IMPACT OF TITANIUM DIOXIDE FACTORY EFFLUENT ON THE BIOCHEMICAL COMPOSITION OF THE FRESHWATER FISHERS OREOCHROMIS MOSSAMBICLISAND ETROPLLIS MACLILATLIS

VIJAYAMOHANAN AND G. ACHUTHAN NAIR

Abstract

Studies on the muscle and liver of the freshwater fishes Oreoclzromis mossambicus and Etroplus marulatus exposed for seven days in three sub-lethal concentrations (0.01%, 0.05, 0.10%) of Titanium dioxide industrial effluent revealed alterations in their water content, glycogen, protein, lipid and ash. A reduction in the pH and oxygen of the effluent-mixed media was evident when compared with the normal freshwater (control). A significant increase in the muscle and liver water content and glycogen, and a decrease in the protein and lipid were discernible in the effluent-treated fishes when compared with the control. A positive correlation was observed between concentrations of the effluent used and the ash content of fishes.
