本文综述了镉的危害,归纳了影响镉在土壤中的生物毒性的主要因素, 如土壤性质、复合污染及植物种类等
关键词:镉,生物毒性机制,土壤镉污染Abstract:In recent years,cadmium pollution of soil is increasingly serious with the growing of three industrial wastes and sewage sludge agricultural use
However,excessive cadmium pollution of soil can poison the crops,especially residual in the edible parts
And humans may be endangered by the poisoned crops through food chain
The review has summarized the harm of cadmium and conclude the main factors of the biotoxicity of the cadmium in soil,e
soil property,soil combined pollution of other heavy metal and floristics
