测定了格陵兰海海豹（Pagophilus groenlandicus）和冠海豹（Cystophora cristata）的肉、肝、肾中必需微量元素铁、铜、锌、硒和非必需元素砷、镉、总汞、铅的含量。个别海豹之间的传播是相当大的。然而，多元统计简化了数据的评价。肌肉组织比肾脏和肝脏含有更低水平的元素。肾脏和肝脏组织也不同，特别是肝脏中的铁含量较高，肾脏中的镉含量较高。在肝脏和肾脏组织中，物种差异都很明显，帽海豹的大多数元素含量较高，而竖琴海豹的这两种组织中的砷含量较高。在所有组织中，雄性帽海豹的汞和硒含量都高于雌性。海豹的肌肉组织有轻微的性别差异，而肝脏和肾脏组织没有观察到差异。幼海豹的组织中铜和锌的含量普遍低于成年海豹，但幼海豹肌肉和肝脏中的铜和锌含量和肌肉中的铁含量一样高。年龄与成年海豹组织中微量元素含量无相关性。
Concentrations of the essential trace elements, iron, copper, zinc and selenium and the non-essential elements arsenic, cadmium, total mercury and lead, were measured in the meat, liver and kidney of two species of seals, harp seal (Pagophilus groenlandicus) and hooded seal (Cystophora cristata) collected in the Greenland Sea. The spread among the individual seals was considerable. However, multivariate statistics simplified the evaluation of the data. The muscle tissue contained lower levels of the elements than kidney and liver. The kidney and liver tissue were also different, in particular with higher levels of iron in the liver and higher levels of cadmium in the kidney. Species differences were clear in both liver and kidney tissue, with higher levels of most of the elements in the hooded seals, while the harp seals had a higher burden of arsenic in the two tissues. Male hooded seals had higher levels of mercury and selenium than the females in all tissues. For harp seal there was a slight difference between the sexes in the muscle tissue, while no difference was observed in the liver and kidney tissues. The juvenile seals generally had lower levels of the elements in their tissues than the adults, although copper and zinc were higher in the muscles and livers of the juveniles as was iron in the muscles. No correlation between age and trace element levels in the tissues of the adult seals was observed.
