贵州某铅锌矿区土壤重金属污染评价
|
摘要
为了解贵州某铅锌矿区土壤重金属污染状况,对矿区土壤重金属(Cu、Cd、Cr、Pb、Zn)含量进行了研究,并对其污染及来源进行了评价与分析。结果表明:土壤已受Cd、Pb和Zn污染,其中Cd污染最为严重,是国家土壤环境质量二级标准的39.5倍。综合生态风险指数平均为749.60,属于严重生态危害。Cu、Cd、Pb和Zn两两之间呈显著相关(P<0.01),因子分析提取2个主成分(F1和F2),可解释总变量的82.04%,Cu、Cd、Pb和Zn贡献约61%,它们的来源可能相同。
In order to investigate the heavy metals pollution in soil, the concentrations of Cu、Cd、Cr、Pb andZn in the soil of a Pb-Zn Mine in the Guizhou province were analyzed. The results show that the soil was seri-ously polluted by Cd、Pb and Zn, Cd pollution is most serious especially, according to Environmental QualityStandard for Soils(GB19618─1995), the concentration of Cd was more than 39.5times, The integrated ecologi-cal risk index was at the heavy- severe ecological hazard level, the average value was 749.60. Analysis of corre-lation showed that Cu, Cd, Pb, and Zn in soils may originate from the same source that Pb-Zn mine mining andprocessing for their highly significant correlation(P<0.01). Factor analysis of the extracted 2 principal compo-nents( F1 and F2) from the heavy metal element variables, and were adequate to explain 82.04% of the totalvariable, which Cu, Cd, Pb and Zn contribute about 61%.
