某城市垃圾填埋场周围土壤重金属污染状况分析

摘要

In this paper,the heavy metal content and the ecological risk in the farmland soil around a city landfill site was studied. The results showed that the content of heavy metals in the soil around the urban landfill decreased gradually with the increase of the distance from the municipal solid waste landfill site. Using Nemerow index and Potential ecological risk hazard evaluation method demonstrated soil has different levels of heavy metal of urban garbage landfill field the pollution.%本文对某城市垃圾填埋场周围的农田土壤中重金属含量进行研究和生态危害进行分析。结果表明从城市垃圾填埋场周围土壤重金属含量特征上看，重金属含量随着城市垃圾填埋场距离的增加逐渐降低。利用内梅罗指数法及潜在生态风险危害法对城市垃圾填埋场周围土壤重金属生态风险进行评价，发现该地土壤存在不同程度的重金属污染。
