“…Our data are in agreement with those measured in specimens from Mediterranean: mercury concentrations in muscle and liver of specimens from Atlantic are lower (Law et al, 1991;Das et al, 2003a). André et al (1991), though, makes an exception. Their data are compatible with ours for the Atlantic specimens data.…”

“…As reported by other authors, mercury levels in dolphins from the Mediterranean are generally higher than those found in the same species from the Atlantic (André et al 1991). This has been explained by the existence of natural mercury sources in the Mediterranean Sea and mercury rich inputs via rivers flowing through the Mt.…”

“…Only nine out of the available 60 samples here compared have a length of about 210 cm and therefore we assume a direct proportionality between age and length of the analyzed specimens and basically exclude significant bias due to the growth curve plateau effect. The highest Hg concentrations lie in liver of specimens of S. coeruleoalba from the French coasts (André et al 1991) followed by specimens from the Ligurian Sea, Israeli coasts, Sicily channel and Adriatic Sea ( Figure 5). The same geographical pattern of Hg concentrations emerges from muscle data although differences among the sampling areas are more evident ( Figure 5).…”

“…Mercury concentration in livers and muscles of S. coeruleoalba from the French Mediterranean coasts (André et al 1991), Israeli coasts (Roditi-Elasar et al 2003), Ligurian sea (Capelli et al 2000), and Adriatic sea (Cardellicchio et al 2002) are here considered and compared with our dataset from the Sicily Channel (Table II; Figures 5, 6). Analytical methods used to determine Hg concentrations in dolphins tissues from the different considered researches are totally comparable.…”

Concentrations of Hg were determined in tissues (muscle, heart, kidney, lung and liver) of two cetacean species (Stenella coeruleoalba and Tursiops truncatus) stranded along the Italian coasts during the period 2000-2009 and compared with those previously reported by other authors from different areas of the Mediterranean basin. The highest concentrations of Hg were found in liver samples of both species (8.4-1752 mg·kg −1 dry weight for S. coeruleoalba and 9.6-1404 mg·kg −1 d.w. for T. truncatus). Statistically significant dissimilarities of Hg concentrations were recorded in muscle and liver tissues of S. coeruleoalba stranded in different geographical areas of the Mediterranean Sea as apparent direct response to uneven impacts of Hg pollution in the basin. A noteworthy outcome was that cetaceans stranded on the French coasts showed significantly higher levels of Hg contamination than those from other Mediterranean areas while the eastern part of the basin evidences the lowest Hg concentrations in the studied organisms. Moreover, the results of this study tentatively suggest the existence of different sub-populations of the two species in the basin.

“…Metal concentrations in pilot whales Globicephala melas Traill, 1809 caught in the drive fishery of the Faroe Islands in 1977 and 1978 (Julshamn et al 1987) were generally higher than those encountered in other species (Johansen e t al. 1980, Helle 1981, Falconer et al 1983, Wagemann et al 1983, Ronald et al 1984, Andre et al 1990a, b, 1991. A significant fraction (about 75 %) of the population of pilot whales sampled off the Faroe Islands had blood Cd concentrations higher than minimum adverse-effect levels established for humans (Caurant & Amiard-Triquet unpubl.).…”

Ecological and biological factors controlling the concentrations of trace elements (As, Cd, Cu, Hg, Se, Zn) in delphinids Globicephala melas from the North Atlantic Ocean 'CNRS URA 1356, Service d'Ecotoxicologie. Faculte de Pharmacie, 1 rue Gaston Veil, F-44035 Nantes Cedex, France 'CNRS-IFREMER, CREMA I'Houmeau B.P. 5, F-17137 l'Houmeau, France ABSTRACT: Trace elements (As. Cd, Cu, Hg, Se and Zn) were determined in liver and kidney of pilot whales Glob~cephala melas Traill, 1809 collected from 7 schools caught at different seasons around the Faroe Islands. These and other biological data at our dlsposal enabled us to confirm and to define more accurately the relations shown prev~ously between age, sex and trace element concentrations in marine mammals. The most striking features were: (1) the elevated levels of Cd and Hg in pilot whales compared to other marine mammals and to minimum adverse-effect levels established for humans; (2) the biocumulative behaviour of Cd and Hg; (3) the high correlations between Hg and Se, predominantly influenced by age; and (4) the high correlations between Cd and Zn, the levels of which appear to be mainly dependent on the school to which the specimens belong. This last may be tentatively attributed to the fact that the schools sampled correspond to different sub-populations with different genetic charactenstics. The apparent metal tolerance of pilot whales and the health consequences to consumers of flesh of marine mammals are discussed.
