Abstract
This study was carried out to provide information on heavy metal concentrations in the marine organisms as two fish species (Raja clavata and Trachurus trachurus), one mussel species (Mytilus galloprovincialis) and one seaweed species (Ulva lactuca). These marine species obtained from coast of Sinop province in the Black Sea. The concentrations of 23 heavy metals (Be, Na, Mg, Al, K, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Cd, Cs, Ba, Hg, Ti, Pb and U) were determined in the muscles of M. galloprovincialis and T. trachurus, in the whole U. lactuca and in the muscles, heart and liver of R. clavata. Twelve of the 23 metals (Be, Al, V, Cr, Co, Ni, Cd, Cs, Ba, Hg, Ti, Pb and U) levels were estimated very lower values between <= 0.001 - 0.08 mg/kg in the muscles, heart and liver in R. clavata. The levels of heavy metals varied significantly in tissues of R. clavata. Statistically differences were obtained for different metals among the muscles, heart and liver. The determined highest level of metals in muscles was Na, Mg, Sr, in heart K, Fe, Se and in liver Mn, Cu, Zn, As, Hg (P < 0.05). Seven of the 23 metals levels were estimated higher values K > Na > Al > Fe > Sr > Zn > Mn in U lactuca. Five of the 23 metals levels were estimated higher values K > Na > Mg > Zn > Fe in T. trachurus. Six of the 23 metals levels were estimated higher values Na > K > Mg > Al >Fe > Sr in M. galloprovincialis. The results showed that K, Na, Mg, Fe, Zn and Al were the highest levels in the muscles of M. galloprovincialis, T. trachurus and U. lactuca. Our results showed that studied marine organism contained different mean concentrations of heavy metal in whole body and tissues. The levels of heavy metals varied significantly among fish species and tissues. As expected, muscles always possessed the lowest concentrations of heavy metal levels within accepted by the international legislation limits and are safe for human consumption.
