Influence of Sago Effluent on the Levels of the Enzyme Cholinesterase in the Brain Tissue of the Fresh Water Fish Clarias Batrachus

Ramesh. F, Nagarajan. K

Abstract


Monitoring of Cholinesterase activity has been widely used in aquatic and terrestrial systems as an indicator of pollutant exposure. The reports regarding impact of sago industry effluent on the level of ChE activity are very scanty. In this paper, an attempt has been made to investigate the in vitro impact of sago industry effluent upon the levels of ChE activity in the brain tissues of the fresh water fish, Clarias batrachus. The concentration chosen were 25%, 50% and 75% of treated sago effluent. The levels of ChE were decreased with increase in concentrations of the effluent. The control group recorded 268 u/l whereas the experimental groups such as 25%, 50% and 75% treated sago effluent showed 199u/l, 132u/l and 117u/l respectively.
