Toxic Elements in Edible Mollusks from Igneada Coasts of the Black Sea, Turkey
Bat, Levent,Sahin, Fatih,Oztekin, Aysah Korea FoodHealth Convergence Association 2018 식품보건융합연구 (KJFHC) Vol.4 No.3
In this present work, the amounts of toxic elements were determined in the soft tissues of mollusks (Mytilus galloprovincialis and Rapana venosa) collected from Igneada shores of the Black Sea where suggested as Marine Protection Area (MPA). M. galloprovincialis accumulated the highest amounts of Cd in winter, while the highest amounts of Cd and Hg were detected in R. venosa in winter and autumn. The concentrations of toxic elements found in the soft tissues of mollusks varied for Cd: 0.07-0.14, Hg: 0.03-0.44 and Pb: 0.09-0.21 mg/g dry wt. The estimated levels of all non-essential metals in the present work were lower than the limits permitted by European Community Regulation (EU) and the Turkish Food Codex (TFC). The estimated weekly intakes (EWI) and daily intakes (EDI) of all the through consumption of these seafood by Turkish people in the Igneada coasts of the Black Sea were quite below the permissible tolerable weekly/daily intakes for 70 kg person (PTWI / PTDI) set by FAO/WHO. As results, it can be concluded that no hazard effects on people health would be raised at present from the consumption of these mollusks' species.

The levels of five heavy metals (mercury, cadmium, lead, copper and zinc) were analyzed in edible tissues of Lophius piscatorius Linnaeus, 1758 marketed in Sinop coasts of the Black Sea by using inductively coupled plasma mass spectrometry. With the present study, heavy metal values of this fish in the Black Sea were examined for the first time. The mean concentrations in mg kg<sup>-1</sup> wet wt. of Hg, Cd, Pb, Cu and Zn were 0.022, 0.009, 0.035, 6.3 and 16 mg kg<sup>-1</sup> wet wt., respectively. The results of the present study indicate that the consumption of muscle from anglerfish can be considered safe in terms of permissible legal limits. It is clear that, Zn showed the high accumulation in muscle tissue followed by Cu, while non-essential metals Hg, Cd and Pb showed the low accumulation. This could be explained by the fact that Zn and Cu are essential elements in the bodies of living organisms and has an important role in different physiological processes. In the present study, heavy metal levels in angler fish were low. Likewise, the calculated HI values were lower than one. In conclusion, the results of the present study indicate that the consumption of muscle from anglerfish can be considered safe in terms of permissible legal limits and hazard index values.
