Abstract:

Phytoremediation employs the use of plants, alone or together with their associated microorganisms, to degrade, contain or stabilize various environmental contaminants in soil, water, and air. The advantages of phytoremediation are:1) It is an aesthetically pleasing, solar-energy driven cleanup technology;2) There is minimal environmental disruption and in situ treatment preserves topsoil; 3) It is useful for treating a broad range of environmental contaminants; and 4) it is inexpensive(60%～80% or even less costly ) than conventional physico-chemical methods. Phytoremediation is wildly viewed as the ecologically responsible alternative to the environmentally destructive physical remediation methods currently practiced. With the development of genic engineering technology, transgenic plants play a major role in this field. This paper introduced the significant progress of the phytoremediation of soil with heavy metals and organic pollutants by transgenic plants.

Key words: soil, heavy metals, organic pollutants, transgenic plants, phytoremediation
