Effects of rogar and endosulfan on the metabolism of fresh water sponge (Spongilla lacustris)

Spongilla lacustris were exposed to sub lethal concentrations of pesticides, rogar and endosulfan for one month period. Metabolites like carbohydrates, protein and enzymes like those that peroxidase and carbonic anhydrase were estimated in the experimental and control animals. The results show, depletion of carbohydrates while protein elevated as the days progressed. Similarly an enzyme activity found to be decreased in exposed Spongilla lacustris.
