Abstract

Heavy metals are known inducers of oxidative stress by directly producing reactive oxygen species (ROS), which leads to formation of LPO and modulate the activities of antioxidant enzymes and causes disturbances in metabolic functions. The modulation of antioxidant enzyme system like superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione S-transferase (GST) and concentration of reduced glutathione (GSH) are reported. Accumulated heavy metals also cause conflict in metabolic functions, trigger detoxifying enzymes, and antioxidant system damage leads to oxidative stress and causes damage to protein and other biochemical constituents. In the present investigation, the heavy metals Zn, Cu, Pb and Cd were determined in surface water and the freshwater bivalve Lamellidens marginalis collected from Girna, Ozarkhed, Chankapur and Gangapur reservoirs of Nasik district during summer, monsoon and winter seasons to study their effect on the activity of antioxidant enzymes and biochemical constituents like protein and ascorbic acid in soft body tissues of the bivalve.
