Of the 13, current-use, non-polybrominated diphenyl ether(PBDE) flame retardants (FRs) monitored, hexabromobenzene (HBB), pentabromoethylbenzene (PBEB), pentabromotoluene (PBT), 1,2-bis(2,4,6-tribromophenoxy)ethane(BTBPE) and 
- and 
-isomers of hexabromocyclododecane(HBCD), and the syn- and anti-isomers of the chlorinatedDechlorane Plus (DP) were quantified in egg pools of herringgulls (Larus argentatus) collected in 2004 from six sitesin all five of the Laurentian Great Lakes of North America.-HBCD concentrations ranged from 2.1 to 20 ng/g (wetweight (ww)). Other "new" FR levels ranged from 0.004 to1.4 ng/g ww and were much lower than those of themajor BDE congeners that are in technical mixtures (namelyBDE-47, -99, -100), where 
3PBDE ranged from 186 to498 ng/g ww. Nineteen hepta-BDEs (hepta = 4.9-11 ng/gww), octa-BDEs (octa = 2.6-9.1 ng/g ww), and nona-BDEs (nona = 0.12-5.6 ng/g ww) were detectible at allsix colonies, while BDE-209 was low but quantifiable (<0.1-0.21 ng/g ww) at two colonies. -DP (syn- and anti-isomers) concentrations in eggs from all sites rangedfrom 1.5 to 4.5 ng/g ww. Our findings indicate that motherherring gulls are exposed to several, current-use flameretardants via their diet, and in ovo transfer occurred to theireggs. Given the aquatic diet of herring gull, this suggeststhat there are non-PBDE BFRs present in the gull-associated aquatic food web of the Great Lakes.
