Abstract :The concentrations of Ca, Mg, Fe, Zn, Cd, Pb, Cu and Cr in head bone stones of brown meager insert ignore into journalissuearticles values(Sciaena umbra); fishes and Bone ash 1400 standard reference material were determined by flame and electrothermal atomic absorption spectrometry. Flame atomic absorption spectrometer was used for the determination of Ca, Mg, Fe and Zn in samples by using lanthanum + potassium mixture. Electrothermal atomic absorption spectrometer was used for the determination of Cd, Pb, Cu and Cr in samples by using lanthanum +  palladium + ammonium dihydrogen phosphate as chemical modifier mixture. Limits of detection obtained are 2.5, 0.2, 11, 18, 1.1, 0.12, 1.21, 1.09, 0.12 9 g L -1 for Ca, Mg, Fe, Zn, Cd, Cu, Pb and Cr, respectively. Recovery tests for analytes in Bone ash 1400 and bone stone sample solutions were studied. Percent recoveries of analytes obtained are in the range of 96 – 102 %.
