Özet

The aim of the present study was to determine the levels of chromium in the liver, gill and muscle tissues of Oreochromis niloticus after exposing the animals to 1.0, 2.0 and 4.0 ppm chromium over 96 h. Metal levels in the tissues studied were determined using atomic absorbrtion techniques. Although, some behavioral disturbances were observed in the chromium exposed fish at the beginning of experiments, no mortalities were observed at the end of 96 h. Exposure to chromium increased tissue levels of the metal except the muscle tissue while tissue accumulation increased with increasing concentration of the metal in the medium. Maximum accumulation was observed in the gill tissue at the lowest concentration tested, whereas accumulation was higher in the liver tissue at 2.0 and 4.0 ppm Cr.
