TI  - Persistent organic pollutants in boreal and montane soil profiles: distribution, 
      evidence of processes and implications for global cycling.
PG  - 8374-80
AB  - The distribution of persistent organic pollutants (POPs) within background soil 
      profiles was investigated in boreal (Norway) and montane (Italy) areas. The 
      typical build-up of slowly mineralizing humus layers, containing high amounts of 
      soil organic matter (SOM) makes soils of such ecosystems an important global sink 
      for POPs released to the environment. The study focused on evidence and 
      implications of processes influencing the fate of POPs in soil. POP deposition, 
      interaction with SOM, volatilization, leaching, degradation, and bioturbation are 
      discussed. Results indicate that the less volatile POPs such as hexa- and higher 
      chlorinated biphenyls (CBs) or polybrominated diphenyl ethers are very stable in 
      soil profiles, undergoing little translocation or (re)transfer to other 
      environmental compartments. In contrast, more volatile compounds (e.g., tri- and 
      tetra-CBs) were found in soil layers below those formed from vegetation ever 
      directly exposed to airborne POPs. This suggests the occurrence of downward 
      transport and hence limited surface-air exchange of more volatile POPs as they 
      are removed from the top layers. Such soils may therefore be able to retain 
      higher amounts of these compounds than just addressed by the capacity of their 
      surface layers.
