A Survey on Heavy-metal Content in Plants and Soils in Zinc-lead Mine Tailing Wasteland

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.
