PHYTOREMEDIATION TECHNOLOGY IN THE METAL MINE WASTE PLACE POLLUTED BY HEAVY METAL

The environmental problem brought about by the exploration of metal mine is becoming more and more severe,The exploration of mine destroy balance of ecology.The heavy metal pollution in the metal mine waste place is very severe.Phytoremediation is widely used in the treatment of soil heavy metal pollution in all the world..But phytoremediation still have some problem to solve.The lead and zinc mine is investigated in this text.The text summarize something as follow: The harm to soil and plant bring about by lead,the progress in the research about filtration of hyper accumulators to lead、the influential of factor hyper accumulators concentrated lead and the mechanism how the hyper accumulators absorb and accumulate lead,also the problem can not be solved at present and development tendency in the future.
