title: Impact of sodium arsenite on certain biomolecules of nutritional importance on the edible components of the economically important catfish C. batrachus (Linn.).
abstract: The toxicity of sublethal concentration (1 mg/L; 5% of 96hLC(50) value) of sodium arsenite (NaAsO(2)) for 60 days on certain biomolecules (proteins, lipids, and water) of five vital organ systems (muscles, liver, brain, skin, and gills) of Clarias batrachus were analyzed to evaluate the damage rendered to the food value of the fish. Arsenic disturbs the equilibrium existing between these nutritionally important macromolecules in all the organ systems. These tissues showed marked fluctuations in their protein (1.56 ± 0.79% in gills to 4.46 ± 1.54% in muscles), lipid (1.79 ± 0.89% in skins to 4.81 ± 1.15% in brain tissue) and water contents (65.84 ± 1.01% in brain to 78.66 ± 0.37% in gills).
