Abstract: The aim of present study is to determine the heavy metal pollution (Zn, Pb, Cu, Cd, As) in Godavari river at Paithan. Heavy metal concentrations in surface water, soil sediment and different soft body tissues (mantle, gills, digestive glands and whole soft body tissue) of freshwater bivalve, Lamellidens corrianus, Lamellidens marginalis and Indonaia caeruleus were investigated in samples collected from Godavari river at Paithan. In the present study heavy metal concentrations in different soft body tissues of bivalves was highest than heavy metal concentrations in surface water and soil sediment. The digestive gland accumulated highest concentrations of heavy metals as compared to other studied organs in three bivalve species. The bioaccumulation of heavy metals in different soft tissues of bivalve can be used for the detection of polluted area.

Key words: Heavy metals, Godavari river, bivalves, bioaccumulation.
