Review on Bioremediation of Metal Contaminated Soils

Yamini Agrawal, Isha Gunwal and Payal Mago

Rapidly increasing population and industrialization are the major factors in environmental degradation. Development of eco-friendly approach to reduce environmental contamination is an issue in great demand. The challenge is to build up a cost-effective and safer technology for cleaning up of contaminated environments. Bioremediation is promising new technology to decontaminate polluted surroundings. Heavy metals are the major toxic non-biodegradable environmental pollutant and their cleanup from environment is a chief concern. Several conventional physical and chemical technologies have already been employed for their removal but majority of them are not very flourishing in terms of their cost and efficacy. Therefore, we present a review on status of studies employing biological materials (microbes and plants) for heavy metal removal and recovery.
