The levels of trace metals of front (F) and rear (R) dorsal ordinary muscles (dom) of wild and farmed bluefin tuna (BFT) were determined by atomic absorption spectrometry. Wilds were obtained from Antalya Bay and farmed were taken from a fish farm in Ildir Bay (Izmir), during spring to early summer. The accuracy of the method was checked standard reference material (NRCC-DORM-2 Dogfish Muscle). Mean trace element content of the wild samples (Fdom and Rdom, respectively) was found as: Cu, 0.790 and 0.591; Mn, 0.084 and 0.096; Ni, 0.101 and 0.124; Zn, 4.788 and 5.577; Fe, 7.670 and 9.222 (mu g g(-1) wet wt.). Values for farmed were detected as Cu, 0.581 and 0.453; Mn, 0.111 and 0.139; Ni, 0.072 and 0.092; Zn, 4.631 and 3.380; Fe, 4.957 and 7.156 (mu g g(-1) wet wt.). The results were compared with literature values. Crown Copyright (C) 2011 Published by Elsevier Ltd. All rights reserved.
