Abstract [en]

Forty-four unhatched eggs from white-tailed sea eagle (Haliaeetus albicilla), collected in four regions inSweden in 1992–2005, were analysed for contents of polybrominated diphenyl ethers (PBDEs),polybrominated biphenyl (PBB), hexabromocyclododecane (HBCD) and naturally occurring methoxylatedpolybrominated diphenyl ethers (MeO-PBDEs). Two freshwater areas—Lapland in the arctic zone (LAP) andinland lakes in central and southern Sweden (INL), and two brackish marine areas in the Baltic Sea—thesouth Bothnian Sea (SB) and the Baltic Proper (BP)—were chosen for comparison of the concentrations andcongener distributions in white-tailed sea eagles with different diet and migratory patterns. The geometricmean (GM) concentrations (ng/g lipid weight (l.w.)) of ∑5PBDE (BDE-47, -99, -100, -153, and -154) were720 (LAP), 1500 (INL), 4 100 (SB) and 4 300 (BP), whereas BDE-209 was not detectable in any of the samples.The GM concentrations for HBCD content in LAP, INL, SB and BP were 60, 90, 150 and 140 ng/g l.w.,respectively, whereas the corresponding values for BB-153 were 20, 30, 100 and 120 ng/g l.w. In general, theeggs from all four regions demonstrated similar patterns of PBDE congeners, with concentrations indescending order of BDE-47, -100, -99, -153 and -154. The ∑3-MeO-BDEs (6-MeO-BDE47, 2′-MeO-BDE68,5-Cl-6-MeO-BDE47) for these same regions (as above) were 80, 40, 340 and 240 ng/g l.w., respectively.∑3-MeO-BDEs for LAP and INL (freshwaters) were significantly different, whereas those for SB and BP were not.The presence of MeO-PBDEs in all of the inland samples indicates that there is an as-yet-unidentified sourceof these compounds in the freshwater ecosystem. Between the two more contaminated subpopulationsfrom the Baltic Sea coast, SB showed significantly lower productivity than BP, but no correlation was foundbetween productivity and PBDE, PBB and HBCD at the concentrations found in this study.
