AB  - The long-range transport (LRT) of organic chemicals in the environment is 
      reviewed, with particular focus on the role of environmental fate and transport 
      models and the relationship between model results and field data. Results from 
      generic multimedia box models, spatially resolved multimedia box models, and 
      atmospheric transport models are highlighted, including conceptual investigations 
      of cold-trap effect and global fractionation as well as results for particular 
      chemicals, such as hexachlorocyclohexanes, DDT, polychlorinated biphenyls, 
      perfluoroocctanoic acid, and polybrominated diphenyl ethers. Comparison of model 
      results to field data shows that in many cases environmental fate models provide 
      a good description of the distribution dynamics observed in the field, with 
      deviations between measured and modeled concentrations around a factor of five. 
      Sorption to atmospheric aerosols as a key process influencing the LRT of 
      semivolatile organic chemicals (SOCs) is discussed, and the need for more 
      measurements of the aerosol-air partitioning of SOCs and of the reactivity of 
      particle-bound chemicals is pointed out. Key findings from field campaigns 
      measuring legacy persistent organic pollutants (POPs) as well as new POPs are 
      summarized. Finally, the relationship between science and politics in the field 
      of POPs is addressed. Research into the LRT of organic chemicals has always 
      occurred in interaction with political activities aiming to reduce the emissions 
      of POPs. Since the late 1990s, the Stockholm Convention and the Aarhus Protocol 
      on POPs have formed an important political context for research concerning POPs; 
      the implementation of these international treaties creates a demand for ongoing 
      research into the LRT of organic chemicals.
