The levels of the several metals were determined in the fish species collected in the İznik and Uluabat lakes. The mean cadmium, mercury. lead, copper, iron and zinc residue levels in fish were found as 0.084, 0.181, 0.387, 2.496, 13.857 and 11.770 ppm in İznik lake; 0.101, 0.255, 0.407, 2.081, 11.251 and 16.670 ppm in Uluabat lake respectively. Based on the same fish species of carp and rudd, the differences in cadmium. mercury, lead, and copper residues were not significant; in iron and zinc residues were found to be significant (p < 0.01 and p < 0.001 respectively).
