| 摘 要： | 通过对某钢铁企业周边土壤重金属(Cu、Pb、Cd、Ni、Hg、As)含量的调查与分析,采用重金属单项污染指数、超标倍数、污染分担率和内梅罗污染指数评价方法对土壤重金属污染状况进行评价。结果表明,该钢铁企业周边土壤主要污染物为镉,含量在1.06~2.41 mg/kg之间,超标0.8~3.0倍。通过对除尘灰中相应重金属含量分析,弄清了土壤中重金属来源。

| Abstract: | Based on investigating and analyzing the contents of heavy metals such as Cu,Pb,Cd,Ni,Hg and As in soil around a steel enterprise,in this paper the pollution of soil heavy metals were evaluated using single pollution index,times ultra standard,the contribution ratio of pollution sources and Nemerow pollution index.The results showed that the dominant pollutant in the soil around the steel enterprise was Cd,of which the content was 1.06~2.41mg/kg with times ultra standard of 0.8~3.0.The sources of heavy meta... |
