影响土壤中镉的植物有效性的因素及镉污染土壤的植物修复

阐述了镉的来源及其对人类的危害,并对影响土壤中镉的植物有效性的土壤因素中的pH、氧化还原电位(Eh)、有机物质、营养物质浓度对镉的植物有效性的作用作了详细的阐述。此外对其它如EDTA、淤泥等对土壤中镉的植物有效性的影响和镉污染土壤的植物修复等方面也进行了综述,并对镉污染土壤的修复治理与趋势进行了展望。

Effects of factors on Cd bioavailability in soil and the phytoremediation of the Cd-contaminated soil

The source of cadmium,its harmfulness to human health,and how soil factors(such as pH,redox potential(Eh),organic matter,nutrition concentration)and other factors(such as EDTA,sludge) affect Cd bioavailability in contaminated soils were discussed,and the trend of the study on Phytoremediation of the Cd-contaminated soil were also reviewed in this paper.
