Original Works


In whole krill, krill muscle tissue, krill products and in fillets of the antarctic fishNotothenia rossi marmorata, Dissostichus eleginoides, andNotothenia gibberifrons the levels of Cd, Pb, Cu, Ni, Hg and As have been determined. The methods applied were electrothermal AAS for Cd, Pb, Cu, and Ni, cold-vapour and hydride-generation AAS for Hg- and As, respectively, usually after HNO, pressure decomposition and for As followed by a HClO4/H2SO4 treatment. Quality control was performed by analysis of appropriate Standard Reference Materials and working standards and by intercomparison with differential pulse anodicstripping voltammetry (DPASV) for Pb and Cd. The mean values obtained related to fresh weight for krill muscle meat (46 ng Cd/g, ≦ 50 ng Pb/g, 380 ng Cu/g, 130 ng Ni/g, ≦ 20 ng Hg/g, and 340 ng As/g) and fillets of antarctic fish (≦ ng Cd/g, ≦ 100 ng/Pb/g, ≦ 200 ng Cu/g, ≦ 150 ng Ni/g, ≦ 50 ng Hg/g, and 300-1500 ng As/g) confirm the absence of toxic risks for human food according to the present knowledge. Due to the somewhat higher, but not excessive, trace metal contents of krill products, these should be more suitable as a protein rich animal feed.

Vergleichende Studien zum Spurenmetallgehalt in marinen Biota

II. Spurenmetalle in Krill, Krillprodukten und Fischen aus der antarktischen Scotia-See


In Rohkrill, Krillfleisch, Krillprodukten und in Filets der antarktischen FischeNotothenia Rossi Marmorata, Dissostichus Eleginoides undNotothenia Gibberifrons wurden die Gehalte an Cd, Pb, Cu, Ni, Hg und As bestimmt. Als Methoden wurden elektrothermale AAS für, Pb, Cu und Ni, Kaltdampf-bzw. Hydridtechniken für Hg und As nach HNO3-Druckaufschluß, für gefolgt von einer Naßveraschung mit HCIO4/H2SO4, eingesetzt. Die Qualitätskontrolle erfolgte durch die gleichzeitige Analyse geeigneter Standardreferenzmaterialien und Arbeitsstandards sowie durch Vergleich mit der differentiellen Pulsinversvoltammetrie (DPASV) füb und Cd. Die erhaltenen, auf Frischgewicht bezogenen, Mittelwerte für Krillfleisch (46 ng Cd/g; ≦ 50 ng Pb/g; 380 ng Cu/g; 130 ng Ni/g; ≦ 20 ng Hg/g und 340 ng As/g) und im Filet antarktischer Fische (≦ 3 ng Cd/g; ≦ 100 ng Pb/g; ≦ 200 ng Cu/g; ≦ 150 ng Ni/g; ≦ 50 ng Hg/g und 300-1500 ng As/g) bestätigen nach derzeitigem Kenntnisstand deren toxische Unbedenklichkeit für die menschliche Ernährung. Aufgrund höherer, aber nicht exzessiver Spurenmetallgehalte der Krillprodukte durften sich diese eher als proteinreiches Tierfutter eignen.
