摘　　要：以2017年12月采集的淄博大武水源地的63件地下水样品有机物检测结果为依据,首先采用改进的潜在危害指数法在89项检测指标中确定了优先控制有机污染物,再利用健康风险评价模型进行了非致癌风险和致癌风险评价。研究结果表明:大武水源地地下水中优先控制的有机污染物为1,1,2-三氯乙烷、1,1-二氯乙烯等8种;地下水非致癌总风险值为[0~36.1],暴露人群患病潜在区域面积占研究区总面积的比例为18.6%;致癌总风险值为[0~4030],患癌的潜在区域面积占研究区总面积的比例为33.6%。饮水摄入为非致癌风险和致癌风险的主要暴露途径。大武水源地地下水有机污染的来源与石油化工企业的工业活动和城区人类活动有关,地下水有机污染高风险的分布区为齐鲁石化烯烃厂—西夏庄—金岭回族镇附近和临淄城区辛店街道东南。In order to analyze the characteristics of organic pollution in the groundwater, 63 pieces of groundwater samples were collected in Dawu water source in the Zibo City and 89 kinds of organic pollutants were analyzed in December 2017. The improved potential damage index method was used to determine the precedence-controlled organic pollutants, and the health risk assessment model was used to evaluate the health risks of the water in the area. Results show that the precedence-controlled organic pollutants in groundwater are trichloromethane, carbon tetrachloride, 1,1,2-trichloroethane and other 5 kinds of pollutants. The total non-carcinogenic risk of groundwater is between 0~36.1, and the proportion of the potential area of the exposed population to the total research area is 18.6%;the total risk of carcinogenesis is between 0-4030, and the proportion of potential area of cancer is 33.6%. Drinking water intake is the main exposure of non-carcinogenic risk and carcinogenic risk. The high-risk distribution areas of groundwater organic pollutants in Dawu water source were mainly distributed in the vicinity of Qilu Petrochemical Olefin plant(Hougao)-Xixia-Jinling Hui people Town where petrochemical enterprises gather and Xindian sub-district of Linzi urban area where human activities are frequent, indicating that the source of organic pollutants of groundwater is related to the industrial activities of petrochemical enterprises and urban human activities.
