Abstract:
:Pesticide mixtures are common in the streams of agricultural or urban catchments. Individual and cartel toxicity of four different pesticides, namely Endosulfan, Carbofuran, Methyl parathion and Cypermethrin were studied. Sub acute exposure (1/10th of LC50) for 1, 7, 15, 30 and 60 days in Clarias batrachus active tissues such as brain, gills, blood and liver were evaluated. Growth, hepatosomatic index and survival performance were decreased, inhibition of brain acetylcholinesterase, gills Na(+)/K(+) ATPase activities, and abnormal behavior are noticed. The characteristics of the blood respiratory burst activity, erythrocyte count, contents of hematocrit and hemoglobin are dwindled. Plasma total proteins and liver glycogen decreased whereas blood glucose and serum creatinine, triglycerides are elevated. The immunological attributes such as white blood cell count was elevated, whereas albumin, globulins and lysozyme activity significantly decreased. Hepatic superoxide dismutase, catalase and glutathione S-transferase activities and lipid peroxidation levels are elevated, whereas glutathione peroxidase and glutathione are reduced. Toxicity effect of pesticides reached to a crest on 30th day and showed a descent thereafter except in endosulfan which mounted its detrimental effect throughout the experimental period. Toxicity trends of the present study are determined to be highest in Mix group followed by cypermethrin, methyl parathion and carbofuran. Indiscriminate application of these chemicals pose a toxic threat to non-target organisms, damage the ecosystems and jeopardizes human health.
