%X The occurrence, distribution, and temperature dependence
in the
marine atmosphere of several alternative brominated flame retardants
(BFRs), Dechlorane Plus (DP) and polybrominated diphenyl ethers (PBDEs)
were investigated during a sampling cruise from the East Indian Archipelago
toward the Indian Ocean and further to the Southern Ocean. Elevated
concentrations were observed over the East Indian Archipelago, especially
of the non-PBDE BFR hexabromobenzene (HBB) with concentrations up
to 26 pg m–3 which were found to be related to continental
air masses from the East Indian Archipelago. Other alternative BFRs
pentabromotoulene (PBT), pentabromobenzene (PBBz), and 2,3-dibromopropyl-2,4,6-tribromophenyl
ether (DPTE)were elevated, too, with concentrations up to
2.8, 4.3, and 2.3 pg m–3, respectively. DP was detected
from 0.26 to 11 pg m–3 and bis-(2-ethylhexyl)-tetrabromophthalate
(TBPH) ranged from not detected (nd) to 2.8 pg m–3, respectively. PBDEs ranged from nd to 6.6 pg m–3 (Σ10PBDEs) with the highest individual concentrations
for BDE-209. The approach of Clausius–Clapeyron (CC) plots
indicates that HBB is dominated by long-range atmospheric transport
at lower temperatures over the Indian and Southern Ocean, while volatilization
processes and additional atmospheric emissions dominate at higher
temperatures. In contrast, BDE-28 and -47 are dominated by long-range
transport without fresh emissions over the entire cruise transect
and temperature range, indicating limited fresh emissions of the meanwhile
classic PBDEs.
