HEAVY METAL ACCUMULATION IN ANTARCTIC KRILL
Abstract: Seventy-six samples of the Antarctic krill were collected from the stomach contents of the southern minke whales hauled up on the Japanese factory ship during her cruises in 1984185 and 1985186, and were analyzed for Cu, Zn, Fe, Mn, Ni, Cd, Pb, Co, and Hg. The mean concentrations of metals...

| Summary: | Abstract: Seventy-six samples of the Antarctic krill were collected from the stomach contents of the southern minke whales hauled up on the Japanese factory ship during her cruises in 1984185 and 1985186, and were analyzed for Cu, Zn, Fe, Mn, Ni, Cd, Pb, Co, and Hg. The mean concentrations of metals in the Antarctic krill were Cu-12.7, Zn-9.6, Fe-3.6, Mn-0.71, Ni-0.45, Cd-0.43, Pb-0.04, Co-0.02, and Hg-0.008,ug/wet g. Although no significant difference in concentrations of the metals with size and location was found, metal concentrations varied seasonally: High concentrations of Fe, Mn, Zn, Pb, and Hg were observed during January-February, 1985186, and during January, 1984185. The concentrations of Cu, Cd, Ni, and Co were higher in January to mid-February, 1986, and during January, 1985, and thereafter their concentration levels except for Cu decreased. 1. |
