Abstract
The Freshwater bivalve Lamellidens marginalis from the Godavari river at Paithan were exposed to lethal and sublethal concentration (1.9 ppm and 1.0 ppm) of Copper Sulphate as acute and chronic treatment. The amylase activity in the control bivalves L. marginalis was 7.1281 mg. of maltose/mg protein!' hr. of room temperature. In the present investigation heavy metal CuSo4showed decrease in amylase activity 2.223 mg. at maltose/mg protein/hr at the end of 72 hrs.
