摘要
用富集因子法分析土壤风沙尘17个元素的富集(污染)状况.结果表明,C a、C r、Co、N i、Cu、Zn、B r、Pb是广泛富集的元素;地区间元素污染级别差异显著;相对于不同参比元素(A l、F e、T i)的富集因子明显不同.
Using enrichment factor (Ef) to analyze the elements in soil dust to demonstrate the enrichment of seventeen elements. The conclusions drawn are as follows. Ca,Cr,Co, Ni, Cu,Zn, Br, Pb elements are enriched abroad. The polluted classification of elements between regions is obviously different. The enrichment factors between different reference elements (Al,Fe,Ti) are distinct.
