AB  - The impact of wastewater irrigation on the distribution of two groups of 
      persistent organic pollutants (POPs), polychlorinated biphenyls (PCBs) and 
      polybrominated diphenyl ethers (PBDEs), in farm soil was investigated in this 
      study. The concentrations of total analyzed PCBs were in the range 
      256-2140pgg(-1) on dry weight basis in surface soils. There was a higher 
      accumulation of PCBs in farms irrigated by wastewater, with decachlorobiphenyl 
      (CB-209) as the predominant congener. The spatial distributions of PBDEs were 
      similar although not as obvious as that of PCBs, and BDE-209 was the predominant 
      congener at 2040-496000pgg(-1)dw, accounting for >96% of the total analyzed 
      PBDEs. However, no significant correlations could be found between PCB and PBDE 
      concentrations in the topsoil samples, and also with soil organic content between 
      the different sites. On the other hand, soil vertical profiles showed significant 
      relationship with soil organic content in cores taken from farms irrigated with 
      wastewater. The vertical distribution was quite uniform at the topsoil, 
      corresponding to the plowed layer, and decreased thereafter exponentially. 
      Furthermore, the soil vertical distribution was found to be congener specific for 
      PCBs, where less chlorinated congeners were able to penetrate deeper into the 
      soil while heavier congeners were more restricted in their movement. This 
      fractionation process was however not found for PBDEs. Also, the prevalence and 
      high relative concentrations of CB-11 and CB-209 suggests that these PCB 
      congeners should more often be included in routine environmental analysis in 
      order to identifying unusual contamination sources.
