“…Concerning environmental dangers, one aspect is of most interest, namely the so‐called chondrichthyan bioaccumulation paradigm. In this context, first findings from S. canicula , in particular, have demonstrated intense heavy metal accumulation in the dogfish skin (Jeffree & Teyssie, 2006, Jeffree et al, 2006; Lozano et al, 2009). The high mercury concentrations in elasmobranchs increase with animal size from embryos to larger sharks (Pethybridge et al , 2010).…”

In contrast to the bony fishes, particularly the teleosts, the integument of elasmobranchs is rather unknown. Therefore, a description of the basic structural and functional features of shark and ray skin is given, based on a review of the literature and published or unpublished findings of the authors. The latter aspect makes it possible to document in more detail the specific structure of the skin layers regarding, particularly, the epidermis and its cell spectrum, the more or less robust dermis with its specific features, the very special scales with their derivates and the sophisticated sensoric integumental equipment. As far as possible, all important structures are discussed including their typical biological functions and results from applied scientific work. To some extent the information given is evaluated as compared with the much broader knowledge from the Osteichthyes.

“…The very few available data on Cd concentration in fish suggest higher Cd levels in liver in the Mauritanian region compared to the Moroccan coast and the Canary Islands (El Morhit et al, 2013;Lozano et al, 2009;Romeo et al, 1999;Sidoumou et al, 2005). Similarly, Cd levels are higher in the Canary Islands than in the Azores Islands (Lozano et al, 2009). Model results of Cd-bioaccumulation due to natural upwelling (Fig.…”

“…Low Cd levels observed in fish collected by commercial fisheries in the North-East Canary Islands (La Graciosa, Lanzarote, Lozano et al, 2009) suggest a weak influence of anthropogenic sources. This could be explained by a strong seasonality of the anthropogenic signature (see Fig.…”

“…For fish captured around the Canary Islands, off Morocco (Laâyoune) and Mauritania (Nouakchott), Cd levels are lower in muscles than in internal organs particularly liver, kidneys and spleen (El Morhit et al, 2013;Lozano et al, 2009;Romeo et al, 1999;Sidoumou et al, 2005). Metal levels in muscles reflect metal contents in the surrounding water, whereas levels in internal organs represent life-integrated metal storage (Tepe et al, 2008).…”

“…Thus, respectively low/high Cd levels in muscle tissue/internal organs suggest that fish mainly lives in Cd-depleted surface waters (Yeats et al, 1995) where plankton biomass is rich in Cd. The very few available data on Cd concentration in fish suggest higher Cd levels in liver in the Mauritanian region compared to the Moroccan coast and the Canary Islands (El Morhit et al, 2013;Lozano et al, 2009;Romeo et al, 1999;Sidoumou et al, 2005). Similarly, Cd levels are higher in the Canary Islands than in the Azores Islands (Lozano et al, 2009).…”

Comparative study of potential transfer of natural and anthropogenic cadmium to plankton communities in the North-West African upwelling

A Lagrangian approach based on a physical-biogeochemical modeling was used to compare the potential transfer of cadmium (Cd) from natural and anthropogenic sources to plankton communities (Cd-uptake) in the North-West African upwelling. In this region, coastal upwelling was estimated to be the main natural source of Cd while the most significant anthropogenic source for marine ecosystem is provided by phosphate industry. In our model experiment, Cd-uptake (natural or anthropogenic) in the North-West African upwelling is the result of an interplay between the Cd dispersion (by advection processes) and the simulated biological productivity. In the Moroccan waters, advection processes limit the residence time of water masses resulting in a low natural Cd-uptake by plankton communities while anthropogenic Cd-uptake is high. As expected, the situation is reversed in the Senegalo-Mauritanian upwelling where natural Cd-uptake is higher than anthropogenic Cd-uptake. Based upon an estimate of Cd sources, our modeling study shows, unexpectedly, that the anthropogenic signal of potential Cd-bioaccumulation in the Moroccan upwelling is of the same order of magnitude as the natural signal mainly present in the Senegalo-Mauritanian upwelling region. A comparison with observed Cd levels in mollusk and fishes, which shows overall agreement with our simulations, is confirming our estimates.

This paper investigated metal contamination in muscle tissue of the grouper (Epinephelus coioides) in the vicinity of a single buoy mooring (SBM3) at the Sultanate of Oman. The fish samples were analyzed for cadmium (Cd), copper (Cu), lead (Pb) and vanadium (V). The mean concentrations of Cd, Cu, Pb and V in the fish samples were 0.05 ± 0.004, 0.34 ± 0.013, 0.20 ± 0.018 and 0.03 ± 0.006 mg/kg, respectively. The results were compared with the corresponding permissible concentration limits according to the Sultanate of Oman (0.05, 3.28, 0.3 and 1.4 mg/kg for Cd, Cu, Pb and V, respectively) and the European Commission (0.05 mg/kg for Cd and 0.3 mg/kg for Pb). It was found that none of the overall mean metal concentrations exceeded the corresponding Omani legislation or European Commission limits. However, the overall mean concentration of Cd was identical to the maximum permissible limit of 0.05 mg/kg that has been established by both Commissions, and the limits were exceeded for mean Cd levels in fish at two of the six sampling stations at SBM3. In general, this study indicated that the fishes at SBM3 were not highly contaminated with these metals.
