| 摘 要： | 改良剂原位修复重金属污染土壤因其成本低廉、易于实施,已经得到广泛应用。然而,改良剂对土壤重金属的修复仍然存在着一定的局限性和潜在风险。无机和有机改良剂的修复效果不仅与重金属离子的种类有关,而且还受作物、土壤类型及环境因子的制约。本文就目前常用改良剂的修复效果,存在的问题,改良剂原位修复重金属污染土壤的作用机制以及国内外研究进展作简要综述,并对此方面研究的未来趋势提出展望。

| Abstract: | The method of in-situ immobilization on soil heavy metals contamination has been widely used because of its convenience and low price.However,there are some potential risks and limits on soil amendments.The immobilization efficiency of organic and inorgannic amengdments were affected by the kind of heavy metals,soil type and environmental factors.The immobilization efficiency,problems,immobilization mechanism and current situation of research on soil amendments were summarized in this paper.Some further study was stressed. |
