摘要
指出了利用超富集植物去除土壤中的重金属已经引起国内外的广泛关注。回顾了国内外土壤重金属污染的事件,从4个方面论述了土壤重金属的污染来源,从重金属离子的迁移转运、超富集重金属植物的选择和植物的预警作用等方面探讨了超富集植物修复和应用,并对该领域中存在的问题进行了讨论。
Removing heavy metals in soil by using hyperaecumulator has drawn extensive attention from all over the world. This paper briefly reviews the famous events of metal pollution in soil at home and abroad, discusses the soureeof heavy metals pollution in soil from four aspects,and elaborates the phytoremediation and application from aspects of the migration,transport of heavy metals ion, selection of hyperaccumulator and telltale effects of the plants. Finally,it discusses the key problems existing in this field.
