摘要
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 resources were detected by blow- off gathering / solid- phase extraction and then GC- MS,and analyzed by health risks assessment model of contaminated sites recommended by U. S. EPA. The result showed that the main organic pollutants included dichloromethane,sym- dichloroethane,carbon tetrachloride,benzene and di（ 2- ethylhexyl） phthalate; the non- carcinogenic 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.
