Abstract:

利用野外采样与实验室分析相结合的方法,以湘中某冶炼区稻田土壤(0—20cm)为研究对象,分析其中的Cd、Zn及Pb含量,评价其重金属污染程度与潜在生态风险.单因子污染评价结果表明,100%的土壤样点Cd处于重度污染;有96.0%的样点Zn处于重度污染,有99.5%的样点Pb处于重度污染,土壤的重金属污染程度为Cd>Pb>Zn.潜在生态风险评估结果显示,大多数样点Zn处于轻度生态风险;Pb每个生态风险级别的样点都有,其中处于强生态风险样点居多;100%的样点Cd处于极强生态风险水平.综合潜在生态风险表明,11.0%样点综合潜在生态风险达到很强水平,89.0%样点综合潜在生态风险处于极强水平.上述各项指标综合表明,湘中某冶炼区农田土壤受到了严重的重金属污染.
