Effect of Chlorpyriphos 20% EC on Respiratory Physiology of Mosquito Fish, Gambusia Affinis
Authors(3) :-Vandana Bhavare, Komal Bhagwat, Rajeshwari Oza The enormous use of pesticides in the agricultural system, leads to deposition of large amount of toxicant which produces adverse effects on human as well as fresh water organisms. The respiration is an important physiological activity in all living organism These pesticides decreases the level of dissolved oxygen in the water bodies and leads to changes in the respiratory physiology of the aquatic organisms. The pesticides used in the fields get collected in the water bodies enter into the body of aquatic organisms like fish and may cause adverse effects on it. The oxygen consumption tendency is decreased when the time of exposure to toxicant is increased. The reduced O2 consumption could be due to gill damage. The total O2 consumption is one of the indicators of the general wellbeing of the fish. The study reveals the effect of pesticide Chlorpyriphos 20 % EC on the respiratory physiology of mosquito fish Gambusia affinis. The O2 consumption level of fish Gambusia affinis was observed in the different concentration of (0.02, 0.04, 0.06, 0.08 ppm) at different time of exposure periods (24, 48, 72 & 96 hrs). The oxygen consumption exhibited decreasing trend in treated group up to 96hrs as compared with control group. The present study has clearly showed that commonly used pesticide in agriculture, chlorpyriphos 20% EC affects the oxygen consumption of mosquito fish, Gambusia affinis under all exposed concentration. The oxygen consumption level of the exposed fish at different times of exposure (24, 48, 72 and 96 hrs.) was found to be declined gradually till the end of exposure period (96hrs), the gradual decline was attributed to the interference of pesticide with oxidative metabolism. This pesticide caused respiratory distress, decreased level of oxygen consumption in fish Gambusia affinis, which suggested that Chlorpyriphos 20% EC is highly toxic to fish. Possibility of water pollution by this pesticide can be monitored through adapting proper assessment mechanism.
