南极磷虾中重金属含量的测定

采用微波消解-电感耦合等离子-质谱法（MD-ICP-MS）测定了南极磷虾整虾、虾膏、虾糜、虾粉、虾油中铁（Fe）、锌（Zn）、锰（Mn）、镉（Cd）、铬（Cr）、镍（Ni）、铜（Cu）、汞（Hg）、钼（Mo）、砷（As,类金属）的含量。结果表明,这10种重金属在南极磷虾各衍生产品中均被不同程度的检测出来,含量均在国家食品限量标准范围内,南极磷虾各衍生产品中锌铜含量处于合理的水平。在重金属指标这方面,南极磷虾各衍生产品均是安全的,具有广阔的应用前景。 

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.
