| 摘 要： | 选取重庆市表层土壤样品,采用Tessier A连续提取法研究了土壤中Hg、Cd、Cr、Cu、Zn、Ni等6种重金属元素进行形态分析。结果表明,在该区域表层土壤中Cd以离子交换态为主,其余的重金属元素均以残渣态为主,说明Cd较活泼,对环境有潜在的影响力,Hg、Cu、Zn、Ni、Cr相对比较稳定。

| Abstract: | The speciation of heavy metals in soil samples from Chongqing city was investigated using Tessier A sequential extraction method.The results show that Cd is mainly in exchangeable,others are mainly in residual fraction.Concludes that Cd is more active,and it has potential impact on environment,so more attention should be paid to it,others are relatively inert. |
