AB  - Understanding the mechanisms through which persistent organic pollutants (POPs) 
      form during combustion processes is critical for controlling emissions of POPs, 
      but the mechanisms through which most POPs form are poorly understood. 
      Polyhalogenated dibenzo-p-dioxins and dibenzofurans (PXDD/Fs) are typical toxic 
      POPs, and the formation mechanisms of PXDD/Fs are better understood than the 
      mechanisms through which other POPs form. In this study, a framework for 
      identifying detailed PXDD/Fs formation mechanisms was developed and reviewed. The 
      latest laboratory studies in which organic free radical intermediates of PXDD/Fs 
      have been detected in situ and isotope labeling methods have been used to trace 
      transformation pathways were reviewed. These studies provided direct evidence for 
      PXDD/Fs formation pathways. Quantum chemical calculations were performed to 
      determine the rationality of proposed PXDD/Fs formation pathways involving 
      different elementary reactions. Many field studies have been performed, and the 
      PXDD/Fs congener patterns found were compared with PXDD/Fs congener patterns 
      obtained in laboratory simulation studies and theoretical studies to mutually 
      verify the dominant PXDD/Fs formation mechanisms. The integrated method involving 
      laboratory simulation studies, theoretical calculations, and field studies 
      described and reviewed here can be used to clarify the mechanisms involved in 
      PXDD/Fs formation. This review brings together information about PXDD/Fs 
      formation mechanisms and provides a methodological framework for investigating 
      PXDD/Fs and other POPs formation mechanisms during combustion processes, which 
      will help in the development of strategies for controlling POPs emissions.
