| 摘 要： | 通过对某铜矿区土壤重金属含量及化学形态分布进行分析,探讨了采矿过程中的重金属在土壤中的积累特征。结果表明,该矿区的Cu、Zn、Pb、Cd、Ni在土壤中的积累程度相当高。各采样点的重金属综合污染递减顺序依次为:堆浸泥>最后沉淀池>堆浸矿>堆浸土>金矿排污口污泥>原生土壤>铜矿区下游江边土壤。堆浸矿土壤的重金属以残渣态、水溶态、有机质硫化态这三种组分为主,而堆浸泥土壤则以Fe-Mn氧化物结合态为主。

| Abstract: | Through analysis of heavy metals content and speciation in the soil of a copper ore area,accumulated characteristics of heavy metals in soil in the process of mining were discussed. Results indicated that copper,zinc,lead, cadmium and nickel have highly accumulated in the soil,with the descending order of the composite pollution degree of heavy metals in each sampling site as stack mud,final deposition,stack mine,stack soil,gold mine trough,natural soil and downriver of mining area. Heavy metals of stack mine were mainly in residual,aqueous and organic fraction,but heavy metals of stack mud were mainly in Fe-Mn oxides fraction. |
