| 摘 要： | 通过对比冀东平原表层和深层土壤样品中8种重金属含量,并利用因子分析提取了7个主因子,结合因子得分图进行重金属来源分析。结果显示Cr的来源具有分异性,一部分源于土壤本底,另一部分来源于矿业污染造成的元素叠加;Hg的来源主要为农业生产,部分地区Hg是由冶金、交通等污染排放所致;唐海县附近Cd主要为河流上游元素搬运成因。局部地区Pb高度富集是由于采矿污染造成。As、Cu、Zn、Ni等元素主要来源于当地自然地质背景。

| Abstract: | This paper has conducted a comparative study of the content of eight heavy metals in surface layer and deep layer soils.The sources of heavy metals were analyzed by factor analysis.Seven main factors were selected,and diagrams of factor scores were drawn.The results show that Cr comes from two sources:one is soil parent material and the other is mining pollution.Agricultural pollution is the main source of Hg in eastern Hebei plain,while in some areas,Hg is mostly derived from metallurgy and traffic.Cd is d... |
