Histopathological Effects Of Black Molly Fish Poecilia latipinna Exposed By Trifluralin

Sublethal concentrations of herbicide trifluralin were investigated with black molly fish Poecilia latipinna. Fish were exposed to ( 0.09,0.18,0.28 trifluralin m/L) for 30 days toxicity test. Trifluralin caused many histopathological effects in gill, liver and kidney. Gill disorders include hypertrophy of chloride cells, hyperplasia, lifting of epithelial cells and fusion of secondary lamellae. Liver suffered from herbicide as swelling of hepatocytes, infiltration of leukocytes, necrosis and fibrosis. Kidney also affected by trifluralin,Degeneration, hypertrophied cells and narrowing of the tubular lumen, shrinkage of the glomerulus, hyperplasia, hyalinization, Atrophied of tubular cells with Oedema
