Phytoremediation- A Green Technology for Cleaning the Environment

Abstract

The use of “bioremediation” as a technology and tool was mainly introduced to reduce the high toxic levels of pollutants to a low level by the aid of micro-organisms. But it is less successful when
extensive metal and organic pollutants are considered. Heavy metals are poisonous for microorganisms as
they explicit direct influence on the biochemical and physiological processes. Thus, to overcome this, a new
technology of treating the pollutants was introduced, widely known as phytoremediation. Phytoremediation
is a combination of techniques used by the employment of plants to accumulate or extract the pollutant on
site within its plant parts. It is considered as the one of the best alternative to detoxify pollutants from soil
and water. This review comprehensively explains about phytoremediation and the various techniques adopt
ed to deal with the contaminant.
