英文摘要: Air samples were collected from six locations during the periods of February, 2011-March, 2012 in Beijing city. PBDD/Fs were analyzed using HRGC-HRMS. The concentrations, congener profiles, spatial distribution, seasonal variation, and inhalation risk assessment were investigated. The mass concentrations of 2,3,7,8-substituted PBDD/Fs is 818-5748fgm-3 with an average of 2490fgm-3. The highest concentration was observed at site XS in February, 2011 and the lowest was at site BS in July 2011. The TEQ concentrations of PBDD/Fs ranged from 73.3 to 640fgI-TEQm-3, with an average of 190fgI-TEQm-3. The dominant contributor to total I-TEQ value is 2,3,4,7,8-PeBDF, with an average contribution of 35%. The PBDD/Fs at six sampling sites did not show obvious spatial variation. The concentration exhibits obvious seasonal variation, so atmospheric PBDD/F concentrations at six sample sites were much higher in winter than in summer. Residents in Beijing were exposed to PBDD/Fs with the daily inhalation doses being 39-138fgI-TEQkg-1day-1 for adult and 69-245fgTEQkg-1day-1 for children in winter, but in summer, the values were 10-33 for adult and 18-59 for children. The rough inhalation risk evaluation showed that the residents in Beijing had relatively higher exposure levels of PBDD/Fs in winter, so more research about PBDD/Fs should be carried out at once. © 2014 Elsevier Ltd.
