摘　　要：对铜陵矿区周边尾砂样、土壤、地表水、浅层地下水等样品进行野外采集。采集了163个样品,对样品中11种重金属元素进行了测试,并对测试结果进行了统计分析,探明了铜陵矿区周边不同环境介质中重金属的含量分布特征。结果表明金属矿所产生的尾砂是各种重金属的主要富集介质;矿区土壤污染的主要重金属类型是As、Zn、Pb、Cd、Cu,均高出三类标准7倍以上;民井地下水主要是Zn、Pb污染,超标率分别达到2.6%、2.6%。163 samples of tailing sand,soil,surface water and shallow groundwater around Tongling mining area are collected in the field.11 kinds of heavy metal elements in the samples are tested,and the statistical analysis has been carried out in this paper.It explores the concentration distribution characteristics of heavy metals in different environmental media in the surrounding area of Tongling mining area.The results show that the tailing sand produced by the metal is the main all kinds of heavy metal enrichment medium;the main heavy metal types of soil pollution in mining areas are As,Zn,Pb,Cd and Cu,which are more than 7 times higher than the three standards.The groundwater of civilian wells is also polluted by heavy metals,mainly Zn and Pb,with the exceeding rate reaching 2.6%and 2.6%respectively.
