TI  - Levels and vertical distribution of PCBs in agricultural and natural soils from 
      Sweden.
PG  - 344-52
AB  - Soils represent an important reservoir for persistent organic pollutants (POPs) 
      in the terrestrial environment and thus the fate of contaminants deposited to the 
      surface soils is important to understand. Since only a limited number of studies 
      of the vertical distribution of POPs are available in the literature, the purpose 
      of this study was to collect and analyze PCB concentrations in different layers 
      of soil cores taken at agricultural and non-agricultural sites in Sweden. PCB 
      concentrations at the agricultural site were nearly uniform on a dry weight basis 
      throughout the depth considered (0-12 cm) while a distinct gradient with depth 
      was observed at the five non-agricultural sites. On an organic carbon normalized 
      basis, the concentration gradient was maintained at three of the non-agricultural 
      sites while a more uniform distribution was observed at the other two sites. A 
      statistically significant relationship between dry weight soil concentrations and 
      organic carbon content was determined for all PCB congeners in the surface layers 
      (0-1 cm) but not in the deeper layers (4-5 cm, 9-10 cm). These results were 
      interpreted in relation to vertical soil transport processes and then the 
      implications for environmental fate models including soil compartments were 
      discussed.
