摘要：

为了评价遵义东南部地区农业土壤的重金属污染状况，以Sc为标准化元素，应用标准化方法建立了遵义东南部地区农业土壤重金属Cd、Pb、Cr、Hg、As的环境地球化学基线模型，在此基础上运用富集因子法评价土壤的重金属污染状况。结果表明，该区域农业土壤中40%受到Cd的污染，53%受到Pb的污染，60%受到Cr的污染，40%受到Hg的污染，40%受到As的污染，污染级别均为1级，表明土壤受到了轻微扰动。

Abstract:

In order to evaluate heavy metals pollutions in the agricultural soil in southeast area of Zunyi, by using Sc as standardized factor, environment baselines models of heavy metals including Cd, Pb, Cr, Hg, As were obtained. At the same time, heavy metals pollutions in the agricultural soil in southeast area of Zunyi were evaluated by enrichment factor method. The results showed that 40% of soils were moderate polluted by Cd, Hg, As, 53% of soils were moderate polluted by Pb, 60% soils were moderate polluted by Cr. The rank of pollution was 1 level, and soils had been slight polluted by heavy metal pollutions in this area.
