Abstract:Polyurethane foam (PUF) passive air sampling was conducted in Haidian, Chaoyang, Fengtai, Shijingshan, Changping, Daxing, and Tongzhou District of Beijing between November 2010 and February 2011. The air concentrations of 13 polybrominated diphenyl ether (PBDE) congeners were analyzed with high resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS). The air concentrations of PBDEs (Σ13PBDEs) ranged from 0.97 to 41.1 pg/m3 (average 7.85pg/m3). Investigation of the distribution characteristics showed that the concentrations of PBDEs in the southeast region were significantly higher than those in northwest region, and the PBDEs levels in industrial areas and business districts were higher than those in suburbs and background areas.
