摘要
本论文以安庆市9个饮用水源地作为健康风险评价对象,选取2005～2008年的部分水质资料,运用健康风险评价模式,结合安庆地区人群状况修正部分参数,对该地区9个水源地经饮水途径造成的健康风险进行计算和评价。结果表明：化学致癌物所致的健康风险远远高出非致癌物,水源地健康风险主要来源于化学致癌物,在所评价的水源地中以铬（六价）的风险值最大,且有8个水源地铬（六价）的风险值均超过国际辐射防护委员会推荐的最大可接受风险水平,最高值出现在花凉亭水库。
In this paper,based on data of water quality observed during 2005～2008,the health risks caused by drinking water in nine drinking water supply sources of Anqing city were assessed adopting concerned mathematical model and revised with conditions of the local people.The results showed that the health risks of nine drinking water supply sources were mainly caused by the chemical carcinogens which were significantly higher than those of non-carcinogens.Comparably the risk values of Cr was the maximum in all drinking water supply sources in which eight sources were higher than the maximum acceptable level recommended by ICRP.The maximal risk value of Cr was from Hualiangting Reservoir.
