| 摘 要： | 内容摘要:采用连续提取法对岩溶区铁锰结核胁迫下的土壤重金属元素的形态进行了分析，并用原子吸收分光光度法对重金属元素的含量进行了测定。结果表明，土壤A、B层Cd、Cr、Cu、Pb、Zn以残渣态所占比例最高，Mn以铁锰氧化态所占比例最高；土壤A、B层生物可利用态所占比例以Cd最高，其它元素所占比例甚低，Cd成为本区的主要污染因素，Mn元素的潜在可利用态所占比例最高，也应加以注意其影响。

| Abstract: | The speciation of heavy metals in Fe-Mn nodules soil in Litang karst area was analyzed by using Tessier A sequential extraction method, and the heavy metal contents were detected with atomic absorption spectrophotometry (AAS). The results showed that in A and B layer soil, the highest proportion was found in Cd, Cr, Cu, Pb and Zn of residual form and Mn of Fe and Mn-oxides bound forms; Cd in bioavilable form possessed the highest proportion in A and B layer soil, while others had very low. Cd was the main p... |
