Bioremediation of Heavy Metals: A Substantive Potential for Clean Earth

Abstract

Modern industrial and agriculture developments, anthropogenic activities effected terrestrial and aquatic pollution of heavy metals posing serious threats to biotic (human/animal/plant) and environmental health, as well as, welfare of any nation. Phytoremediation of metal polluted sites has attracted worldwide significance due to its being less expensive and environment-friendly properties. Robust information is available on heavy metal remediation, phytoremediation and several plants are recorded worldwide which hyper accrue wide category of heavy metals. This communication emphasizes various remediation methods, especially phytoremediation for heavy metals along with its advantage compared to other techniques. Phytoremediation technique is specifically applicable for reclamation of sites with low to moderate pollution level due to its being energy efficient and aesthetically pleasant, also it can be co-practised with various conventional remedial processes as an ultimate procedure for remediation process.
