| 摘 要： | 利用河北省多目标地球化学调查资料,研究了廊坊地区表层土壤中重金属元素As、Cd、Cr、Hg、Pb的富集特征与污染程度.与我国土壤元素背景值相比,廊坊地区表层土壤中Hg的富集系数较大；与研究区元素背景值相比,Cd、Hg富集系数较大,富集程度依次为Hg＞ Cd＞ Pb＞ Cr＞ As.地积累指数污染评价结果表明,以全国土壤...

| Abstract: | Using the multi-objective geochemical survey data obtained from Langfang,the authors studied enrichment characteristics and pollution degrees of As,Cd,Pb,Cr and Hg,which are five kinds of heavy metal elements in surface soil.Also,the five kinds of heavy metals were comparatively investigated with the quality evaluation method.The single factor index method indicates that Cd causes rather heavy pollution.Geoaccumulation index of pollution evaluation shows that,viewed from the background value of soil heavy m... |
