Research Progress of Cadmium Transformation and Accumulation in Soil-plant System

WU Da-fu et al(Henan Institute of Science and Technology,Xinxiang,Henan 453003)  
Cadmium not only caused environmental pollution,but also was harm to plant,animal and human.Food chain was the major path of cadmium causing danger or potential danger to human.Cadmium in contaminated soil accumulated in edible parts of plant through in vivo movement and nutrient uptake by plant roots.The major factors affected transformation and accumulation were the character of soil,plant kinds or varieties and so on.The aim of this paper was to discuss the pathway of reducing cadmium contamination.
