| 摘 要： | 2010年11月至2011年2月利用聚氨酯泡沫(PUF)大气被动采样技术采集了北京市海淀、朝阳、丰台、石景山、昌平、大兴、通州等区域的大气样品,采用高分辨气相色谱/高分辨质谱联用法(HRGC/HRMS)分析了其中13种多溴联苯醚(PBDEs)同族体的污染浓度和分布特征.结果表明,北京大气中PBDEs总含量(Σ13PBDEs)为0.97~41.1pg/m3,平均值为7.85pg/m3.在区域分布规律方面呈现东南地区的采样点污染物浓度明显高于西北地区,工业地区和人口密集的商业地区明显高于郊区和背景对照区的分布特征.

| 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. |
