| 摘 要： | 对广东大宝山矿区土壤Cd、Pb、Zn、Cu含量进行了测试与分析,采用单因子污染指数法和内梅罗综合指数法对土壤重金属污染状况进行了评价。结果表明,大宝山矿区土壤中重金属含量差异较大,但都要明显高于广东省土壤重金属背景值。27个土壤样品中,Cd和Cu的单因子污染指数都大于1,超标率达100%,有21个土壤样品的Pb和Zn的单因子污染指数大于1,超标率为77.8%。从综合污染指数来看,27个土壤样品的综合污染指数在5.74～157.23之间,所有样品的综合污染指数都要大于3,表明矿区土壤已受到重金属严重污染,其中以Cd、Cu的污染最为严重。 |

| Abstract: | The Cd,Pb,Zn,Cu contents of soil at Dabaoshan mine were analyzed and the condition of soil pollution caused by heavy metal was evaluated by using single factor pollution index and N.L.Nemerow comprehensive pollution index in this paper.The results showed that there were great difference in the content of heavy metals of different soil,but they were all significantly higher than the background value of heavy metal of soil in Guangdong province.Within the 27 soil samples,single factor pollution indexes of Cd and Cu were all greater than 1,all of which exceeded the standard.There were 21 samples that the number of the single factor pollution index of Pb and Zn were greater than 1,and the exceeding standard rate was 77.8 %.The N.L.Nemerow comprehensive pollution indexes of 27 soil samples were in the range of 5.74-157.23,and were over 3.It was indicated that the soil has been severely polluted by heavy metal,especially by Cd and Cu. |
