Estimation of level contamination of marine ecosystems with heavy metals is important task in the field of MSFD. Total zooplankton samples were collected using a standard zooplankton net (mesh size=112 µm, mouth diameter=50 cm) from Sinop coast of the Black Sea, Turkey in 2011 and 2012. Concentrations of Al, As, Cu, Zn, Hg, Fe, Cd and Pb were determined in the total zooplankton samples. The average concentration of heavy metals followed order: Fe > Al >Zn > Pb > Cu > As > Cd > Hg. Estimated Hg was below the detection limit among all heavy metals in all samples. Fe was the most common heavy metal in total zooplankton samples present in all, Al was the other heavy metal commonly present in the samples. Pb showed high value (210 mg • kg-1) in total zooplankton. Similar to Pb, a high average concentration of As (40 mg • kg-1) was observed in total zooplankton. Cd was 1.1 mg • kg-1 .

“…Studies comparing the metal accumulation in muscle and liver of fish show lower metal concentration in the former. This trend has been recorded in marine fishes, in L. mahsena, in a previous study35,36,37 , in T. albacores, a study 38 , in S. putnamae, in a study and in Soleasolea, and Sparusaurata, by another researdhers 27 . Cd and Pb, have no biological role and hence they are harmful to living organisms even at considerably low concentrations.…”

Objectives: The fish samples were collected from the three different cities of Yemeni coasts. Aden, Al-Hodeidah and AL-Mukalla were chosen for the sample collection. Lethrinusmahsena, Thunnustonggol, Sphyraenajello and Epinephelusareolatus fish samples were considered for the study as they are more common eatable fish among the population. Methods: The study was carried out in the all three seasons of winter 2011, summer 2012 and winter 2013 in order to check seasonal variation of heavy metal pollution.Total Fish (108 samples of each muscles, liver and gills) were analyzed. The four heavy metals lead, Cadmium, Mercury and arsenic which are considered highly toxic were detected in the samples in the year 2010, 2012 and 2013. Results: The mean concentration of Pb, Cd, Hg and as in muscle was 0.101±0.012, 0.046±0.010, 0.058±0.002 and 0.089±0.002µg.g-1 dry wt. respectively; whereas in liver was 0.196±0.033, 0.132±0.020, 0.102±0.007 and 0.115±0.0005µg.g-1 dry wt. respectively; whereas in gill was 0.294±0.042, 0.196±0.063, 0.016±0.0006 and 0.034±0.0005µg.g-1 dry wt. respectively. The results showed that, the heavy metals concentrations were high in stations AL-Hudaydah and AL-Mukalla and low in station of Aden. Also the heavy metals concentrations were high in Seasons summer and low in Seasons winter. Conclusion: From the heavy metal concentrations mentioned above we can see that somewhere the concentration is crossing the limits as permissible by the World Health Organization. It suggests a high risk to the health of human being on the consumption of contaminated fish. Therefore it is recommended that the practice of trace element detection should be continued in order to update whether the heavy metal concentration is above or below the permissible limits and if it is above the limit then precautions must be taken to avoid possible consumption of contaminated eatables.

“…These values were much higher than those presented in this study but were safe to be consumed ( Table 1 ) [ 54 ]. Seabream from the Sinop Coast of the Black Sea (Turkey) also had higher contents of Zn (10.72–22.34 mg/kg) and Cu (3.48–5.21 mg/kg), but these values were within the limits set by the Commission Regulation and Turkish Food Codex [ 55 ]. The muscles of flounder from the Baltic Sea (Poland) contained Zn and Cu values as follows: 14–27 mg/kg dry weight and 0.3–1.1 dry weight [ 56 ].…”

The aim of this study was to estimate the fish quality in terms of the Cu, Fe, Mn and Zn contents. The research material was the muscle tissue of the fish crucian carp (Carassius carassius Linnaeus, 1758), flounder (Platichthys flesus Linnaeus, 1758), Gilthead seabream (Sparus aurata Linnaeus, 1758), mackerel (Scomber scombrus Linnaeus, 1758), Blue grenadier (Macruronus novaezelandiae Hector, 1871), rainbow trout (Oncorhynchus mykiss Walbaum, 1792), tench (Tinca tinca Linnaeus, 1758), tilapia (Oreochromis niloticus Linnaeus, 1758), Walleye pollock (Gadus chalcogrammus Pallas, 1814) and perch (Perca fluviatilis Linnaeus, 1758.). Heavy metals were determined with the atomic absorption spectrometry method (AAS). Significantly high concentrations of zinc (19.52 mg/kg wet weight), copper (0.77 mg/kg) and iron (6.95 mg/kg) were found in the muscles of crucian carp (p < 0.05) compared to the other fish studied, whereas Walleye pollock had a higher content of manganese (0.266 mg/kg) (p < 0.05). All studied fish species do not pose a threat to humans from these four metals. This was indicated by quality indexes (THQ and HI) whose values were below one. The values of these metals also did not exceed the maximum allowable concentrations established by the FAO (1983), but monitoring both the aquatic environment and the fish living there is necessary, for example, for the time-changing abiotic and biotic factors that can cause an increase in metals in the organs of fish.
