摘要:
在云南省呈贡县斗南蔬菜基地采集耕作层土壤样品,分析土壤中重金属(Cd、Cu、Pb、Cr、Zn)全量和赋存形态,并对潜在的生态风险进行评价,探讨研究区土壤理化性质对重金属形态的影响.结果表明,Pb含量的平均值低于背景值,而Cu和Cd平均含量超过了土壤环境质量标准.土壤中Cu可能来源于工业废物的排放,Cd、Zn、Cr元素的积累主要来源于过量肥料的施用.与其他重金属相比,Cd的可交换态含量较高,其移动性和生物毒性最强.研究区耕作层土壤Cd呈中等污染,生态风险性极强,是主要的重金属污染.耕作过程中营养盐的添加易造成耕作层土壤重金属的累积,同时会导致土壤中Cd的活动性增强,加剧Cd对作物的毒害作用.
