Levels of brominated flame retardants in Northern Fulmar (Fulmarus glacialis) eggs from the Faroe Islands.
Eggs from Northern Fulmars (Fulmarus glacialis) were sampled in the Faroe Islands. The content of the brominated flame retardants tri- to decabromodiphenyl ethers (BDEs) and 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE) were determined in nine samples in concentrations ranging from non-detectable to 7 ng g-1(l.w.). The BDE levels were similar as in an earlier study of BDE levels in the fulmar eggs from the Faroe Islands but 10-1000 times lower compared to studies of eggs from seabirds and birds of prey from Europe. The two hexaBDEs #153 and #154 were the most abundant congeners, which represented around 50% of the total mean BDE concentration. The levels of BDE #209 were below the limit of detection (1.24 ng g-1 l.w.) except for one sample, which showed a concentration of 7.18 ng g-1 l.w. BTBPE was detected in eight samples and the mean level was 0.11 ng g-1 l.w. This concentration was 150 times lower than the average total BDE concentration (including BDEs #28, #47, #100, #99, #154, #153, #183, #209). BTBPE has only been detected once before in biota. Also other bromo-containing compounds were detected in the fulmar eggs. One group identified was the polybrominated biphenyls (PBBs), but because of the absence of reference standards in the lab, these could not be quantified.
