A Review on Green Technology, Heavy Metal Phytoremediation

Abstract

Organic or inorganic contaminants have polluted the environment. Organic pollutants are mostly manmade and enter the environment in a variety of ways. As a consequence of global industrialization, soil pollution with hazardous metals including such Cd, Zn, Pb, Cr,  Ni, or  Cu has risen significantly in recent years. There are several traditional remediation methods that may be used to remediate polluted regions, particularly metal-contaminated soils. Despite their efficiency, these techniques are costly, time-consuming, and harmful to the environment. Scientists and engineers have recently created phytoremediation as a cost-effective and ecologically friendly technique in which biomass/microorganisms or live plants are utilized to repair contaminated regions. Phyto filtration, Phyto stabilization, phytoextraction, as well as phytodegradation are only a few of the uses available. To demonstrate the broad application of this green technique, a short overview of phytoremediation of heavy metal-contaminated soils has been compiled.
