| 摘 要： | 通过对西安污灌土和西红柿Cu，Pb，Cd，Cr，As，Hg元素分布的研究，结果表明这些元素在污灌土中发生了明显累积，但不同元素的累积强度不同。重金属从土壤向西红柿的迁移转化中，迁移累积率在灌土中Cd＞As＞Cu＞Cr＞Hg＞Pb，而正常土中Cd＞As＞Hg＞Cu＞Cr＞Pb。西红柿不同生长阶段对土壤中重金属吸收程度不同，西红柿Cu、Cd、Hg含量与土壤中该元素含量呈明显的正相关关系。

| Abstract: | The studies on Cu, Pb, Cd, As, Hg elements content of sewage irrigated soil, general soil and tomato in Xi'an area indicates that these elements are distinctly cumulated in the sewage irrigated soil and their cumulated intensity is different from each other. The cumulated rate value in tomato in the sewage irrigated soil is Cd > As > Cu > Cr > Hg > Pb and is Cd > As > Hg > Cu > Cr > Pb in general soil. Tomato differently adsorbs heavy metal elements from soil in different growth stage. Cu, Cd and Hg contents of tomato have positive correlativity with that of soil. |
