Abstract
The aim of current research is to assess the harmful effect of agricultural pesticide on the internal organs of non-target organisms like fish using Scanning Electron Microscope. Intended to kill harmful pests and insects, these chemicals directly affect many non target organisms which live in nearby habitats of agricultural fields. These chemicals easily get access into nearby ponds and rivers and affect aquatic life. Current investigation reveals harmful effects of Chlorpyrifos 50% + Cypermethrin 5% EC on liver and kidney of Clarias batrachus exposed to sub-lethal cocentration of the pesticide for 30 days. Observed under Scanning Electron Microscope, the effect include lost hepatic architecture, hepatocyte degeneration, shrunken glomerulus, damaged Bowman’s capsule, damaged tubules and spills of RBC in the tissue section. Consumption of such fishes also puts human under severe health risks.
Keywords: Liver, kidney, Clarias batrachus, pesticide, biodiversity, scanning electron microscope.
