Özet
The investigation of whether public health is affected by the heavy metal accumulation in the fish species that are especially endemic and economically important to the Black Sea is of great importance. These types of studies provide scientific data for the evaluation of the impact of heavy metal accumulation both on environmental health and public health. Thus, this study examines the accumulation concentrations of 10 different heavy metals comprising cadmium (Cd), chromium (Cr), nickel (Ni), lead (Pb), manganese (Mn), iron (Fe), cobalt (Co), copper (Cu), zinc (Zn), and mercury (Hg) in the muscle tissue, gill, gonad, liver, and liverexcluded visceral organs of the red mullet (Mullus barbatus) samples that were collected by hunting from the coasts of Sinop (the Black Sea), Turkey. The species that was selected for the study is economically important and endemic to the area. The study contributes uniquely to the literature for its separate examination of the heavy metal accumulation in various tissues, instead of whole fish samples or a limited number of tissues. Another contribution of the study is its examination of the heavy metal accumulation in the gonad to investigate the sustainability of the reproduction of the species. The fmdings of this investigation offer important implications for the reproduction of the species and the sustainability of the population. Trace metals in red mullet (Mullus barbatus), from the Middle Black Sea were determined and compared with the permitted limits. The maximum and minimum concentrations (mu g.kg(-1) dry wt) in red mullet, muscle samples were found as 9,23 +/- 1,46 for Mn, 20,87 +/- 3,92 for Zn, 0,69 +/- 0,02 for Cd,<0,64 for Cr,<0,48 for Co,<1,02 for Ni,<0,82 for Cu,<4,71 for Pb, 189,65 +/- 17,42 for Fe respectively and the value of Hg could not be detected; the results were below the measurement limit. The results of the study revealed that the differences in the metal concentrations in the muscle tissue, gill, gonad, liver, and liver-excluded visceral organs of the species were statistically significant. The comparison of the results for the metal concentrations to the limit values specified by various organizations such as the Turkish Food Codex (TFC, 2011), European Commission Regulations (EC, 2006), and Food and Agriculture Organization (FAO, 1983) revealed that the heavy metal accumulation levels in the muscle tissue of the species were below the limit values that could threaten human health.
