摘要
Samples were collected from agricultural soils in Jiashan, Zhejiang Province. By measuring the concentrations of heavy metals and revealing the chemical speciation distribution, it is concluded that the concentrations of Cd, Cu, Hg, Ni and Zn in Jiashan are higher than those in Jiaxing and the north of Zhejiang Province. Meanwhile the concentrations of As are between Jiaxing and North Zhejiang Province; the concentrations of Cr in Jiashan are highest, and the concentrations of Pb in these areas are almost the same. Also the values differ in different types of soils. Integrated pollution evaluation shows that the surface soil in Jiashan was dominantly slightly polluted. Attention should be paid to As and Cd, especially Ni, for they had some potential ecological risks. Though Hg is of high concentration, it is has a poor ecological risk because of its residual state.
