Book excerpt: Wing bones of 4,190 ducks of seven species collected in 1972 and 1973 were analyzed for lead to provide a base line for lead burdens and to determine geographic patterns of lead exposure in these species. Lead residues ranged from trace amounts to 361 ppm and reflected the history of exposure to lead from ingested shotshell pellets and other sources. Wing bones of adults contained higher residues than did those of immatures. Levels were lower in birds from the Central Flyway than in those from other flyways.
