This research was conducted for evaluation of the effect of pollutants of Tigris on some parameters of oxidative stress incommon carp. In addition to detection of Glutathione, Malondialdehyde, vitamins E and C and the results were compared withcontrol group. The results revealed that the presence of congestion on blood vessels in kidney with vacuolar degeneration inhepatic cells with infiltration of inflammatory cells and swelling and fatty change in the epithelial cells lining the renal tubulesin addition to coagulative necrosis with infiltration of inflammatory cells in the interstitial tissue of kidney. Furthermore fattychange in cardiac muscles with infiltration of inflammatory cells and congestion of blood vessels in heart were observed. Thestatistical analysis referred to a significant decrease (P≤0.05) in glutathione and increase in the malondialdehydeconcentrations levels for the most tissues but there was no difference in E and C vitamins except that of the kidney which showa decrease in C vitamin level. It is concluded from the present study that there is a worse effect of pollutants in river of Tigrison the levels of lipid peroxidation indicators for carp fish tissues naturally exposed to those pollutants which may affects thenutritional and hygienic values of these fishes.
