“…The Cu mean concentrations in turbot muscles were similar to the results of Lourenco et al [22] and Martinez et al [23], but compared with other studies [37,39], the values recorded in the present study were fourteen, respectively, thirty-three times lower. The Cu pathways in the body of turbot specimens from both analyzed groups are similar, with the highest concentrations recorded in liver tissue.…”

“…The mean of Ni concentration in turbot muscles was similar to the values found by Martinez et al [23], but more than thirty times lower than the concentrations reported by Nisbet et al [39] and Bat et al [37] for the Black Sea turbot meat. The pathways of Ni in the turbot body are similar both in male and female analyzed specimens, with the highest concentrations recorded in caudal fins.…”

“…The mean iron concentration in the muscle tissue, registered in the present study, is three times higher compared to the concentrations recorded by Lourenco et al [22], but at the same time, lower compared to other studies [36,37,39,40]. According to Lourenco et al [22], Fe was present in concentrations of approximately 5.0 µg•g −1 in marine fish species, which was similar to the present study results.…”

“…Among Black Sea demersal fish species, turbot presents interest in research for the biomonitoring of polychlorinated biphenyls [26,27]; food science preservation-freshness assessment of turbot by using different biochemical and proteomics methods [28]; molecular genetics [29]; ecology and behavior [30]; biomarker in oil pollution [31]; nitrite toxicity [32,33]; aquaculture [34]; heavy metal biomonitoring [35][36][37][38][39][40].…”

“…Several research papers conducted by Ergönül and Altindag, 2014 [40]; Nisbet et al, 2010 [39]; Das et al, 2009 [38]; Bat et al, 2006 [37]; Tuzen 2003Tuzen , 2009 [26,36] studied the concentration of potentially toxic metals and metalloids (Zn, Fe, Cu, Ni, Mn, Cr, Cd, Pb, As) in the Black Sea turbot muscle tissue captured in Turkish territorial marine waters. Other scientific articles realized by Manthey-Karl et al, 2016 [41], Martinez et al, 2010 [23] and Lourenco et al, 2012 [22] studied the concentration of essential macroelements (Ca, Mg, Na, K), microelements (Zn, Fe, Cu, Ni, Mn) and potentially toxic metals (Cd, Pb, As) in the muscle tissue of wild turbot captured in the Atlantic Ocean, respectively, in farmed turbot from Portugal.…”

This study investigates the influence of gender in the bioconcentration of essential and nonessential elements in different parts of Black Sea turbot (Psetta maxima maeotica) body, from an area considered under high anthropogenic pressure (the Constanta City Black Sea Coastal Area in Romania). A number of 13 elements (Ca, Mg, Na, K, Fe, Zn, Mn, Cu, Ni, Cr, As, Pb and Cd) were measured in various sample types: muscle, stomach, stomach content, intestine, intestine content, gonads, liver, spleen, gills and caudal fin. Turbot adults (4–5 years old) were separated, according to their gender, into two groups (20 males, 20 females, respectively), and a high total number of samples (1200 from both groups) were prepared and analyzed, in triplicate, with Flame Atomic Absorption Spectrometry and High-Resolution Continuum Source Atomic Absorption Spectrometry with Graphite Furnace techniques. The results were statistically analyzed in order to emphasize the bioconcentration of the determined elements in different tissues of wild turbot males vs. females, and also to contribute to an upgraded characterization of the Romanian Black Sea Coast, around Constanta City, in terms of heavy metals pollution. The essential elements Mg and Zn have different roles in the gonads of males and females, as they were the only elements with completely different patterns between the analyzed groups of specimens. The concentrations of studied elements in muscle were not similar with the data provided by literature, suggesting that chemistry of the habitat and food plays a major role in the availability of the metals in the body of analyzed fish species. The gender influenced the bioaccumulation process of all analyzed elements in most tissues since turbot male specimens accumulated higher concentration of metals compared to females. The highest bioaccumulation capacity in terms of Ca, Mg, Na, Ni, As, Zn and Cd was registered in caudal fin, liver and intestine tissues. Also, other elements such as K, Fe, Cu and Mn had the highest bioaccumulation in their muscle, spleen, liver and gills tissues. The concentrations of toxic metals in Black Sea turbot from this study were lower in the muscle samples compared with the studies conducted in Turkey, suggesting that the anthropogenic activity in the studied area did not pose a major impact upon the habitat contamination.
