摘　　要：对南京市某垃圾填埋场的垃圾、土壤、植物、炉渣等样品中Cu、Pb、Cr、Zn、Cd、Hg、As、Sb、Mn重金属含量进行分析。结果表明,垃圾填埋场的填埋土中Cu、Zn、As 3种重金属含量分别高出自然土壤背景值86%、250%,300%。潜在生态危害指数法评价的污染状况为:Cd、As>Hg>Cu>Pb>Cr、Zn;Cd和As的毒性贡献较大,存在极高的潜在生态风险。The Cu, Pb, Cr, Zn, Cd, Hg, As and Sb Mn were analyzed in the samples of garbage, soil, vegetables and slag of a municipal landfill in Nanjing. The results showed the levels of Cu, Zn and As were 86% , 250% and 300% of background values separately. The pollution levels of were Cd, As 〉 Hg 〉 Cu 〉 Pb 〉 Cr, Zn by potential risk assessment. The Cd and As had great contribution to the toxicity and heavy potential ecological risk.
