HEAVY METAL DISTRIBUTION IN WEDDELL SEALS (LEPTONYCHOTES WEDDELLII) FROM THE ANTARCTIC DURING JARE-32 (14th Symposium on Polar Biology)

概要
- 論文の詳細を見る
Concentrations of heavy metals in five Weddell seals (Leptonychotes weddellii) captured in the Antarctic for 1990-91 winter during JARE-32 were determined. Fe and Cu concentrations in the liver of Weddell seals were remarkably higher than those of other marine mammals, while Cd levels in the livers were rather lower. Markedly high Fe concentrations in the liver of Weddell seals might be related to the excellent diving ability of this species. Relatively lower Cd concentration in the liver of these seals suggests less feeding on squids which contain high Cd levels compared to fish.
