Fluoride induced changes in protein metabolism in the tissues of freshwater crab Barytelphusa guerini.
Exposure of the freshwater field crab Barytelphusa guerini to a sublethal concentration of NaF (30 mg litre(-1)) caused significant alterations in protein metabolism. After an exposure time of 15 days, the crab was found to have a marked depletion of total protein and free amino acid content. A significant elevation in transaminases, Aspartate aminotransferase (AAT) and Alanine aminotransferase (ALAT), and Glutamate dehydrogenase (GDH) activities was reflected in the free amino acid levels of the tissues.
