Spatiotemporal Trends of Anthropogenic and Naturally Occurring Polybrominated Diphenyl Ethers in Long-Term White-Tailed Eagle Feather Collections
Using archived feathers from Norwegian, Swedish, and Greenlandic white-tailed eagles (Haliaeetus albicilla), we investigated long-term (1866-2015) spatiotemporal trends of polybrominated diphenyl ethers (PBDEs) and their methoxylated analogues (MeO-PBDEs). Concentrations of BDE 47 (constituting 47-6...
