Abstract

We investigated the occurrence, source and exposure time of lead poisoning in whooper swans (Cygnus cygnus cygnus) and Bewick's swans (Cygnus columbianus bewickii) in Japan during the winters of 1984-1987. Concentrations of lead in various tissues and physiological evidence of lead shot in some birds indicated that lead shotgun pellets were the source of lead, and exposure occurred after the birds arrived in Japan. Mortality probably occurred within 30 days after exposure to, and retention of, lead shot in the gizzard.

摘要

我们调查了1984年至1987年冬季期间日本大天鹅（Cygnus cygnus cygnus）和小天鹅（Cygnus columbianus bewickii）铅中毒的发生情况、来源及暴露时间。各种组织中的铅浓度以及部分鸟类体内铅弹的生理证据表明，铅弹是铅的来源，且鸟类抵达日本后才发生暴露。死亡可能发生在鸟类接触并在砂囊中留存铅弹后的30天内。
