AB  - Isotopic dilution gas chromatography combined with high resolution mass 
      spectrometry (GC/HRMS) has overwhelming advantages with respect to the accuracy 
      of congener-specific ultratrace analysis of complex persistent organic pollutants 
      (POPs) in environmental matrices. However, an isotopic dilution GC/HRMS method 
      for analysis of chlorinated and brominated polycyclic aromatic hydrocarbons 
      (Cl-PAHs and Br-PAHs) using (13)C-labelled congeners as internal standards has 
      not been established. In this study, a method for identification and 
      quantification of 38 congeners of Cl-PAHs and Br-PAHs in atmosphere and stack gas 
      samples from waste incinerators was developed using the isotopic dilution GC/HRMS 
      technique. The instrumental detection limits of the GC/HRMS method ranged from 
      0.2pg to 1.8pg for Cl-PAH congeners, and 0.7pg to 2.7pg for Br-PAH congeners, 
      which were about three orders of magnitude lower than those of the GC/quadrupole 
      MS method. This new method developed was also the first to enable determination 
      of Cl-PAH and Br-PAH homologs comprising congeners with the same molecular 
      skeleton and chlorine or bromine substitution numbers. Among the detected 
      congeners, seven Cl-PAH congeners and thirteen Br-PAH congeners that were 
      abundant in the atmosphere and stack gases released from waste incinerators were 
      firstly detected in real samples and reported using the established isotopic 
      dilution GC/HRMS method. The developed isotopic dilution GC/HRMS is significant 
      and needed for better studying the environmental behavior and health risk of 
      Cl-PAHs and Br-PAHs.
