摘要
重金属形态决定了其在土壤中的迁移能力和有效性。综述了土壤中重金属Cd不同形态的分类及提取方法,不同Cd形态比重及其对植物的有效性问题,以及Cd形态的生物有效性的影响因素,并列举了Cd形态分析的最新研究方法,指出了进一步研究的方向。
The mobility and the availability of heavy metals in different types of soil depend on their specific chemical forms.This article reviewed the classification and extraction methods for different forms of heavy metal Cd in soil,the proportions of different Cd forms in soil and bioavailability of it to plants,and the influencing factors for bioavailability of different forms of Cd.Moreover,the latest research methods for analyzing Cd forms were introduced,and the further study direction was also pointed out.
