High volume air samples were taken in Stockholm and at a rural site approximately 100 km south of the city using a glass fiber filter-polyurethane foam (PUF) collector. The samples were analyzed for polychlorinated biphenyls (PCB), DDT compounds, hexachlorocyclohexanes (HCH), hexachlorobenzene (HCB), chlordanes and polychlorocamphenes (PCC) by capillary gas chromatography with electron capture detection (GC-EDC), and for chlordanes and PCC by capillary gas chromatography-negative chemical ionization mass spectrometry (GC-MS). Geometric mean concentrations (pg m** minus **3) were: PCB (Aroclors 1242 plus 1254) equals 165, p,p prime -DDT plus p,p prime -DDE equals 7. 2, HCH equals 489, HCB equals 64, chlordane equals 8. 4 and PCC equals 25. Examination of air trajectories suggested that some of the PCC in the air over Sweden may be derived from sources in eastern Europe.
