Abstract

The persistence of heavy metals in the environment may pollute or contaminate soils and aqueous streams as both natural components or as the result of human activity. Bioremediation process in this regards is an option that offers the possibility to destroy or render harmless various contaminants using plants and microbes. Amongst the various bioremediation processes, phytoremediation and bioremediation by microbes are quite effective. Phytoremediation includes the removal of contaminants with the help of green plants, while the microbial bioremediation includes the removal of heavy metals by microorganisms (bacteria, fungi, yeast and algae) as sorbets. Amongst the various heavy metal contaminants arsenic and lead are recognized as the leading toxicants worldwide and having the various toxic effects on human and animal health as well as on the environment. The aim of this article is to give an overview of the arsenic and lead contaminant in soil and also the mechanism of removal of these toxic metals from the contaminated sources by the potent application of plants and microbes.
