In vivo effects of trivalent and hexavalent chromium on renal and hepatic atpases of a freshwater teleost Anabas scandens.

The in vivo toxic effect of trivalent and hexavalent chromium (25 mg/L) on the renal and hepatic tissue ATPases of an edible teleost Anabas scandens was studied. In an exposure span of 30 days Na(+)-K(+) ATPase activity exhibited a progressive inhibition in the kidney, but marked inhibition in Na(+)-K(+) ATPase activity was observed in the liver. Mg(2+) ATPase activity, however, exhibited an elevation on early exposures, with a later inhibition.
