Abstract

Lead poisoning was diagnosed in four spectacled eiders (Somateria fischeri) and one common eider (Somateria mollissima) found dead or moribund at the Yukon Delta National Wildlife Refuge, Alaska (USA) in 1992, 1993, and 1994. Ingested lead shot was found in the lower esophagus of one spectacled eider and in the gizzard of the common eider. Lead concentrations in the livers of the spectacled eiders were 26 to 38 ppm wet weight, and 52 ppm wet weight in the liver of the common eider. A blood sample collected from one of the spectacled eiders before it was euthanized had a lead concentration of 8.5 ppm wet weight. This is the first known report of lead poisoning in the spectacled eider, recently listed as a threatened species by the U.S. Fish and Wildlife Service.

摘要

1992年、1993年和1994年，在美国阿拉斯加育空河三角洲国家野生动物保护区发现4只王绒鸭（Somateria fischeri）和1只普通绒鸭（Somateria mollissima）死亡或濒死，经诊断为铅中毒。在1只王绒鸭的下食道和普通绒鸭的砂囊中发现了摄入的铅弹。王绒鸭肝脏中的铅浓度为湿重26至38 ppm，普通绒鸭肝脏中的铅浓度为湿重52 ppm。在1只王绒鸭安乐死之前采集的一份血样中，铅浓度为湿重8.5 ppm。这是王绒鸭铅中毒的首次已知报告，王绒鸭最近被美国鱼类和野生动物管理局列为受威胁物种。
