超富集植物治理重金属污染土壤研究进展

Phytoremediation of Heavy Metal Con taminated Soil by Hyper-Accumulators:A Review of Researches in China and Abroad

就国内外植物修复技术领域的研究进展作了综述,阐述了迄今报道的超富集植物、超富集植物吸收重金属生理机制、研究动态与前景。

Phytoremediation is a promising te chnique for treatment of heavy metal contaminated soil.Hyper -accumula tor and phytoremediation are research hots pots in many fields such as environme ntal science,plant science,soil sc ience and ecology science now.There are reports about utiliza tion of hyper -accumulators capable of accumulating heavy metals such as Co,Cu,Ni,Pb,Mn,Zn,Cd,Cr,Se.This paper reviews the studies on this field in China and abr oad,with special focuses on hyper -a ccumulators,their mechanism of hyperaccumulating heavy metals and the possible applications.
