AB  - The exchange of persistent organic pollutants (POPs) between different 
      compartments of a typical mature boreal forest was investigated. The study 
      focused on fluxes of polychlorinated biphenyls (PCBs) between the atmosphere, 
      vegetation and soil, and within the soil to assess whether this type of forest 
      acts as a final sink or temporary repository for POPs. The study, at a Swedish 
      site, suggested total PCB air-to-forest floor fluxes of 1.4 microg m(-2) 
      year(-1). Much of this could be attributed to compounds bound to particles that 
      may originate from needle surfaces. Degradation half-lives in soil between 6.4 
      and 30 years for tetra- to hepta-PCBs were obtained using a mass balance 
      approach. This field data-based method derived degradation rates of POPs in 
      background soils, although it may have underestimated the persistence of the 
      heavy PCB congeners. Compounds reaching the forest soil appear to be stored 
      efficiently and degraded slowly. As a first approximation, applying the findings 
      from this study site to boreal forests on a global scale suggests that 2-21% 
      (depending on the congener) of the estimated global atmospheric emission deposits 
      to these ecosystems.
