TI  - Field deployment of thin film passive air samplers for persistent organic 
      pollutants: a study in the urban atmospheric boundary layer.
PG  - 42-8
AB  - This paper reports on the first field deployment of rapidly equilibrating 
      thin-film passive air samplers under ambient conditions. The POlymer-coated Glass 
      (POG) samplers have a coating of ethylene vinyl acetate (EVA) less than 1 microm 
      thick applied to a glass surface. This can be dissolved off after exposure and 
      prepared for the quantification of persistent organic pollutants (POPs) that have 
      partitioned into the film during field exposure. In this study, POGs were 
      deployed at various heights on the CN Tower in Toronto, Canada, to investigate 
      the vertical distribution of selected compounds (PCBs, PAHs, organochlorine 
      pesticides) in the atmospheric boundary layer of an urban area. The feasibility 
      of the method to detect POPs from a few cubic meters of air was demonstrated, 
      indicating the potential for rapid, low-volume sampling of air for ambient levels 
      of POPs. PAH levels declined sharply with height, confirming ground-level 
      emissions in urban areas as sources of these compounds; PCBs did the same, 
      although less strongly. Different sampling events detected different vertical 
      distributions of OC pesticides which could be related to local or distantsources, 
      and variations in POPs on the samplers in these different events/heights 
      demonstrate the dynamic nature of sources and atmospheric mixing of POPs.
