Abstract:
Triclosan (2,4,4’ –trichloro-2’-hydroxydiphenyl ether)is a chlorinated aromatic compound, used as a synthetic broad-spectrum antimicrobial agent in many personal care products like soaps, hand-washes, toothpastes, mouth washes, deodorants, antiperspirants and shaving creams. The products that contain Triclosan wash down through drains and into water systems and it had become a common contaminant. Triclosan can persist in the environment and exhibit toxicity towards a number of aquatic organisms. Fishes are the most widely distributed organisms and play a central role in aquatic ecosystems. Hence, understanding toxic responses in fish is of high ecological relevance. To assess the aquatic toxicity caused by Triclosan in fresh water fish, Channa punctatus the total carbohydrate modifications were studied. The fishes were exposed to sub lethal and lethal concentrations for 96 hours. Estimation of total carbohydrates in the five tissues-muscles, gill, liver, kidney and brain was done by Carroll et al., method. The total carbohydrate content decreased with the increase of Triclosan concentration. The total carbohydrate levels depletion was observed maximum in Kidney as 36.31% and minimum percentage in brain as 18.93% in sub lethal concentration and maximum in Liver as 42.37% and minimum in Gill as 30.17% in lethal concentrations when compared with the control.The levels of total carbohydrates were found to decrease because of utilization of carbohydrates to meet the energy demands during stress conditions. It was observed that low concentration of Triclosan (0.37 ppm) is also very toxic and causes alterations in vital organs of fish, Channa punctatus
