AB  - This paper reports on a field calibration and ambient deployment study with 
      rapidly equilibrating thin-film passive air samplers. POlymer-coated Glass (POG) 
      samplers have a coating of ethylene vinyl acetate (EVA) less than 1 microm thick 
      coated on to glass, which can be dissolved off after exposure and prepared for 
      quantification of persistent organic pollutants (POPs) that have partitioned into 
      the film during field exposure. In this study, POGs were exposed for up to 18 d, 
      in a study to assess compound uptake rates and their time to approach 
      equilibrium. Results confirmed theoretical predictions, with time to equilibrium 
      varying between a few hours to ca. 20 d for PCB-18 and PCB-138, respectively. 
      Performance reference compounds and contaminated POGs were used to investigate 
      depuration kinetics, confirming that lighter congeners behave extremely 
      dynamically with substantial losses from the films over periods of a few hours. 
      Repeated deployments of the samplers for different3-d periods yielded detectable 
      levels of a range of PCB congeners, which had partitioned from as little as 
      approximately 2 to 10 m3 air. This highlights the potential utility of POGs for 
      extremely sensitive and dynamic passive air sampling in the future to help 
      improve understanding of sources, environmental fate, and behavior of POPs. 
      Recommendations are made for future improvements/refinements in POG sampling and 
      handling procedures.
