The biochemical component like glycogen was estimated quantitatively in the tissues of liver and kidney of control and arsenic treated fish. The experimental fish were exposed to lower and higher sublethal concentrations (one-tenth and one-third of the 96 hr LC50 value) of arsenic for a period of 7, 14, 21 and 28 days. In both the tissues a significant reduction in glycogen level has been noticed. Maximum reduction was observed on the 28th day of exposure.

Abstract


The biochemical component like glycogen was estimated quantitatively in the tissues of liver and kidney of control and arsenic treated fish. The experimental fish were exposed to lower and higher sublethal concentrations (one-tenth and one-third of the 96 hr LC50 value) of arsenic for a period of 7, 14, 21 and 28 days. In both the tissues a significant reduction in glycogen level has been noticed. Maximum reduction was observed on the 28th day of exposure.
