摘　　要：为探讨废铅蓄电池暂存地周边土壤环境质量现状,以长三角地区4家典型废铅蓄电池回收暂存企业为研究对象,对其周边土壤进行布点取样,分析了铅、砷、镉、六价铬、铜、汞、镍、锑8种元素含量,并以单因子污染指数法、内梅罗综合污染指数法及潜在生态风险指数法对土壤重金属污染状况进行了评价。单因子污染指数及内梅罗综合污染指数评价结果表明,本次调查企业周边土壤污染等级均为安全;潜在生态风险指数评价结果表明,企业周边土壤中Cd的单项潜在生态风险等级较高,各企业场地周边土壤综合潜在生态风险程度为轻微至中等范畴。分析结果可为开展专门性的监测工作提供决策依据和技术支持。To investigate the current status of soil environmental quality around temporary storage sites for waste lead batteries,four typical enterprises in the Yangtze River Delta region were selected as the research objects.Soil samples were collected and analyzed for eight elements:lead,arsenic,cadmium,hexavalent chromium,copper,mercury,nickel,and antimony.Single-factor pollution,Nemero comprehensive pollution,and potential ecological risk indices were used to evaluate the soil’s heavy metal pollution status.The evaluation results of the single-factor pollution and Nemero comprehensive pollution indices revealed that the pollution level of the soil surrounding the investigated enterprises was safe.The evaluation results of the potential ecological risk index showed that the individual potential ecological risk level of cadmium in the soils around the storage sites was relatively high,whereas the comprehensive potential ecological risk level of the soil around each site was mild to moderate.The results of the analysis will aid in decision-making and provide technical support for specialized monitoring.
