摘　　要：地下水水质直接影响着人们的健康.为了解辽阳市某化工生产区地下水水质状况,对其进行检测,并采用美国国家环保署(US EPA)水环境健康风险评价模型,对该地区地下水水质中化学致癌物和非化学致癌物进行分析评价.结果表明:该化工生产区地下水水质健康风险主要来自致癌性污染物,占全年总致癌风险99.05%.建议加强对水源地致癌物质的监测与防控,同时也要高度重视面源污染的治理.Groundwater quality affects people′s health directly.In order to understand and test the status of groundwater water quality in a chemical production area in Liaoyang,this paper analyzed and evaluated the chemical carcinogens and non chemical carcinogens in the groundwater of the region by adopting the US EPA water environmental health risk assessment model.The results showed that the health risk of groundwater quality in this chemical production area mainly comes from carcinogenic pollutants,accounting for 99.05% of the total carcinogenic risk in the whole year.It is suggested to strengthen the monitoring and prevention of the carcinogenic substances in water source areas,and pay high attention to the governance of non-point source pollution.
