ABSTRACT

These days, water contamination is a global problem. Hazardous chemical contamination from agricultural runoff, household and industrial wastewater is the primary cause of water pollution. Pesticides are one of the main compounds found in agricultural runoff, and they are crucial in boosting agricultural output by managing pests. However, these pesticides cause serious harm to non-target creatures in both terrestrial and aquatic ecosystems. It is therefore essential to thoroughly research the histology of fish and other aquatic species. Histological examination seems to be an extremely sensitive measure and is essential for identifying potential cellular alterations in vital organs. The current research investigated the toxic effects ofdeltamethrin at 1/20th and 1/10th of 96hrs LC50 value for a period of 28 days on kidney of common carp [Cyprinus carpio]. Various alterations were observed after the exposure of pesticide in treated fish in comparison to control. Histological changes observed after the exposure of deltamethrin are damaged glomerulus, degenerated renal tubules, melanomacrophage centers, degeneration of epithelial cells, narrow lumen of tubules, pyknotic nuclei, dilation of Bowman’s space, infiltration of blood cells and necrosis in the epithelial lining of various structures.

Key words : pesticides, synthetic pyrethroids, deltamethrin, common carp, kidney, histology.
