Abstract
Clastogenic effects of home wastes and agricultural contaminates of Lake Uluabat ("40 degrees 11'41.38"N, "28 degrees 27'08.40"E) were investigated in peripheral erythrocytes of Cyprinus carpio. Examination of blood smears showed that the formation of micronuclei was significantly increased (f = 21.89, df = 3) with p value > 0.001during one year, and where more abundant in the same species of fish compared to the control. This increase in the formation of micronucleus indicates that home waste and agricultural pollution increase the clastogenic effects on peripheral erythrocytes of C. carpio and may have similar effects on the human population located around the lake and consume the fishes.
