【摘要】 在对铜陵林冲尾矿库复垦土壤中重金属 (Cu、Pb、Zn、As)含量的分析测定的基础上 ,对该复垦土壤进行了重金属环境质量现状值的检验和计算。同时采用单因子污染指数法、内梅罗综合污染指数法对其进行了评价 ,结果表明铜陵林冲尾矿库复垦土壤不同程度地受到 Cu、Zn、As的污染 ,其中 Cu与 As的污染尤其严重 ,进而指出在此尾矿库复垦土壤中种植作物的生长及食用安全可能受重金属污染的直接影响 ,从而对附近居民的身体健康构成潜在的威胁更多还原

【Abstract】 Contents of such heavy metals as Cu, Pb, Zn and As in the reclaimed soil of Linchong tailings reservoir of Tongling are analyzed,and the current environment quality values are checked up and calculated. The single factor index and Nemerow integrated index are used to assess the heavy metals pollution in the reclaimed soil. The results show that the soil is polluted with heavy metals Cu, Zn and As,and that especially, the pollution degrees of Cu and As are very serious. The heavy metals not only directly affect the growth of crops and the edible safety but also potentially influence the health of the neighbouring people.更多还原
