摘要
简要介绍了水环境健康风险评价模型,并根据北京市西城区水环境质量监测数据,对3个点位通过饮水途径引起的水环境健康风险进行了评价。结果表明,2003年-2012年,3个点位的水环境健康个人年风险多数超过国际辐射防护委员会(ICRP)推荐的最大可接受值,风险最大的是化学致癌物六价铬和砷,化学致癌物对人体健康危害个人年风险度远高于非致癌污染物,化学致癌物所致健康危害的个人年风险呈现波动降低趋势,非致癌污染物所致健康危害的个人年风险基本上保持稳定。
The environmental health risk assessment methods are briefly introduced. Based on water quality monitoring data, the water environmental health risk assessment model was employed to study the potential health risks brought by drinking from three sources of Xicheng District in Beijing. The results indicated that most of the overall individual annual health risks in the three water sources from 2003 to 2012 exceeded the standards recommended by ICRP, owing to over - high mass concentration of Cr（VI） and As. The health risks of carcinogens to individuals were much higher than those of non- carcinogens. The overall in- dividual annual health risks of carcinogens to individuals had a trend of decreasing and the risks of non - carcinogens to individuals remained stable in recent 10 years.
