土壤重金属污染的植物修复技术综述

Review on Phytoremediation Technology of Soil Contaminated by Heavy Metal

随着人类社会城市化和工业化不断发展,重金属在土壤中不断积累,对环境和人类健康产生极大危害.土壤重金属污染的植物修复技术作为一种环境友好型治理措施,以其低成本、治理过程的原位性等特点越来越受到国内外研究者关注.在参考国内外的相关文献基础上,主要从土壤重金属污染的来源以及危害出发,对超积累植物研究现状,该项技术中超积累植物的修复机理,以及修复植物的产后处置进行了综述,并对该研究领域存在的问题和今后的研究与应用进行了简要的讨论.参33.

With the consistent development of urbanization and industrialization of human society,the accumulation of heavy metals in the soil has been a serious threat to the environment and human beings. Phytoremediation to the heavy metal contaminated soil is considered as an environmental-friendly treatment which gets more and more attention from domestic and overseas for its low cost,in situ and other advantages. Referring to a mountain of domestic and foreign literatures,this paper presents the research progress of the hyperaccumulators,the theory of hyperaccumulator phytoremediation and the disposal of hyperaccumulator phytoremediation,from the standpoints of the source and harm of heavy metal contamination.The problems, the researches and the applications in the future are also briefly discussed in this paper.33refs.
