Abstract通过实地采样调查和对样品进行实验室分析,研究了湖南锡矿山锑矿区采矿区、冶炼区和尾矿区附近农用土壤的锑、砷及汞的污染状况。结果表明这3个区域8个采样点的农用土壤均受到这3种重金属元素较高浓度的污染,土壤中锑、砷及汞的浓度分别为:141.92~8733.26、14.95~363.19和0.16~5.68 mg/kg,均远高于湖南土壤中这3种元素的背景值。锑与砷的平均浓度是荷兰土壤中锑、砷最大允许含量的695和2.3倍,而锑矿区农用土壤中汞的平均含量与荷兰土壤中汞最大允许含量2.2 mg/kg接近。在3个研究区域中,冶炼区的土壤中这3种元素的浓度均为最高,采矿区和尾矿区的依次减少。通过用地累积指数法评估锑矿区农用土壤中上述3种重金属污染程度发现,锑矿的开采和冶炼是矿区农用土壤受到重金属严重污染的根本原因,其中锑对土壤重金属污染的贡献最大。
