| 摘 要： | 土壤重金属污染日益受到关注,重金属是垃圾渗滤液的主要成分之一。本文对苏北某市的一废弃垃圾堆放场周围的农田土壤进行分析,通过测定重金属的全量以及有效态含量来评价垃圾场的污染程度。结果表明垃圾场周边农田土壤Cd含量超过国家土壤质量二级标准,说明垃圾场周围的土壤可能存在重金属Cd的农产品污染风险。Hg、As、Pb、Cr四种元素的含量均高于非污染土壤,但都未超过土壤质量二级标准。随着距离的增加土壤重金属含量呈现出减少趋势,垃圾堆放点对周边大约150m范围内的土壤产生重金属污染。

| Abstract: | Heavy metal contamination of soils have had increasing concern,heavy metals were major components of the leachate.The farmland soil was analyzed around a scrap dump in northern Jiangsu.The amount of heavy metals as well as the effective state-wide was used to evaluate the content of the pollution of the garbage dump.The results showed that Cd of the farmland around dumps was more than the national soil secondary standards.It may have the risk of Cd pollution of agricultural products.Hg,As,Pb and Cr content ... |
