摘　　要：近年来,生物材料以其经济、有效和无二次污染等特点,在重金属废水处理和土壤修复方面显示出了众多的优势,可替代传统的镉污染处理方法。综述了目前国内外生物材料在处理镉污染方面的研究进展,并对今后应用生物材料治理镉污染提出了一些建议。Biomaterials are attractive for treatment of Cd contaminated wastewater and soil because they are low cost and non-polluting. The paper presents many plants and microorganisms as useful biomaterials for such purposes. More research are necessary to provide essential information on： 1） bioengineering to produce fast growing plants that accumulate Cd quickly,2） solid phase Cd species for more effective phytoremediation,3） integrated treatment in conjunction with soil flushing, land farming and agriculture,4） effects of microbial activities on Cd transport in the contaminated media, and 5） bacteria that are resistant to Cd.
