上海某地区饮用水源地水环境健康风险评价

摘要

水环境健康风险评价就是把水环境污染与人体健康定量联系起来的一种新的评价方法。应用美国环保局推荐的健康风险评价模型对上海某地区4个主要饮用水源地经饮水途径所致的健康风险进行评价。结果显示，2007年至2011年，化学致癌物所致的健康风险远大于非致癌污染物，主要风险因子为化学致癌物中的六价铬，应将其作为首要的环境健康风险管理控制指标。%Health risk assessment of water environmental is a new assessment method which quantificationally connects water pollutants with human health.Based on the health risk assessment models recommended by US .EPA, the risks of some pollutants in the main 4 drink-ing water sources in a suburban of Shanghai are assessed .The results indicated that the health risks of carcinogens were much higher than those of non-carcinogens.The main factor was Cr(Ⅵ).Therefore, it may be defined as the priority of controlled pollutants .
