土壤镉污染特征及污染土壤的植物修复技术机理

Characteristics of Cd pollution in soil and the mechanisms of phytoremediation for soil contamination

论述了土壤Cd污染的特点、Cd在土壤中的形态转化特征、生物毒性及我国目前土壤Cd污染现状及危害。系统论述了Cd污染土壤的植物修复治理机理、研究进展及应用前景,并结合我国土壤Cd的污染特点和部分研究结果,提出今后的研究目标和方向。

The characteristics of Cd pollution in soil, Cd forms transformation in the soil and its biological toxicity are reviewed in this paper, In addition, the current situation and harm of soil Cd contamination are discussed. Meantime, the re medial mechanisms of phytoremediation for Cd-polluted soil, the research progresses and the applying prospect are described in detail. And the aims and directions for further research are put forward.
