“…As in the previous results, this supports the notion that the polar features could be very similar to PCBs found in fish tissue. [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Moreover, the ice-cold condition was strongly suggested to remove the heat disturbance.…”

Optimized Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) pretreatment methods for determination of six polychlorinated biphenyls (PCBs) residues in fish and aquatic invertebrates samples were investigated. Large volume injection (LVI) coupled gas chromatography tandem mass spectrometry (GC-MS/MS) with selected reaction monitoring (SRM) was used to provide a very sensitive and selective means of analyzing PCBs via internal calibration. Three analytical processes were validated and compared, and the florisil Celite ® 545 pretreatment method was selected. Performance characteristics, such as linearity, limit of detection (LOD), limit of quantization (LOQ), recovery and precision (relative standard deviation, RSD) were studied. The method was applied to 233 samples obtained from local markets, which was useful and thus suggested that the method could serve as a screening model for PCB residues analysis.

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.

“…Some organochlorine compounds are persistent and although they have been banned, continue to be widespread and accumulate in the marine ecosystem (Turner, 1986). Polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane and its metabolites (DDTs) are well known as persistent substances in the aquatic environment and seafood rapidly accumulates these compounds both through their feeding behavior and from the surrounding environment (Antunes and Gil, 2004;Bordajandi, 2006;Stancheva, 2017b). These toxic substances are listed as persistent organic pollutants (POPs) in The Stockholm Convention (UNEP, 2001).…”

The presence of polychlorinated biphenyl congeners, organochlorine pesticides and marine biotoxins in the marine environment is important for the evaluation of a potential risk to human health. The purpose of the present study was to determine concentrations of polychlorinated biphenyl congeners (PCBs) and organochlorine pesticides (DDT and its metabolites) in three fish species and mussels (Mytilus galloprovincialis) and marine biotoxins in mussels from the Black Sea, Bulgaria. Concentration of six Indicator PCB congeners, DDT and its metabolites were determined by gas chromatography coupled to mass spectrometry. The mean levels of I-PCBs ranged between 6.78 ng/g ww and 16.33 ng/g ww (garfish and bluefish respectively). The sum of I-PCBs in all seafood studied did not exceed the EU maximum level. Hydrophilic marine biotoxins determination was performed by HPLC with postchromatographic oxidation. Lipophilic marine toxins were determined on liquid chromatograph coupled to mass spectrometry. The analyzed marine biotoxins were under the limit of detection.
