“…In conclusion, this study confirms the importance of biomonitoring on fish species for a toxicological evaluation of the marine environment (Lasheen et al 2012), seafood safety (Raissy and Ansari 2014) and risks estimation on fish consumption (Renieri et al 2014). The higher residual levels in demersal and pelagic species than benthic suggest a significant role of anthropic activities in heavy metals pollution of marine surrounding area.…”

Fish represents a nutrient-rich food but, at the same time, is one of the most important contributor to the dietary intake of heavy metals. The aim of this study was to assess residual levels of Pb, Cd and Hg in different species, caught from FAO zones 37 1.3 and 37 2.2, particularly small pelagic, benthic and demersal fishes. The results obtained showed the absence of toxic metal in fishes from FAO zone 37 1.3. Relating to FAO zone 37 2.2, instead, in all samples we observed the absence of Pb, small concentrations of Cd (0.081±0.022 mg/kg) and higher Hg residual levels (0.252±0.033 mg/kg). Particularly, the trend of Cd contamination was similar in all species whereas Hg showed high levels in demersal, intermediate in pelagic and low in benthic species. However, only Cd concentrations exceed the MRL in mackerel, mullet, sea-bream fishes, according to Regulation CE n. 629/2008 and n. 488/2014.

“…For example, Külcü et al [23] reported that the Pb, Cu, Zn, and Fe levels in muscle tissues of M. merluccius were higher than those found in our study for same species. Similarly, Renieri et al [24] pointed out that the Cd and Pb contents in muscle tissue of L. budegassa were also higher than those found in our study for same species. This is perhaps due to our sampling area being a less contaminated marine environment compared to water (sampling area) given in Table 3.…”

Heavy metals are of particular concern due to their toxicity and bioaccumulation ability in aquatic ecosystems and aquatic organisms. In general, they are not biodegradable and have long biological halflives. According to the World Health Organization (WHO), heavy metals must be controlled in food sources in order to assure public safety [1]. Heavy metals are taken up and accumulated by aquatic organisms both from the surrounding medium and via food sources (deep-sea carnivorous fish in particular accumulate metals in their muscles via the food chain). The extent of heavy metal accumulation is affected by external (dissolved metals, physicochemistry, dissolved oxygen, interactions between metals, sediment, food, seasonal effects, geographical differences) and internal (individual variability, body size and development stage, sex, breeding condition, brooding, moulting and growth, behaviour) factors [2,3].Many species of marine benthic fish are largely being used to assess the quality of aquatic environments because they could concentrate large amounts of some metals in different tissues such as muscle and gills [4,5]. The gills are considered the main site of entry for the dissolved metals. They are sensitive to any change of water components and serve as a good indicator of water quality since gill filaments and lamellae provide a very large surface area for direct and continuous contact with contaminants Pol. J. Environ. Stud. Vol. 24, No. 4 (2015), 1743-1748 AbstractIn the present study, the concentration of cadmium (Cd), lead (Pb), copper (Cu), zinc (Zn), and iron (Fe) in the gill and muscle tissues of four benthic fish species (Merluccius merluccius, Lophius budegassa, Helicolenus dactylopterus, and Chlorophthalmus agassizi) from the northeastern Mediterranean Sea in Turkey were investigated. From the obtained results, the heavy metal concentrations in muscle were lowest and highest in the gills for each species. Cd was not detected in any tissues of the species. The order of heavy metal concentrations were found as Zn>Fe>Cu>Pb=Cd in muscle tissue samples for four selected fish species (p<0.05). In the muscle tissue, the highest concentration of Zn (5.875 μg/g) was found in Lophius budegassa. The concentrations of heavy metals in gills of four selected fish species were Fe>Zn>Cu>Pb>Cd (p<0.05). In the gills, the highest concentration of Fe (73.730 μg/g) was also found in Lophius budegassa. The comparison of our results with previous studies showed that the metal levels of tissues are variable in organisms caught from the same area. In our study, the concentrations of Cd, Pb, Cu, Zn, and Fe in the muscle tissue are less than the permissible limits set for heavy metals by food regulations.

“…These accumulation relationships between TE could have negative correlations where metals compete, or positive correlations where TE accumulate together and influence one another (Renieri et al, 2014). For example, a significant positive correlation (p < 0.001) between Zn and Cu, Pb and Bi, Mo and Co or Fe and Cr concentration were found.…”
