| Abstract: | Soil pollution by heavy metals has been considered as one of the main environmental problems through the world now and phytoremediation of polluted soil, especially heavy metals hyperaccumulators, is one of the important technology for the removal of metals from the environment. The concepts and the function of heavy metals hyperaccumulators were introduced in this paper. The recent researches on the characteristics of bioaccumulation, the resource of germ plasm, the species and regional distribution of hyperaccumulators, the biological mechanism of heavy metals - accumulation in plants were summarized. And the author pointed out the existing problems, also discussed the major topics in practice and significance of further research. |
