Abstract :

The present investigation was carried out to study the effect of Chromium on total ATPases, in selected tissues of a fresh water fish Labeo rohita. The alterations in ATPase activity on exposure to sub lethal concentration (1/10th of LC50/96 hrs) of chromium for 7days and 30 days was investigated in the present study. Results revealed statically significant (p<0.05) decrease in total ATPases in various tissues of experimental animals when compared to the control with an increase in exposure days. The inhibition of ATPase activity could change the sodium and potassium gradients across the cell memane and disrupts the ionic movement in the neuronal cells. The results suggest that ATPase has a particular sensitivity to chromium.
