ABSTRACT
Recently, heavy metals are one of the toxic environmental pollutants, as an impact of the development of industries. The presence of heavy metals in wastewater creates a destructive impact to the planet, including the demise of aquatic life, and accumulation in the human body and animals, thereby causing bone disorders, organ damage and cancer. In order to overcome the destructive impact of heavy metals, numerous physical, chemical, and biological treatment techniques have been developed. Apart from numerous advantages of physical and chemical treatment, certain factors like difficulty in regeneration, by product and toxic sludge formation limits their application. At the same time, the lack of developed technologies and generation of toxic sludge limits the application of biological treatment methods. To overcome the aforementioned complexities, recent focus towards phycoremediation of heavy metals is unavoidable because of their natural origin. Phycoremediation is an efficient and economic technique used in biotransformation of polluting material present in water by using micro and macro algae. So this technique can be explored as a vibrant tool for reduction of heavy metal pollutants in wastewater.
