Brominated Flame Retardants in Glaucous Gulls from the Norwegian Arctic: More Than Just an Issue of Polybrominated Diphenyl Ethers

摘要: Several, unregulated, current-use brominated flame retardants (BFRs), including hexabromobenzene (HBB), 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), pentabromoethylbenzene (PBEB), pentabromotoluene (PBT), and hexabromocyclododecane (as total-(α)-HBCD), were examined in egg yolk plasma of male female glaucous gulls (Larus hyperboreus) from the Norwegian Arctic. Also BDE209 38 tri- to nona-BDE congeners biphenyl (BB) 101. The HBB, BTBPE, PBEB, PBT had high detection frequencies variability samples, their concentrations ranged nondetectable (<0.02−0.27 ng/g wet wt) 2.64 wt. range non-BDE BFRs generally highest males relative females. Total-(α)-HBCD among non-PBDE (up 6.12 63.9 wt yolk, respectively). Next was HBB with within a comp...
