To distinguish geogenic enrichment from anthropogenic pollution of heavy metals(Cd,Cu,Cr,Co,Ni,Zn,Hg,Pb,Mo,and As)in agricultural soils,32 sampling locations were selected in the coastal plain of eastern Zhejiang province.
Cd、Cu、Zn、Hg和Pb为主要污染元素,其耕作层含量明显高于心土层,可提取形态的比例较高;其中,Cd、Cu、Zn和Pb有相似的人为污染来源,而Hg有不同的人为污染来源。
3) artificial contaminant

4) man-made pollution sources
人为污染源
5) synthetic contaminated soil
人为污染土壤
1.
