Abstract :In this study, cadmium concantrations in the muscle, brain, and bone tissues of Tilapia nilotica exposed to 0.1, 0.5 and 1.0 ppm of cadmium insert ignore into journalissuearticles values(Cd); for 15, 30 and 60 days were examined. At the end of assigned periods, the concentrations of cadmium in the tissues were measured by Atomic Absorbtion Spectrofotometer insert ignore into journalissuearticles values(AAS);. The concentration of the cadmium in the muscle tissue was not statistically significiant in relation to medium concentration and the period. However, cadmium accumulations in the brain and bone insert ignore into journalissuearticles values(i.e. backbone); tissues increased significantly in accordance rise in the environmental concentrations and time. Cadmium accumulations in the brain tissue reached 14.35 and 18.57 ppm, which were high level, at the test concentrations of 0.5 and 1.0 ppm in the sixtieth day. The ratios of the total cadmium in the tissues, examined in the study, were analysed 16, 36 and 48 % in the muscle, bone and brain respectivley.
