city in China, using the risk assessment models developed by the United States Environmental Protection Agency （USEPA）. The lifetime cancer risk and risk index of THMs through three exposure pathways （i. e. oral ingestion, dermal absorption and inhalation exposure） from tap water in six districts of this city were calculated. The results showed that oral ingestion was the major exposure pathway of THMs and brought on the highest risk of cancer for inhabitant. However, dermal absorption and inhalation were also not ignored.
