TI  - Using passive air samplers to assess urban-rural trends for persistent organic 
      pollutants. 1. Polychlorinated biphenyls and organochlorine pesticides.
PG  - 4474-83
AB  - Passive air samplers were used to investigate urban-rural differences of 
      polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) over an 
      integrated time period. Samplers consisting of polyurethane foam (PUF) disks and 
      semi-permeable membrane devices (SPMDs) were housed in protective chambers and 
      deployed at six sites for a 4 month duration in the summer of 2000. The sampling 
      transect originated in downtown Toronto and extended approximately 75 km 
      northward into a rural region. Results for the two types of samplers agreed well 
      with one another. Higher blank levels were encountered for the SPMDs, especially 
      for the OCPs, whereas blanks were very low for the PUF disks. Passive 
      sampler-derived air concentrations were consistent with previous measurements of 
      PCBs and OCPs in the region. The largest urban-rural gradient was observed for 
      PCBs (approximately 5-10 times). Chlordanes also showed an urban-rural gradient, 
      possibly reflecting past usage of chlordane on residential lawns and emissions 
      from treated house foundations. Other OCPs exhibited a rural-urban gradient 
      (dieldrin, endosulfan 1, and DDT isomers), which was attributed either to 
      off-gassing from previously treated agricultural soils (dieldrin and DDTs) or to 
      continued usage in agriculture (endosulfan 1). The results of this study 
      demonstrated the feasibility of using such devices to determine air 
      concentrations of persistent organic pollutants (POPs) and to assess their 
      spatial distribution for time-integrated samples. Data such as this is essential 
      for: model validation and for process research and addressing international 
      monitoring strategies on POPs.
