Abstract

A method for the treatment of lead poisoning in mute swans (Cygnus olor) is described. Chelation therapy, using sodium calcium edetate, was successful in resolving the clinical signs of lead poisoning in 49% of cases. Individually ringed swans were monitored after their release to the wild, in order to assess the long-term benefits of treatment. Re-sighting and recovery data suggested that at least 22% of swans treated for lead poisoning survived the first 2 years. The results indicate that despite treatment, once a swan becomes lead poisoned its chances of survival are reduced by 59% compared with untreated swans living in flocks.

摘要

本文描述了一种治疗疣鼻天鹅（Cygnus olor）铅中毒的方法。使用依地酸钙钠进行螯合疗法，在49%的病例中成功消除了铅中毒的临床症状。对单独佩戴环志的天鹅放归野外后进行监测，以评估治疗的长期效果。重新观察和回收数据表明，至少22%接受铅中毒治疗的天鹅在头两年存活下来。结果表明，尽管进行了治疗，但与未中毒的群居天鹅相比，一旦天鹅铅中毒，其存活几率会降低59%。
