TI  - Long-range transport and global fractionation of POPs: insights from multimedia 
      modeling studies.
PG  - 177-88
AB  - The long-range transport of persistent organic pollutants (POPs) is investigated 
      with two multimedia box models of the global system. ChemRange is a purely 
      evaluative, one-dimensional steady-state (level III) model; CliMoChem is a 
      two-dimensional model with different temperatures, land/water ratios and 
      vegetation types in different latitudinal zones. Model results are presented for 
      three case studies: (i) the effect of atmospheric aerosol particles on the 
      long-range transport of POPs, (ii) the effect of oceanic deposition on the 
      long-range transport of different PCB congeners, (iii) the global fractionation 
      of different PCB congeners. The model results for these case studies show: (i) 
      the low atmospheric half-lives estimated for several organochlorine pesticides 
      are likely to be inconsistent with the observed long-range transport of these 
      compounds; (ii) export to the deep sea reduces the potential for long-range 
      transport of highly hydrophobic compounds (but does not remove these chemicals 
      from the biosphere); (iii) there are different meanings of the term global 
      fractionation that refer to different aspects of the fractionation process and 
      need to be distinguished. The case-study results further indicate that the 
      influences of varying environmental conditions on the physicochemical properties 
      and the degradation rate constants of POPs need to be determined.
