【摘要】 通过实地调查取样,分析了辽宁省铁岭柴河铅锌尾矿库内受尾矿污染的土壤重金属含量,以及生长于其上的9种植物对Cu、Cd、Pb和Zn的吸收和富集能力。结果表明,Zn在小叶杨和刺玫蔷薇体内的含量较高;Cd在小叶杨和白莲蒿体内积累较多;而Pb在绣球绣线菊和华北蓝盆花中积累较多。但各种植物对重金属的富集能力均未达到超富集植物的要求,需采取综合农艺措施进行铅锌尾矿库污染土壤的植物修复重建工作。更多还原

【Abstract】 A survey on soils and nine plants growing on the soil polluted by Zinc-lead mine tailing wasteland in Tieling City was conducted. The concentration and heavy-metal enrichmentalabilities of Cu, Cd, Zn and Pb in the nine plants were measured. Populus simonii and Rosa davurica were proved to have certainly Zn-tolerant ability. The concentration of Cd in Populus simonii and Artemisia sacrorum were higher than that of other species. While Pb were higher in Spiraea blumei and Scabicsa tschiliensis. However, no hyperaccummulators of these four heavy metals were found in the survey. Further research on how to remediate the zinc-lead contaminated soil by integrated methods should be conducted.更多还原
