Description
Summary:Blood levels of lead were not exceptionally high in bald eagles in the southern portion of the Canadian prairies. The prevalence of elevated exposure to lead was assessed in a migrant population of bald eagles ( Haliaeetus leucocephalus) at a waterfowl staging area in the southern portion of the Canadian prairies, from September to November, 1992–1995. Of 103 eagles, 8% exhibited blood lead (PbB) concentrations suggestive of elevated exposure to lead (⩾0.200 μg ml −1 wet wt.). PbB concentrations in eagles from the study area ranged from
