ÃÂ. ÃÂ. Zhmud, ÃÂ. I. Koshelev
The occurrence of lead shot in waterfowl gizzards, surveyed in 1969-1985 years was considered in the south of Western Siberia and in the southern Ukraine. The gastric contents were investigated of 1722 birds of 13 species. For Mallard, Garganey, Eurasian Teal, and Common Pochard the lead shot was detected in the coastal areas of the Danube Delta. Maximum infestation was registered for Garganey (33,3%) and Common Pochard (25,0%). The results are compared with data for other European countries. The necessity and effectiveness of interventions aimed at reducing the extent of lead contamination of waterfowl was discussed.
