汾河太原段水环境健康风险评价

Discussion on Water Environment's Health Risk Assessment of Fenhe River's Taiyuan Section

为研究汾河太原段水环境污染对人体产生的健康危害风险,依据2001—2010年的水质监测数据,采用美国环保局(USEPA)推荐的健康风险评价方法,对汾河太原段主要污染物进行健康风险评价。结果表明:汾河太原段中化学致癌物Cr6+所致健康危害的潜在年风险值一直高于国际辐射防护委员会(ICRP)推荐的最大可接受风险水平,且Cr6+>As,应将Cr6+作为首要控制指标;与非致癌物相比,汾河太原段中化学致癌物为优先控制指标。

In order to study the health hazard risk caused by the water environment pollution on human body,this paper makes the health risk assessment on the major pollutants in Fenhe River＇s Taiyuan section based on water quality monitoring data from 2001 to 2010 and adopting the health risk assessment methods recommended by U.S.Environmental Protection Agency （USEPA）.The results show that the potential annual risk value of health risk caused by chemical carcinogen Cr6＋ is always higher than the maximum acceptable risk level recommended by the International Commission on Radiological Protection （ICRP）,and Cr6＋ is larger than As,so Cr6＋ should be taken as the primary control index;compared with non-carcinogens,the chemical carcinogens in Fenhe River＇s Yaiyuan section is taken as a priority control index.
