Halogenated Flame Retardants In Peregrine Falcon Eggs From Greenland:Concentration Development Over The Last 30 Years
Regulated and unregulated halogenated flame retardants in peregrine falcon eggs from Greenland
Median levels of regulated flame
retardants, i.e., polybrominated
diphenyl ethers (PBDEs), brominated biphenyl (BB)-153, and hexabromocyclododecane
(HBCD), in 33â48 eggs of peregrine falcons (<i>Falco peregrinus</i>) from Greenland were 1909, 359, and 5.98 ng/g lipid weight (lw),
respectively, and generally intermediate to levels in North America
and Europe. Unregulated flame retardants had lower median concentrations
of 1.06 (2-ethylhexyl-2,3,4,5-tetrabromobenzoate, EH-TBB), 2.42 (1,2-bisÂ(2,4,6-tribromophenoxy)-ethane,
BTBPE), 0.52 (2,4,6-tribromophenyl 2,3-dibromopropyl ether, DPTE),
and 4.78 (dechlorane plus) ng/g lw. Although these compounds are often
described as recent replacements for PBDEs, they were also present
in eggs from the 1980s. BDE-209 was the only compound with a significant
increase (+7.2% annual change) between 1986 and 2014, while BB-153
and DPTE decreased significantly (â8.0% and â2.8% annual
change, respectively). Dechlorane plus showed a nonsignificant increase.
Individual birds, equipped with light-logging geolocators, confirmed
the contaminant exposure over a large geographical area as the birds
spent nearly equal time periods in their breeding and wintering grounds
in Greenland and Central/South America, respectively, interrupted
by 5â6 weeks of migration through North America
