Heavy metals in plants : phytoremediation : Plants used to remediate heavy metal pollution

Abstract

In current time the environment is heavily polluted by various toxic metals, which create a danger for all living beings. These metals are retarding farming efficiency and destructing the health of the plants and animals. Now a day "green technology" minimized this problem to some extent. In this technology to clean up the contamination, such plants grow which can tolerant metal. The application of genetic manipulation and the use of naturally occurring metal tolerant plants should accelerate the process of transmitting this technology from experimental place to field. Thus careful investigation of the mechanism of tolerance of heavy metal at physiological and genetic level is essential
