The Black Sea Turbot (BST) is one of the most valuable fish species exploited within the fisheries activities conducted in the Black Sea, due to market demand and high selling prices. However, due to the anthropogenic pressure exercised on the Black Sea, BST is prone to accumulate different contaminants such as heavy metals. The risk of heavy metals transfer to the human consumer, through fish consumption, is possible. Thus, constant evaluation of the biomass is needed in order to avoid consumer intoxication. It is well known that different metals manifest competing behaviour for binding spots when accumulating in biota. Therefore, the present study aims to evaluate the concentration of macro- (Ca, Mg, K, Na) and micro-elements (Fe, Zn, Cu, Ni, Cr, Mn, Co, Cd, Pb) in BST muscle tissue collected from the Romanian Black Sea sector and to determine the correlation relationship between them (Pearson coefficient). The following accumulation trend in BST muscle was identified: Na>K>Ca>Mg>Zn>Fe>Cu>Mn>Ni>Cd>Pb>Cr>Co.
