摘要
对海口市集中式饮用水源地水体中Cd、As、Hg和Pb含量进行测定和健康风险评价。研究表明:4种元素在水中浓度较低,均优于《地表水环境质量标准》(GB3838-2002)二级标准。采用USEPA推荐的健康风险评价法对平均个人年健康致癌风险和非致癌风险进行评价,4种元素的风险值基本在10-10a-1,通过饮水途径产生的风险指数低于美国环保局的推荐值。
In order to understand the drinking water safety risk and to further environmental protection work. The concentrations of Cd, As, Hg and Pb and the health risk in centralized drinking water sources in Haikou were studied.The results indicated that the concentration of the four elements were better to the level two of Environmental Quality Standards for Surface Water in China （GB3838-2002）. The Health Risk Assessment of USEPA was applied to evaluate the value of the average personal health carcinogenic risk and non-carcinogenic risk were 10-10a-1, less than the United States Environmental Protection Agency＇s recommental value.
