摘要: 对上海崇明岛地区表层土壤中重金属元素的分布特征进行了研究,结果表明崇明岛表层土壤未受人为污染。运用标准化方法计算了崇明岛地区表层土壤中重金属元素镉、铬、铜、铅、锌、砷的环境地球化学基线值,建立了元素镉、铬、铜、铅、锌、砷的环境地球化学基线模型,确定其环境地球化学基线值分别为0.19、71.97、31.32、24.79、86.43、8.34 μg/g。与上海市土壤背景值进行了对比检验,结果显示,标准化方法能有效计算土壤中元素的环境地球化学基线,获得的基线符合其定义和实际意义,为区域经济发展规划和环境评价提供了实用的基础地球化学信息。Abstract: The distribution characteristics of heavy metals in surface soils of Chongming Island were studied. The results showed that the surface soils in Chongming did not suffer from anthropogenic pollution. The environmental geochemical baseline values for heavy metal elements of Cd, Cr, Cu, Pb, Zn and As in the surface soils of the Chongming Island were calculated using normalization procedure and the environmental geochemical baseline values for these heavy metal elements are 0.19, 71.97, 31.32, 24.79, 86.43, 8.34 μg/g respectively, which consistent with Shanghai soil background values. The results also showed that normalization procedure can effectively calculate the soil environmental geochemical baseline values of heavy metal elements and can provide basic geochemical information for the regional economic planning and the environment evaluation.
