摘　　要： 采用美国环境保护署(US EPA)推荐的水环境健康风险评价模型,结合水环境质量监测资料,对惠州市不同水源地进行了健康风险评价,分析惠州市饮用水源地污染物的分布特征与风险水平。计算结果表明,个人化学致癌物总年风险远大于非致癌物总年风险,对人体有健康风险的污染物主要是化学致癌物;2008～2010年惠州市各饮用水源地水环境健康个人总年风险均超过国际辐射防护委员会(ICRP)推荐的标准,主要原因是化学致癌物Cr6+的质量浓度相对较高,加强治理和控制化学致癌物特别是Cr6+是降低饮用水源地水环境健康风险的有效途径。 By using the water environment health risk assessment model from EPA （Environmental Protection Agency, US）, and combining with water environment quality monitoring data, the health risk for drinking water source in Huizhou City was evaluated, the distribution char- acteristies anf risk level of pollutants in drinking water sources were analyzed. The results showed that the main hazardous pollutants were chemical carcinogens. The health risks of carcinogens to individuals were much higher than those of non-carcinogens. The overall individual annual health risks in the six drinking water sources from 2008 to 2010 all exceeded the standards recommended by ICRP. Therefore, strength- ening of carcinogens control, especially Cr, is an effective way to reduce the health risks in drinking water sources.
