Abstract

Vanadium in four species of pinnipeds (northern fur seals [Callorhinus ursinus], Steller sea lions [Eumetopias jubatus], harbor seals [Phoca vitulina], and ribbon seals [Phoca fasciata]) caught in the Northern Pacific was analyzed using ICP-MS to understand its accumulation and distribution. In northern fur seals, relatively high concentrations of vanadium were observed in the liver, hair, and bone. Ninety percent of the vanadium burden in the body was concentrated in these three tissues, which comprise <20% of total body weight. Hepatic vanadium concentrations in the four pinniped species were significantly correlated to age, although the levels varied with species. An increase in vanadium accumulation in the liver of northern fur seals was caused by an increase of retention in nuclei and mitochondria fraction in the cells. Vanadium concentrations in liver were significantly correlated with mercury, silver, and selenium concentrations in northern fur seals, Steller sea lions, and harbor seals.

摘要

利用电感耦合等离子体质谱法（ICP-MS）分析了在北太平洋捕获的四种鳍足类动物（北海狗[Callorhinus ursinus]、北海狮[Eumetopias jubatus]、港海豹[Phoca vitulina]和带纹海豹[Phoca fasciata]）体内的钒，以了解其积累和分布情况。在北海狗中，肝脏、毛发和骨骼中观察到相对较高浓度的钒。体内90%的钒负荷集中在这三个组织中，而这三个组织仅占总体重的不到20%。尽管不同物种的钒含量水平有所不同，但四种鳍足类动物肝脏中的钒浓度与年龄显著相关。北海狗肝脏中钒积累的增加是由于细胞内核和线粒体部分的保留增加所致。在北海狗、北海狮和港海豹中，肝脏中的钒浓度与汞、银和硒的浓度显著相关。
