ABSTRACT
The problem of heavy metals (HMs) contamination is a wide scale concerned in light of their harmfulness for plant, animals, and human due to their toxicity potential. They have higher capacity to bioaccumulation and cause harm to natural system such as man, wild animals, small organisms, and plants. It is a significant concern for natural ecosystem wellbeing and security. HMs can reaches the human tissues through non-identical pathways, for example, direct eating of food stuff, skin contact, diet through the soil evolved way of life, inward breath and oral admission may truly influence their wellbeing. A few of the customary techniques are either very expensive or they are not efficient to remediate polluted sites. Moreover, biotechnological approaches for bioremediation, i.e. includes biomineralization, bio-sorption, bio-stimulation, are good to deal with the contaminated sites. This chapter features better comprehension of the issues related with the harmfulness of HMs to the polluted environments and their reasonable, feasible, and eco-accommodating bioremediation advances alongside some contextual analyses in India and abroad.
