Abstract
Estuaries in the areas prone to anthropogenic activities are exposed to multifarious pollutants. Toxic
concentrations of heavy metals do exist with persistent organic compounds in such estuaries prolonging
the recalcitrance and ecotoxicological consequences of the chemicals, which impact on the health of the
brackish water and by extension, the oceans. The quest for high aesthetic quality of the estuarine
environment is gaining attention from global campaign, which requires effective remedial strategies to
replace the physical and chemical methods in use that are costly and often leave behind toxic residues in
the environment. Contrary to physico-chemical remedial processes, bioremediation strategies are projected as a promising green technology to remove pollutants from the estuarine environment. The
concept of bioremediation involves the use of competent biological elements such as microorganisms
and plants, along with or without the biomolecules they produced, to ameliorate pollution. Therefore,
this paper reviews the various bioremediation technologies that would be applicable to decommissioning estuarine environments polluted with toxic metals and persistent organic compounds.
