Abstract

  Heavy metal pollution is a serious environmental problem. There are many remediation methods to clean the soil which includes physical methods, chemical methods and biological methods. Physical and chemical methods have many disadvantages and harmful effects but biological methods are now a day’s very useful and have many advantages. One of the biological methods is Phytoremediation. It is one of the best methods to clean up the metal contaminants. It inhibits the contaminants of soil and heavy metals which are harmful for plants and for humans. If we are engulfing the food which contains heavy metals cause many harmful diseases which would be fatal and harmful. It is a green technology with good public perception. There are many molecular studies which will improve the efficacy of Phytoremediation. This review presents the status of Phytoremediation technologies with particular emphasis on Phytoextraction, Phytodegradation and Rhizofilteration of soil heavy metal contamination. Unlike organic compounds, metals cannot be degraded, and cleanup usually requires their removal. Most of the conventional remedial technologies are expensive and inhibit the soil fertility; this subsequently causes negative impacts on the ecosystem. So Phytoremediation is one of the cost effective and environmental friendly procedures.
