Lead poisoning, associated with ingestion of spent lead shot, was diagnosed in an adult female Pacific loon (Gavia pacifica) observed with partial paralysis on 13 June 2002 and found dead on 16 June 2002 on Kigigak Island, Yukon Delta National Wildlife Refuge, western Alaska, USA. A necropsy revealed three pellets of ingested lead shot in the loon's gizzard and a lead liver concentration of 31 ppm wet weight, which was consistent with metallic lead poisoning. This is the first report of lead poisoning in a Pacific loon and is the only account of lead toxicosis associated with ingestion of lead shot in any loon species breeding in Alaska.
2002年6月13日，在美国阿拉斯加西部育空河三角洲国家野生动物保护区的基吉加克岛，一只成年雌性太平洋潜鸟（Gavia pacifica）被观察到部分瘫痪，于2002年6月16日死亡，诊断为与摄入用过的铅弹有关的铅中毒。尸检发现潜鸟砂囊中含有三颗摄入的铅弹，肝脏铅浓度为湿重31 ppm，这与金属铅中毒相符。这是太平洋潜鸟铅中毒的首例报告，也是阿拉斯加任何潜鸟物种中唯一一例与摄入铅弹有关的铅中毒病例。
