Heavy metals are persistent environmental pollutants that are introduced into the environment by natural processes and anthropogenic activities. Environmental pollution caused by heavy metals has become a severe threat to environment and life causing serious health effects. Removal of heavy metals from the environment is a real challenge and over the years, various physiochemical methods were used for its removal. Recently, bioremediation approach involving microorganisms have gain interest and the new approach is widely used for treating heavy metals from contaminated environment. Bioremediation approach has many advantages over other conventional methods as it is environmental friendly, safe and easy to handle. Microorganisms have significant role of heavy metal detoxification, however, due to dearth of knowledge on the molecular mechanism involved in metal detoxification their application in the field of bioremediation has been limited. This review describes how bioremediation approach involving microorganisms as agents for elimination of toxic metals from contaminated sites. The present review also focuses on potential adverse effects on human health issues from long term exposure of heavy metals.
