| 摘 要： | 通过对天津市宝坻区农村地下水水体中NH3-N,F,Hg,Pb,As和Cr6+浓度进行调查研究,应用美国环保局(EPA)推荐的健康风险评价模型对农村地下水水体中污染物引起的健康风险进行评价。结果表明,宝坻区农村,As通过饮水途径引起的致癌风险最大(1.8 10-5 a-1),通过饮水途径引起非致癌健康风险中F最大,NH3-N次之;致癌物质通过饮水途径所致健康风险远大于非致癌物质,但二者都低于国际防辐射委员会(ICRP)的推荐标准。

| Abstract: | This paper studies the concentration distributions of NH3 - N, F, Hg, Pb, As and Cr66＋ in six samples of rural drinking water in Baodi District by applying the heath risk assessment model recommended by US EPA to evaluate the health risks caused by the pollutants in the rural underground drinking water. Tile results showed that among the health risks caused by the carcinogens in rural drinking water, the largest risk is associated with As（ 1.8 × 106-5 a^-1 ）, among the health risks caused by the non - carcinogens in rural drinking water, the largest risk is associated with F, followed by NH3 - N. The health risks caused by the carcinogens in rural drinking water is much dangerous than the non - carcinogens, while both were lower than the maximum al- lowance levels recommended by ICRP. |
