Flame retardants and organochlorine pollutants in bald eagle plasma from the Great Lakes region.
We report measurements of polybrominated diphenyl ethers and of emerging flame retardants in the plasma of nestling bald eagles sampled from early May to late June of 2005. Concentrations of total PBDEs ranged from 0.35 ng g(-1) ww to 29.3 ng g(-1) ww (average=5.7+/-1.9 ng g(-1) ww). The most abundant congeners were BDE-47, BDE-99, and BDE-100. The fully brominated congener, BDE-209, was detect...

متن کاملRegulation of Bald Eagle Reproductive Rates in Southeast Alaska
I examined the influence of food abundance and habitat quality on reproduction of Bald Eagles (Haliaeetus leucocephalus) in the Chilkat Valley, Alaska. The proportion of active nests was greatest and the timing of laying earliest in portions of the study area where food was most abundant. Clutch size was not related to food availability. Offspring survival was higher in breeding areas where foo...
متن کاملMercury in bald eagle nestlings from South Carolina, USA.
Bald eagles (Haliaeetus leucocephalus) may be at risk from contaminants in their diet and young birds may be particularly sensitive to contaminant exposure. To evaluate potential risks from dietary mercury exposure to eagle nestlings in South Carolina (USA), we surveyed mercury concentrations in 34 nestlings over two breeding seasons (1998 and 1999). Samples were also obtained from several post...
