Abstract
Dimethoate accumulation in liver and muscle tissues of a fresh-water f ish, Clarias bactrachus L., was measured by gas liquid chromatography. Fish were exposed to a sub-lethal concentration of the pesticide in t he laboratory water tank for a period of eight days. The accumulation increased up to two days, followed by decrease on the 4th and 8th days of exposure in both liver and muscle tissues. Maximum accumulation wa s found in liver. After eight days of exposure, fish were released int o pesticide-free water to study the rate of loss of the pesticide. It was found that liver and muscle tissues were cleared of dimethoate aft er four and eight days respectively.
