Bioaccumulation and Distribution of Heavy Metals in Different Soft Body Tissues of The Freshwater Bivalve, Parreysia corrugata

Waykar Bhalchandra, Shinde Satish

Abstract :

The freshwater bivalve, Parreysia corrugata were exposed to chronic concentration (LC50/10 96 h) of arsenic (0.1719 ppm), cadmium (0.1284 ppm), copper (0.033 ppm), lead (1.50 ppm) and zinc (1.8589 ppm) separately for 20 days. After 10 and 20 days of exposure animals were dissected and their mantle, gills, digestive glands and whole soft body tissues were removed and dried in oven at 80oC. The heavy metal concentrations were determined from dry powder of each tissue by using AAS. The obtained data revealed a significant increase in metal concentration in all soft body tissues of experimental bivalves with increase in exposure period as compared to the bivalves maintained as control. It was observed that different concentration of heavy metals found in different soft body tissues, this indicates different metal regulation and binding sites in these organs. It was also observed that digestive glands accumulated higher concentration of As (52.81 µg/g), Cd (71.18 µg/g), Cu (80.28 µg/g), Pb (286.08 µg/g) and Zn (1532µg/g) of dry tissue weight as compared to other studied tissues. Therefore, digestive glands of Parreysia corrugata is being proposed as bioindicator organ for monitoring of As, Cd, Cu, Pb and Zn metal pollution in freshwater ecosystem.
