Abstract: The present study deals with the bioaccumulation of heavy metals in the freshwater lamellibranch mollusks inhabiting in the Krishna river at Ankali. The bivalve, Lamellidens corrianus (Lea), was selected in the present study. This species of mollusks was subjected for detection of heavy metals such as Zinc, Nickel, Lead and Aluminium from various soft tissues such as mantle, gill, siphon, foot, hepatopancreas and gonads. The work was carried out seasonally for the period from January 2013 to December 2013 and values were recorded in ppm. In general, accumulation of Zn was maximum in gills, while minimum in foot in different seasons. Similarly accumulation of Ni, Pb and Al was maximum in gonads whereas, it was minimum in siphon in different seasons.
