采用吹脱捕集／固相萃取－气相色谱质谱法对某矿区6个煤矿的矿井水中有机物进行测试，并以美国国家环保局（U ．S ．EPA ）推荐使用的健康风险评价方法为依据，对该矿区矿井水有机污染的健康风险进行评价分析。结果表明：该矿区矿井水中主要的有机污染物为二氯甲烷、1，2－二氯乙烷、四氯化碳、苯和邻苯二甲酸二（2－乙基己基）酯5种；上述有机污染物的非致癌风险值均低于非致癌风险限值，但四氯化碳、1，2－二氯乙烷存在致癌风险，致癌风险值分别为5．54E－06，4．64E－06；各煤矿矿井水的非致癌风险值也均低于非致癌风险限值，但煤矿1和煤矿2的致癌风险超过限值，暴露受体长期接触这2个点位的水体，将影响暴露受体的健康。

In order to evaluate the health risk of mining water organic pollution ,organic pollutants from six mining water re-sources were detected by blow -off gathering/solid-phase extraction and then GC-MS ,and analyzed by health risks as-sessment model of contaminated sites recommended by U .S .EPA .The result showed that the main organic pollutants includ-ed dichloromethane ,sym-dichloroethane ,carbon tetrachloride ,benzene and di (2-ethylhexyl )phthalate;the non-car-cinogenic risk indexes of these organic pollutants were lower than risk limit ,but the cancer risk value of carbon tetrachloride and sym-dichloroethane exceeded the limit ,respectively being 5 .54E-06 and 4 .64E-06;the non-carcinogenic risk indexes of six mining water were lower than risk limit ,but cancer risks are existed in mine waters of the first and second coal mine and receptor being long -term exposure to the water would affect health of themselves .
