土壤重金属元素生物有效性分析方法的研究进展

Research Progresses in Aanlytical Method on Bioavailability of Heavy Metals in Soil

土壤中重金属元素的生物有效性是评价土壤重金属污染程度的一个重要指标,尽管各个国家和地区都制定了相关标准,但是在世界范围内还未制定评估土壤各金属元素生物有效性的统一标准。介绍了近几年来国际上通用的土壤重金属元素生物有效性分析方法,并指出各种方法适用的土壤特性,及需要解决的问题与今后的发展方向。

The criterion to assess whether metals present in soils are at toxic levels is not standardised world-wide and varies from one country and land use to another.A review with 48 references is given on the current methods for bioavailability evaluation of heavy metals in soil,including its application regions and disadvantages.The concerned problems and future development orientation are also pointed out.
