AB  - The collection of 2,3,7,8-substituted polychlorinated dibenzo-rho-dioxins and 
      dibenzo furans (PCDDs/Fs) and dioxin-like polychlorinated biphenyls (dl-PCBs) 
      using a polyurethane form (PUF)-disk passive air sampler (PAS) was investigated 
      in urban-residential and industrial areas. This was performed to assess the 
      feasibility of using this method as an alternative to an active air sampler 
      (AAS). The PUF-disk PAS was exposed to ambient air over a period of 37-370 and 
      57-173 days in urban and industrial areas, respectively, together with AASs. The 
      sum of total toxic equivalent quantity (TEQ) SigmaPCDDs/Fs and Sigmadl-PCB was typically 
      high in the industrial area, with values within the range 0.171-0.635 
      pg-TEQ/m(3), and 0.037-0.300 pg-TEQ/m(3) in the urban-residential area. To derive 
      the time-weighted average (TWA) concentration from the PAS data accurately, it 
      was estimated that the PAS deployed for less than 80 days was adequate to 
      maintain linear accumulation conditions. PCDDs/Fs are mainly particle bound and 
      showed low average uptake rates of 1.4m(3)d(-1), while dl-PCBs were slightly 
      higher with 2.0m(3)d(-1) because of its high vapor pressure. Most of the congener 
      concentrations measured using the PAS and AAS were within a factor of two, 
      indicating that PASs can be used to monitor spatial and temporal variations in 
      the concentrations of persistent organic pollutants (POPs) in the atmosphere.
