Determination of heavy metals in Antarctic krill (Euphausia superba)

Heavy metal iron (Fe) , zinc (Zn) , manganese (Mn) , cadmium (Gd) , chromium (Cr) , nickel (Ni) , copper (Cu) , mercury (Hg) , molybdenum (Mo) , arsenic (As, submetallic) in whole shrimp, shrimp paste, minced shrimp, shrimp meal and shrimp sauce of Antarctic Krill (Euphausia superba) derivatives were determined by microwave digestion-ICP-MS method. The result showed that these heavy metals were all detected in different derivatives, but their contents were below the level of national food heavy metal sanitation limits. Content of zinc and copper were at a reasonable level .Derivatives of Antarctic krill were safe in the aspect of heavy metal indicator. It had wide application prospects in the future.
