In the present work the induction of micronuclei (MNi) and nuclear abnormalities (NAs) in erythrocytes and Cu and Cd
accumulation in whole body of Gambusia affinis were studied. Fish were exposed to two different Cu and Cd concentrations,
0.1 ppm and 1 ppm, for 1 and 2 weeks periods and to Cu-Cd combination (0.1 ppm Cu + 0.1 ppm Cd) for 2 weeks period
using a semi-static renewal system. Micronucleus and nuclear abnormality analysis were carried out on peripheral blood
erythrocytes. When fishes were exposed Cu and Cd in combination, Cu accumulation was increased compared to their singly
(0.1 ppm) exposed concentrations. Micronucleus and nuclear abnormality analysis tests revealed that, although Cu and Cd did
not significantly increase micronuclei frequency, nuclear abnormalities were significantly induced compared to control
groups.
