AB  - Concentrations of persistent organic pollutants (POPs) were measured for an 
      entire year in the region of Tuscany, Italy. Passive air samplers consisting of 
      polyurethane foam (PUF) disks were deployed over four sampling periods of 3-5 
      months from April 2008 to July 2009 in urban (n = 6) and rural (n = 4) sites. The 
      aim of the study was to characterize the spatial and seasonal variations in 
      selected POPs. The POP concentrations (pg m(-3)) in the air were dominated by 
      dichlorodiphenyltrichloroethane and metabolites (DDTs) and polychlorinated 
      biphenyls ( summation operator(7)PCBs). DDTs, and  summation operator(7)PCBs showed a clear decreasing urban > rural 
      gradient. The concentrations of DDTs and PCBs were up to 10 and 6 times higher, 
      respectively, in urban sites than in rural sites.  summation operator(7)PCBs showed a significant 
      correlation with the urbanized areas located <5 km around the sampling sites. For 
      hexachlorocyclohexanes (HCHs), alpha-HCH concentrations were similar at both sampling 
      sites and were found to be quite uniform during the four sampling periods. 
      Seasonal fluctuations were observed for DDTs, and  summation operator(7)PCBs, with the highest 
      concentrations observed during period 4 (summer-spring); this is most likely due 
      to a temperature-driven re-emission from local sources. These findings were also 
      supported by an air back trajectory analysis in the study area. This study 
      contributes new information about POP levels in the Italian atmosphere and 
      demonstrates the feasibility of using PUF disks to simultaneously assess seasonal 
      concentrations at different sampling sites.
