摘　　要：对S区电镀厂地下水井水质中10种重金属和常规水质指标进行连续5年(2016—2020年)调查研究,利用单因子评价法和USEPA的水环境健康风险评价模型对研究区地下水中重金属对成人与儿童两人群人体健康产生的危害进行评估。结果表明,S区电镀企业地下水中重金属致癌物质引起的风险As的致癌风险水平成人主要集中在10^(-5)a^(-1),儿童主要集中在10^(-4)a^(-1),超过瑞典、荷兰、英国规定的最大可接受风险水平;接近ICRP规定的最大可接受水平,应引起重视,应作为风险决策管理的重点对象。Ten kinds of heavy metals and conventional water quality indexes in the water quality of the underground well of the electroplating plant in District S were investigated and studied for 5 consecutive years(2016—2020),and the harm of heavy metals in the groundwater of the study area to human health of adults and children was assessed by using the single factor evaluation method and the water environment health risk assessment model of USEPA.The results showed that the carcinogenic risk level of As caused by heavy metal carcinogens in the groundwater of electroplating enterprises in District S was mainly concentrated in 10^(-5) a^(-1) for adults and 10^(-4) a^(-1) for children,which exceeded the maximum acceptable risk level stipulated by Sweden,the Netherlands and the United Kingdom.The approach to the maximum acceptable level stipulated by ICRP should be taken seriously.It should be regarded as the key object of risk decision management.
