摘　　要：安徽铜陵狮子山铜矿杨山冲尾矿库始建于1966年,1991年停用。本文调查了尾矿库及其周边的重金属元素地球化学状况,以环境介质(土壤、水和植物)中的重金属元素含量作为研究对象,分别采集了尾矿库内、毗邻尾矿库农田和远离尾矿库土壤、植物的样品,以及尾矿库周边地表水和地下水的样品,运用原子荧光光谱(AFS)和电感耦合等离子体质谱仪(ICP-MS)分析了多种重金属元素的含量。发现土壤、水和植物中都存在不同程度的As,Hg,Cu,Zn和Pb等元素的富集现象,而且不同元素之间的富集程度也有所差异;重金属元素含量随着远离尾矿库,有逐渐递减的趋势。The tailing pool in Yangshanchong,Shizishan copper mine of Anhui Province was constructed in 1966 and deactivated in 1991. This paper studies the geochemical distribution of heavy metals of the tailing pool and its surroundings. The samples were collected from three different locations： inside the tailing pool, farmland near the pool and farmland far away from the pool. Using AFS and ICP-MS the As, Hg, Cu, Zn, Pb etc. contents in soil,water and plants of these three locations are measured, the enrichment degrees of heavy metals are identified, and the distribution features of heavy metals are discussed. The results show that there is a difference in enrichment degrees for different elements. The further the distance to the tailing pool, the lower the heavy metal contents.
