Coupling passive air sampling with emission estimates and chemical fate modeling for persistent organic pollutants : a feasibility study in Northern Europe.
Passive air samplers (polyurethane foam disks) were deployed at 23 background locations along a broadly west−east transect in 8 northern European countries and analyzed for PCBs, PBDEs, PAHs, and a range of organochlorine pesticides (HCB, DDTs, and DDEs). PCBs and PAHs were highest at the center of...

Passive air samplers (polyurethane foam disks) were deployed at 23 background locations along a broadly west−east transect in 8 northern European countries and analyzed for PCBs, PBDEs, PAHs, and a range of organochlorine pesticides (HCB, DDTs, and DDEs).

HCB was relatively uniformly distributed, reflecting its persistence and high degree of mixing in air. Higher DDE and DDT levels occurred in Eastern Europe and at several sites in Central Europe.
