伊通河水环境健康风险评价

The Water Environmental Health Risk Assessmentof Yitong River

根据2006年吉林省水环境检测资料,针对水体中污染物质经饮水途径对人体的健康危害风险进行分析与评价。结果表明:水体中化学致癌物质对人体健康危害的风险较大,砷和镉对人体的致癌风险均超过5×10-5,即U.S.EPA的致癌风险评价指南中推荐的人体年风险最大可以接受的风险值,危险程度极高。另外,4类非致癌物对人体健康危害风险较小,其健康风险排列由高到低顺序为氟化物>氨氮>铜>挥发酚。结论揭示了该河段水质的健康风险水平,对伊通河水源健康管理与保护措施的制定有一定的参考价值。

According to the 2006 information on the detection of water environment in Jilin province, which is against contaminants in water through water channels on human health hazard analysis and risk assessment. Results indicate that the pollutants of chemical carcino- gens risk less harm to human health but more obviously, arsenic and cadmium exceed human in risk acceptable value 5 x 10 - 5 every year that U. S. EPA recommended guide of carcinogenic risk assessment of carcinogenic ,. The degree of risk is extremely high. Four non - carci- nogenic risks health less, The order from high to low risk their health for fluoride 〉 ammonia 〉 copper 〉 volatile phenols. Findings reveal the health risk level of the River, it is valuable for Yitong River water resources health management and protection measures.
