Bioaccumulation of heavy metals in water and algae of mukkombu in the river cauvery system, Tiruchirappalli district, Tamil Nadu, India

Today water discharges from industries are the major causes of water pollution resulting in destabilized ecosystems. Hence, it is necessary to monitor the levels of these pollutants as well as develop technologies for the treatment of waste water. Hence, the present study was attempted to analyse the commonly occurring heavy metals in water and organisms in two stations, Musiri and Mukkombu of the River Cauvery. Results indicate that iron recorded the highest levels followed by zinc, copper, lead and cadmium with regard to metal content in organisms, Nitzshua sigma recorded the least metal content, while Spirogyra quininarecorded highest Cu content and Oscillatorialimosa the highest Cd content. However, Chlorella vulgaris recorded the highest content for Pb, Zn and Fe for both the stations.Among the two Stations, Station-II (Mukkombu) recorded the highest concentration of all the metals in both water as well as organisms. Thus, it is obvious that metals are taken up by algae. | Bioaccumulation of heavy metals in water and algae of mukkombu in the river cauvery system, Tiruchirappalli district, Tamil Nadu, India
