中文摘要:
      通过野外采样和实验室分析，研究关中西部某铅锌冶炼区周边耕地土壤中重金属元素的含量，并进行了污染评价。结果表明，该铅锌冶炼区周边耕地土壤中Pb、Zn、Cu、Cd、Cr、Hg、As、Ni的平均含量分别为47.95、128.53、26.13、1.09、91.5、0.164、12.2 mg·kg-1和27.1 mg·kg-1，除了Ni元素，均高于陕西省土壤元素背景值。评价结果表明，该铅锌冶炼区周边耕地土壤已经达到了中重度污染程度，其中重金属Pb、Hg和Zn污染较严重，耕地土壤重金属复合污染较严重。
英文摘要:
      Through the methods of field sampling and experimental analysis, the contents of heavy metals in farmland soil around a lead-zinc smelting plant in western Guanzhong Plain were investigated and the pollution assessment was conducted. The results showed that the contents of Pb, Zn, Cu, Cd, Cr, Hg, As and Ni were 47.95, 128.53, 26.13, 1.09, 91.5, 0.164, 12.2 mg·kg-1and 27.1 mg·kg-1, respectively. Except for Ni, the contents of all other elements were higher than the soil background values in Shaanxi Province. The assessment results showed that the pollution of heavy metals in the farmland soil around the lead-zinc smelting plant was moderate or serious, in which the pollution of Pb, Hg and Zn was serious, and the comprehensive pollution in the farmland soil was serious.
