Heavy metal pollution has drawn increasing attention worldwide owing to a dramatic increase in anthropogenic heavy metals in ecosystems through air, water and soil. Mainstream land and water area in Kerala are polluted with heavy metals due to industrial effluents. Periyar River is the longest river and the river with the largest discharge potential in the Indian state of Kerala. Marine micro and macro organisms contains numerous bioactive compounds and those organisms were involved in the bioaccumulation . Cyanobacteria or Blue green algal cells have developed natural methods of responding to metals such as copper, lead, and cadmium through passive accumulation in cells and through surface binding to various functional groups. They have also been found to remove harmful metals from the environment. The present review article mainly focused on the Phyco remediation potential of blue green algae based heavy metal removal in Periyar River which will be a promising tool in waste water treatment on further study.
