摘要
随着工农业不断地发展,地下水有机污染问题日益严重。同时,有机污染对人体健康可能造成的威胁逐渐被重视。通过对细河周边地下水进行调查,采样测试,初步了解了沈阳市细河周边地下水有机污染现状并确定特征污染物。利用U.S.EPA推荐的健康风险评价方法确定在饮水、皮肤接触途径下特征污染物的暴露量,并定量表征其健康风险指数和总致癌风险。评价结果显示,越靠近细河,地下水中有机污染可能造成的健康风险越高;沿细河上游至下游,两岸地下水中有机污染健康风险由高变低。
With the development of agriculture and industry, the the same time, the health risk resulted from organic contaminat problem of groundwater organic pollution is increasingly serious. At e had been gradually paid more attention. Based on the investigation and sampling of the groundwater around Xi River, the characteristics of groundwater organic pollution is analyzed and C6H6C16 is chosen as the representive organic pollutant in the health risk assessment. The method of health risk assessment recommended by US EPA is used to calculate the exposure dose of different exposure pathways, such as drinking or contacting with skin, the health risk index and total carcinogenic risk. The assessment results indicate that the higher health risk of shallow groundwater occurs in the nearby of the Xi River whereas the health risk decreases from the upstream to the downstream.
