AB  - A field calibration study of low density polyethylene (LDPE) for measuring 
      atmospheric concentrations of persistent organic pollutants (POPs) was performed 
      in East Providence (RI), USA. LDPE samplers were collected after 3, 7, 10, 14, 17 
      and 21 days of exposure along with samples from a co-deployed high volume 
      sampler. Uptake kinetics of POPs by LDPEs were confirmed both by using an uptake 
      study over time and the inclusion of performance reference compounds (PRCs). 
      Results indicated that only POPs with log sampler-air partitioning coefficient 
      (KPE-A) </= 7.6 were approaching equilibrium by the end of the deployment period, 
      whereas all the other POPs were still in the linear uptake rate. Sampling rates 
      (1.0-80 m(3) per day) were higher for some POPs when compared to literature 
      values possibly due to the open sampler housing design used. Derived KPE-As for 
      the detected POPs in field calibration study were correlated against the 
      compounds' octanol-air partitioning coefficients (log KOA): [log KPE-A = 0.88 +/- 
      0.02 x log KOA + 0.40 +/- 0.21 (R(2) = 0.96; n = 59; SE = 0.23)], and their 
      subcooled liquid vapour pressures (log PL/Pa): [log KPE-A = -0.82 +/- 0.02 x log PL 
      + 6.22 +/- 0.05 (R(2) = 0.96; n = 59; SE = 0.22)] to predict values for all POPs. 
      PL was generally found to be a better predictor of KPE-A for all POPs.
