The unique, closed ecosystem of the Black Sea is of significant global importance. The levels and health risk of some trace elements (As, Cd, Cr, Cu, Fe, Ni, Pb and Zn) in wild and farmed mussels (Mytilus galloprovincialis) collected from the Bulgarian part of the Black Sea were determined and using different approaches such as Estimated Daily Intake (EDI), Target Hazard Quotient (THQ), Hazard Index (HI), Target risk (TR), human health risk levels were assessed. The mean maximum concentrations of the elements Cd, Cr, Cu, Fe, Ni, Pb and Zn in all mussel samples were below the maximum permissible limits (MPLs) except that which exceeded the limit of 2.00 mg/kg ww. Eicosapentaenoic (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3) were the major polyunsaturated fatty acids. The fatty acids profile studied mussels showed that the farmed mussels had higher PUFA/SFA ratios, DHA and EPA+DHA content and lower SFA, AI and TI values. The target risk (TR) values for Pb, Cr, Ni and As were calculated, evaluated and showed acceptable or negligible levels. Target hazard quotients (THQs) and hazard index (HI) from elemental intake were below 1 indicated no hazard from consumption. The benefit–risk ratio indicated that wild and cultured M. galloprovincialis are safe for human consumption.

Significant Difference

The levels of Fe, Zn, Mn, Cu, Pb, Cd and Hg in the edible tissues of Mytilus galloprovincialis Lamarck, 1819 (Mediterranean mussel) picked up from the Black Sea coasts of Turkey have been determined by Inductively Coupled Plasma – Mass Spectrometer (ICP/MS) with a view to biomonitoring metal contamination in 2015. In this work, a statistically significant difference in the amounts of all studied heavy metals analyzed was noticed amidst sampling areas namely Igneada, Sinop, Samsun and Trabzon so that appraise welfare threat for mussel consumers, utilization M. galloprovincialis as biomonitors. The outcomes of this study were contrasted with the outlines stated by the Ministry of Agriculture, Fisheries and Food (MAFF), the Turkish Food Codex and Commission Regulation (EC) for the harmless consumption restrictions of Bivalves as seafood. Moreover, former works with mussels in the Black Sea countries were reviewed and a summary of heavy metal amounts in mussels from whole the Black Sea waters were presented. In general these available measurements clearly indicated a low level heavy metal in M. galloprovincialis in coastal waters of the Black Sea. In this study the concentrations (mg metal kg-1 wet wt.) of metals ranged from 18-35 for Fe, 8-27 for Zn, 2.8-4.5 for Mn, 0.5-1.8 for Cu, 0.06-0.31 for Pb, 0.04-0.10 for Cd and 0.03-0.07 for Hg. Considering human health with respect to the investigated heavy metals, the estimated daily intakes (EDIs) did not exceed the permissible intakes. No chronic systemic risk was found since total hazard index (0.521) were quite below critical value 1, and the carcinogenic risk for heavy metals did not exceed the tolerable values. Although there was no health risk to consumed mussels from the Black Sea riparian countries, the amount of mussels consumed is mainly unknown in countries; thus, consumption of about 1 serving of mussels from clean coastal waters per week is enough.

Mean Concentration

The present study was performed to assess Cd, Pb, and Hg contaminations and human health risk in the warty crab Eriphia verrucosa (Forskål, 1775) in Akliman shores of Sinop Peninsula of the Black Sea. Heavy metals analysis was performed by inductively coupled plasma mass spectrometry. Among studied toxic metals, Pb had the highest mean concentration in E. verrucosa. The highest mean concentration of Pb (0.2 mg per kg of wet weight) was observed in male samples of the warty crab. However, higher concentrations of Cd and Hg (0.11 and 0.019 mg per kg of wet weight, respectively) were observed in females of E. verrucosa. The mean Cd values found in the warty crabs were higher in May and June than those in July and August. On the other hand, Pb values were recorded in July and August. The mean Hg values were not different between months except July and August for male samples of E. verrucosa. Foraging seasons of these crabs are different, which can lead to differences in prey size and ultimately metals intake. However, the results show that a toxic heavy metal concentration in edible tissues of crab from the southern Black Sea was within the permissible limits given by national and international food codices. Target hazard quotient (THQ) for each metal and hazard index (HI) were calculated to evaluate non-carcinogenic human health risks. Estimated THQs of Cd, Pb, and Hg suggest that these metals in the warty crab do not pose any apparent threat to humans, when the HI value is below the value of 1. The result of the analysis has shown that the warty crab E. verrucosa can be used as bioindicator as it contains variable levels of the metals observed. Since consumption is the main source of heavy metal intake by humans, monitoring studies are needed to protect public health and take preventive measures.
