摘要
在前人研究的基础上,通过韩国Okchon地区黑色页岩土壤及相应成土母岩的对比,得知黑色页岩土壤的重金属元素特征具有母岩继承性.并与发育于其他基岩(花岗岩、玄武岩、石灰岩)上的土壤进行对比分析,概括了黑色页岩土壤的重金属和稀土元素地球化学特征.应用富集系数法(EI)对韩国、贵州、湖南3个地区的黑色页岩土壤进行重金属污染评价,发现大部分黑色页岩土壤均受到不同程度的重金属复合污染.
In this paper, on the basis of previous studies , by South Korea Okchon regions black shale soil and parent rock contrast , learned that the heavy metals element characteristics of the black shale soil is parent rock inheritablel.And the soils development in other rocks (granite, basalt, limestone) were analyzed, summed up the black shale soil heavy metals and rare earth elements geochemical characteristics .Enrichment factor ( EI ) is the application of South Korea , Guizhou , Hunan three areas of the black shale soil heavy metal pollution evaluation , found that most of the black shale soil have been varying degrees of heavy metals compound pollution .
