TI  - Concentrations, gas-particle distributions, and source indicator analysis of 
      brominated flame retardants in air at Toolik Lake, Arctic Alaska.
PG  - 1274-1284
AB  - Brominated flame-retardants (BFRs) can be released from consumer products, 
      resulting in accumulation in the surrounding environment and/or long-range 
      transport to remote environments. We evaluated concentration changes in a suite 
      of BFRs, including 13 polybrominated diphenyl ethers (PBDEs) and 
      1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), in air at Toolik Lake, Arctic 
      Alaska during the Northern Hemisphere summer of 2013. A high-volume active air 
      sampler was used to collect 2 day integrated samples at the field station and 
      three flow-through air samplers were used to collect 18 day integrated samples 
      along a transect extending away from the field station. The BDE congeners 
      associated with the penta-BDE commercial mixture (BDE-47, -99, and -100) were the 
      most frequently detected BFRs and were found at concentrations consistent with 
      those reported at other Arctic sites. Gas-particle distributions were influenced 
      by temperature and correlations between gas-phase concentrations and temperature 
      suggested that either volatilization from local sources or re-emission from 
      secondary sources (that is, re-volatilization of BFRs that had migrated 
      northwards from distant sources) was important for the lower-brominated BFRs 
      during the warmer months. Source indicator analysis suggested no single dominant 
      geographic source of BFRs while results from the flow-through samplers indicated 
      that the field station itself was not a significant source of BFRs.
