CHLORPYRIFOS INDUCED TOXIC IMPACTS ON GLYCOGEN CONTENT IN GILL, LIVER, KIDNEY,BRAIN AND MUSCLE OF FISH,CHANNA PUNCTATUS

Abstract

The Channa punctatus was exposed to various concentrations of chlorpyrifos 1.7, 1.8 and 1.9 ppm with contact time of 15, 30 and 45 days. After stipulated time, glycogen content in gill, liver, kidney, brain and muscle of treated fish found to be dropped after pesticide introduction. The efficiency of chlorpyrifos in the destruction of total glycogen content was evaluated by Langmuir and Freundlich isotherm models in relations of Qm and Kf The spontaneity of the reaction in between chlorpyrifos and fish glycogen was determined by Gibb’s free energy equation. The present analysis reports the metabolic dysfunction in response to pesticide toxicity in the fish. The glycogen level was estimated by method of Kemp and Kitsvan Heijhinger and the data obtained were analyzed by applying Langmuir and Freundlich isotherms and thermodynamic analyses. The result shows deteriorated levels of glycogen during all the exposure periods when compared with control. The results of the current study show the toxic nature of the chlorpyrifos on the glycogen content in gill, liver, kidney, brain and muscle of treated fish.
