“…Krill supplements, however, have much higher Cu concentrations, between 41 and 97 mg/kg, with a mean of 63 ± 30 mg/kg (Table 3). Nevertheless, those results are not unusual since values of 32-65 mg/kg Cu in krill have been reported previously (Li et al 2005). Levels in seagrass and algae varied between 5.0 to 23.9 mg Cu/kg in samples from the Mediterranean (Campanella et al 2001) and from 0.5 to 8.9 in samples from edible marine algae (van Netten et al 2000).…”

We determined the concentrations of Cd, Co, Cr, Cu, Hg, Ni, Pb, and Zn in dietary supplements of marine origin. Four supplement categories were studied; algae, coral, krill, and shark cartilage. A direct mercury analyzer was used for Hg determinations while acid digestions and ICP-AES were used for Cr analysis and ICP-MS for the other trace metals. Algae are the supplements showing the highest concentrations of Pb, Cr, and Ni with respective means of 1.6 mg Pb/kg dry weight (d.w.), 3.2 Cr mg/kg d.w., and 8.0 mg Ni/kg d.w. Krill supplements have the highest levels of Cd, Cu, and Zn with 0.65 mg Cd/kg d.w., 63 mg Cu/kg d.w., and 50 mg Zn/kg d.w., respectively. Shark cartilage supplements show the highest levels of Hg and Co with mean concentrations of 160 μg Hg/kg d.w. and 73 ± 51 μg Co/kg d.w., respectively. No samples in our study exceeded the provisional tolerable daily intakes set by Health Canada, the joint committee of the World Health Organization/Food and Agricultural Organization, or the U.S. Environmental Protection Agency. Nevertheless, Ni and Pb in algae and Hg in shark cartilage may end up contributing to a very significant portion of the allowable daily intake-leaving little room for normal intake through food consumption and other exposure pathways.

Le krill antarctique représente une très importante biomasse, peu contaminée par les polluants organiques ou les métaux lourds, pêchée depuis 1975 pour l'alimentation animale et l'aquaculture. Une valorisation plus intéressante pour la santé humaine est possible (enzymes, extraits actifs, huile de krill). Le krill contient peu de lipides, riches en EPA et DHA très biodisponibles car présents pour une part importante dans des phospholipides. Un faisceau convergent d'éléments montre l'intérêt potentiel de la consommation de krill dans le domaine cardiovasculaire ; les études dans les autres champs de la santé sont prometteuses mais beaucoup plus limitées. Bien qu'il n'y ait pas de raison de s'inquiéter sur la sécurité des produits issus du krill, les particularités de la réglementation européenne sur les nouveaux aliments et les allégations pourraient en freiner le développement commercial.Abstract: Antarctic krill represents a very large biomass, little contaminated by organic pollutants and heavy metals and harvested since 1975 for animal feed and aquaculture. Its expanded use in human health is possible through enzymes, various krill extracts and oils. The fat content of krill is low, but it is rich in EPA and DHA of high bioavailability given their presence in phospholipids. A number of overlapping characteristics demonstrate the potential krill consumption has in controlling cardiovascular disease; in other areas of health, there are promising, although few, studies. Whereas there are no safety concerns regarding krill products, specific European regulations on new food products and nutrition claims could limit their commercial development.

“…Either the offline or online combination of SE-HPLC and ICP-MS for determination of the cytosolic metal distribution in various aquatic invertebrates and vertebrates has been used by various authors (Mason and Storms, 1993;Ferarrello et al, 2002;Li et al, 2005;van Campenhout et al, 2008;Krasnići et al, 2012). In our knowledge cytosolic distribution of metals was not investigated with reference to seasonality.…”
