Alterations in protein content was studied in freshwater bivalve,Pila globosa exposed to three different concentrations (viz., 0.002%, 0.005% and 0.01%) of cadmium chloride (CdCl2) in mantle, foot, and liver at three different fixation intervals (viz., 7d, 14d and 21d). There was a significant decrease in protein content in all the three vital organs of P. globosa under experimentation as the concentration of CdCl2 increases. The depletion of protein content was due to the toxicity of CdCl2 and this toxicological stress might have increased the proteolysis activities in the cells.
