| 摘 要： | 通过对包钢尾矿坝5个样点的土壤进行调查取样,根据国家土壤环境质量标准(GB15618-1995),并采用单项污染指数法、综合污染指数法对该区的土壤重金属(Cu、Zn、Cd、Pb、As)含量进行评价。结果表明,依据土壤污染二级标准,尾矿坝土壤中的铜、铅、镉、锌、砷大部分在污染水平之下,都未发生污染。一级标准评价结果为铜、铅、砷都属无污染,锌为轻度污染(P锌>1),镉为中度污染(2西面>中心>东面>北面。

| Abstract: | After the soil samples in 5 sites in tailings dam of Baotou steel were investigated,the content of heavy metal(Cu,Zn,Cd,Pb,As)in Baotou steel were estimated by single factor pollution index method and the composite pollution index method according to the state environmental quality standards for soils(GB 15618-1995).The results showed that the contents of Cu,Pb,Cd, Zn and As in the soil in tailing dam of Baotou steel were under pollution level mostly and not polluted according to Ⅱ-class criteria for heavy metals in soil.The first grade standard evaluation results showed that Cu,Pb and Zn were pollution-free,Zn is the slight-degree pollution(PZn>1),Cd was middle-degree pollution(2 west> center> east> north. |
