Assessment of element concentrations in widely consumed cultured fish in Turkey

14477

Fish farms are able to produce high amount of quality food for human consumption. On the other hand, heavy metal pollution in aquatic ecosystems can be a serious problem. In this study, some micronutrients and non-essential element concentrations in edible tissue of three cultured fish species, (Oncoryhynicus mykiss (rainbow trout), Dicentrarchus labrax (seabass) and Sparus aurata (seabream)) which were taken from primary fish markets of Kocaeli province between December 2011 and January 2013 were monitored. Concentrations of Ca, K, Mg, Na, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Pb, Se, and Zn were analyzed using ICP-MS and annual intakes of these elements via consumption of fish were calculated for inhabitants. None of the element concentrations in the fish muscle tissue exceeded the threshold levels which were suggested by Food and Agriculture Organization and by the Turkish Food Codex and based on calculated element intake rates, there were no risk for humans to consume these farm fishes. Principal Component Analysis reveals that elements can be grouped under three components in cultured marine fish muscle tissue.
