Pesticide accumulates in aquatic ecosystems and exerts toxic effects on aquatic animals. In this study, stress parameters and tissue histopathology under acute diazinon exposure were investigated in fish, scat (Scatophagus argus). Spotted scat was exposed to different diazinon concentrations (0, 10, 20, 30 μg L(-1)) for 24, 48, 72, 96 h. Cortisol and glucose levels showed a significant increase after exposure to different diazinon concentration with increase in exposure time. The electrolytes (K(+), Cl(-), Ca(2+), Na(+)) and glucose were differentially affected during the exposure to diazinon. Gill and kidney tissues showed many histopathological changes in diazinon-exposed fish. These results suggest that the release of spotted scat (S. argus) into the diazinon-contaminated regions may alter their physiology and jeopardize their survival.
农药在水生生态系统中积累，并对水生动物产生毒性作用。在本研究中，对大眼鲳（Scatophagus argus）进行急性二嗪农暴露，研究其应激参数和组织病理学变化。将斑鲳鲹暴露于不同浓度（0、10、20、30 μg L(-1)）的二嗪农中24、48、72、96小时。随着暴露时间的增加，暴露于不同浓度二嗪农后，皮质醇和葡萄糖水平显著升高。在暴露于二嗪农期间，电解质（K(+)、Cl(-)、Ca(2+)、Na(+)）和葡萄糖受到不同程度的影响。鳃和肾脏组织在暴露于二嗪农的鱼中显示出许多组织病理学变化。这些结果表明，将斑鲳鲹（S. argus）放归受二嗪农污染的区域可能会改变它们的生理机能并危及它们的生存。
