///Based on the Health Risk Assessment Model made by U.S.EPA, the authors analyzed and evaluated the health risk of groundwater organic pollution at an abandoned chemical plant. The results show that the typical organic pollutants in this plant include 1, 2-Dichloropropane, benzene, Toluene, Chloroform. Secondly, non-cancer risk and cancer risk are concerned, the health risks for three exposure pathways decrease as following order: inhalation, drinking water and the derma contact. 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, which are unacceptable. It’s suggested that keeping the air flow in living environment can reduce health risk to a certain extent.
