摘要
在黑岱沟露天煤矿区设11各点位,采集土壤样品,分析测定Cr、Cu、Zn和Pb的含量水平。结果表明,Pb、Cr和Zn含量较低,但Cu的含量高于的参考值。运用潜在生态风险指数法(RI)进行环境质量评价,结果显示Cr、Pb、Cd和Zn没有显着污染,而Cu的风险指数较大,显示一定程度污染。
Soil samples were collected in eleven sites in Heidaigou open -pit coal mine to analyze Cr,Cu, Zn and Pb concentrations. The result showed that Pb, Cd and Zn contents were lower but Cu concentrations were higher than all of the reference values. Environment quality evaluation was conducted by method potential ecological risk index(RI). It revealed thatCr, Pb, Cd and Zn indicated no significant contamination, Cu exhibited contamination to some extent on the contrary.
