本文根据有机物的挥发性对计算结果的影响大小,对U.S.EPA的健康风险评价模型进行适当改进,在模型中添加了污染物煮沸后的残留率TF项,评价分析了滹沱河冲积平原的健康风险。结果表明：（1）研究区典型的检出有机污染物为：三氯甲烷、四氯化碳、三氯乙烯和四氯乙烯,各采样点风险的主要贡献污染物为三氯甲烷和四氯化碳,主要的污染源应以工业和工业产品的使用污染为主;（2）对于非致癌风险和致癌风险,3种暴露途径的健康风险顺序均为：呼吸途径〉饮水途径〉皮肤接触途径;（3）非致癌风险中3个点均超过规定限值1.0,致癌风险中有4个点超过规定限值10~6;（4）使用和饮用开水并保持厂内工作车间和办公环境内空气畅通,可以在一定程度上降低健康风险。

In this paper,the health risk of the industrial zone in Hutuo river alluvial plain has been analyzed according to the impact for calculation results after Volatile Organic Compounds be boiled,and the Health Risk Assessment Model made by U.S.EPA has been improved appropriately.At the same time,the residual rate of TF after boiling has been added into the model.The results show that the typical detected organic pollutants in this area are chloroform,carbon tetrachloride,together with trichloroethylene and tetrachloroethene,they are mainly from industrial sources probably.secondly,as far as non-cancer risk and cancer risk are concerned,the health risks for three exposure pathways decrease as following order：inhalation pathway drinking water pathway and the dermal contact pathway;thirdly,there are three points exceeding the prescribed limit of 1.0 in non-carcinogenic risk,and four points exceeding the prescribed limits 10~6 in carcinogenic risk.The main contribution pollutants are chloroform and carbon tetrachloride.It＇s suggested to use and dlink boiled water,and to keep the air flow in workshop and work space in order to reduce health risks.
