摘    要:介绍了水环境健康风险评价方法,并根据太湖饮用水源地水环境质量监测数据,对4个饮用水源地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,2005~2009年,4个饮用水源地水环境健康个人年风险多数超过国际辐射防护委员会(ICRP)推荐的标准,主要风险因子为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化学致癌物;化学致癌物所致健康危害的个人年风险呈波动降低变化,非化学致癌物所致健康危害的个人年风险基本保持稳定。

关 键 词:太湖  饮用水源地  健康风险评价

Abstract:The assessment methods for environmental health risk is introduced in water environment.Based on water quality monitoring data,the water environmental health risk assessment model of EPA was employed to study the potential health risks brought by drinking from four drinking water sources of Taihu lake.The results indicated that most of the overall individual annual health risks in the four drinking water sources from 2005 to 2009 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;and,the overall individual annual health risks of carcinogens to individuals had a trend of decreasing and the risks of non-carcinogens to individuals remained stable in recent 5 years.
Keywords:Taihu lake  Drinking water source  Health risk assessment
