Body distribution and growth- and nutritional status-dependent accumulation of 21 trace elements were investigated in harbor seals (Phoca vitulina) stranded in the North Sea coast in 2002. Higher concentrations and burdens of Mn, Se, Mo, Ag, Sn, Hg, and Bi in the liver, Cd in the kidney, As in the blubber, and Co, Sr, and Ba in the bone were observed. Significant positive correlations of hepatic Se, Mo, Ag, Cd, Sn, Hg, Tl, and Bi with standard body length were found, while significant negative relationships were detected for Mn, As, Rb, Sr, and Sb in the liver. Concentrations of Co, Se, Sr, Sn, Hg, and Bi in the liver, V, Sr, Ag, Sn, and Hg in the kidney, V, Mn, Co, Rb, Sr, Sn, Ba, and Pb in the blubber increased with decreasing blubber thickness of harbor seals, indicating enrichment of these elements in the target tissue by emaciation.
2002 年，对在北海沿岸搁浅的港海豹（Phoca vitulina）进行了研究，以调查 21 种微量元素在体内的分布、生长和营养状态依赖性积累情况。研究发现，港海豹肝脏中 Mn、Se、Mo、Ag、Sn、Hg 和 Bi 的浓度和负荷较高，肾脏中 Cd 的浓度较高，鲸脂中 As 的浓度较高，骨骼中 Co、Sr 和 Ba 的浓度较高。研究还发现，肝脏中 Se、Mo、Ag、Cd、Sn、Hg、Tl 和 Bi 与标准体长呈显著正相关，而 Mn、As、Rb、Sr 和 Sb 与肝脏中的含量呈显著负相关。此外，肝脏中 Co、Se、Sr、Sn、Hg 和 Bi 的浓度，肾脏中 V、Sr、Ag、Sn 和 Hg 的浓度，鲸脂中 V、Mn、Co、Rb、Sr、Sn、Ba 和 Pb 的浓度随着港海豹鲸脂厚度的减少而增加，这表明这些元素通过消瘦而在目标组织中富集。
