汞污染土壤植物修复技术研究进展

Phytoremediation of mercury contaminated soil: A review

汞是一种全球性污染物,汞污染土壤的修复问题,一直倍受各国科学工作者关注,土壤汞污染的植物修复技术是近年来发展起来的新兴技术。其中,汞污染土壤的植物提取技术是最有发展前途的一种汞污染土壤植物修复技术。本文对国内外有关汞污染土壤的植物修复技术进行了系统分析,对有关汞污染土壤的植物修复应用技术,如植物挥发、固化及提取等修复方法进行了评述,探讨了植物修复技术在汞污染土壤修复中的应用前景。加快对汞超积累植物的筛选和植物体对重金属耐性机制的研究,对今后开展汞污染土壤的植物修复工作具有重要的现实意义。

Mercury （Hg） is considered as a global pollutant, and the remediation of Hg contaminated soil always poses worldwide concern. Phytoremediation is a new technology developed recently for the remediation of Hg contaminated soil, in which, phytoextraction is a kind of most favorable phytoremediation techniques. This paper introduced the phytoremediation techniques of Hg contaminated soil at home and abroad, including phytovolatilization, phytostabilization and phytoextraction, with their application prospects discussed. It was considered that the study of Hg-hyperaccumulation plants and their tolerance mechanisms is of significance for the phytoremediation of Hg contaminated soil.
