摘要
根据东至县地质背景和母岩类型,将成土母质可划分为8个类型。对这8种成土母质土壤中的Hg、Cd、Cu、Cr、Pb、As、Ni、Zn等重金属元素进行取样测试,分析其富集程度,并对比不同母质土壤中重金属含量。结果显示,研究区8种类型母质的土壤重金属元素含量基本表现为Cr>Zn>Pb>Cu≈Ni>As>Cd>Hg的规律,但也有个别例外。湖泊沉积物、碳酸盐岩类残坡积物对重金属元素的富集作用较为显著。
According to the geological background and parent rock types of Dongzhi County,the soil forming parent material could be divided into eight types.Heavy metal elements including Hg,Cd,Cu,Cr,Pb,As,Ni,Zn in these eight parent soils were sampled and tested,their enrichment degree was analyzed,and the heavy metal contents in different parent soils were compared.The results showed that the content of heavy metal elements in the soil of the eight types of parent materials in the study area was Cr>Zn>Pb>Cu≈Ni>As>Cd>Hg,with some exceptions.The accumulation of heavy metals in lake sediments and carbonate residual slope deposits was significant.
