Atrazine commonly used as a herbicide, contaminates the aquatic ecosystem as a toxic pollutant from agricultural and domestic washouts. The aim of the present study was to investigate the toxic effect of Atrazine on intestine tissues in the fish Channa punctatus exposed to sublethal concentration of 5 mg/L, 10 mg/L and 15 mg/L for 15 and 30 days respectively. The histological observations of the intestine showed deleterious effect of Atrazine exposure time, the intestine of C. punctatus showed many strong changes viz, rupturing of longitudinal and circular muscle layers, reduction of villi, Necrosis at the tips of villi and highly shrinkage of sub mucosa at the tips of the villi were observed, Distortion of goblet cells, Blood vessels and Loss of structural integrity of mucosal folds were also seen in the intestine of C. punctatus at higher exposure of Atrazine. This clearly demonstrates that the sublethal concentrations of Atrazine have a deleterious effect on the intestine of C. punctatus. So, the herbicide Atrazine can be considered as a potent toxic pollutant capable of destroying the balance of the aquatic ecosystem. : {"references": ["Bhatnagar, A., & Srivastava, S.K. (1992).
