HISTOPATHOLOGICAL EFFECTS OF GLYPHOSATE IN THE GILL, LIVER AND KIDNEY OF THE FRESH WATER FISH, CYPRINUS CARPIO

The common carp, Cyprinus carpio were exposed to 1/10th of 96 hours LC50 concentration (0.02ppm) of glyphosate for 10, 20 and 30 days. Gill, liver and Kidney tissues of Fresh water fish, Cyprinus carpio were examined after exposure to sublethal concentration of Glyphosate. The gill showed histopathological changes like necrosis, vacuolar degeneration, fusion and atrophy of primary and secondary gill lamellae. Degeneration of cytoplasm in hepatocytes, atrophy, formation of vacuoles, rupture in blood vessels and disposition of hepatic cords were the histopathological changes noticed in the liver. The changes in the kidney include necrosis, cellular hypertrophy, granular cytoplasm and swelling of renal tubules.
