RESUMEN

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.
