Study on Soil Heavy Metal Pollution and Phytoremediation

This paper generalized the current situation of soil heavy metal pollution and its increasing harm to the environment in China,and also summarized the contaminated phytoremediation types and their advantages and disadvantages.In terms of the research progress of hyperaccumulators,this paper proposed germplasm resources of hyperaccumulators in some common soil contamination(copper,nickel,lead,zinc,cadmium) and expounded the tolerance and concentration mechanism of the plants to heavy metal.Lastly,this paper indicated the future research direction and development trend of the phytoremediation technology by means of the discussion on the limitations of phytoremediation technology.
