  1. Persistent Organic Pollutants (POP) in Bjørnøya snow, ice and fog Roland Kallenborn Norwegian Institute for Air Research (NILU), NO-2027 Kjeller Guttorm Christensen, Dennis Gregor Akvaplan-niva, NO-9296 Tromsø Ice-Snow workshop, Brno, CZ: 4-7.11.04

  2. Alpine and Arctic regions Ice-Snow workshop, Brno, CZ: 4-7.11.04

  3. Transport and deposition According to MacDonald R.W. Contaminants, global change and cold regions. In. Ørbæk J.B., Kallenborn R. & Tombre I.M. (Editors) Environmental Challenges in Arctic-Alpine Regions, Springer Vlg. In preparation. Exp. release spring 2005. Ice-Snow workshop, Brno, CZ: 4-7.11.04

  4. Bjørnøya radio Øyangen Ellasjøen N 2 km 0 1 Contour interval 100 m Bjørnøya (Bear Island): a case study Ice-Snow workshop, Brno, CZ: 4-7.11.04

  11. Conclusions • Bjørnøya is a ”hot spot” region for POP contamination in the Arctic. • Levels of POPs in the abiotic environment in Bjørnøya are considerable. • The POP patterns in snow,precipitation and fog are characterised by a surprisingly high variability. • Lakewater samples are contaminated but the POP patterns are relatively stable. • Fog and snow/rain precipitation play play a major role in the deposition process for POPs on Bjørnøya Ice-Snow workshop, Brno, CZ: 4-7.11.04

  12. Aknowledgement The help and support of many colleagues is highly appreciated: The Norwegian Coast guard supported us with transport of equipment and research scientists. The crew of the meteorological station at Bjørnøya help with infrastructure and sample collection. The Research Council of Norway and the State pollution control Authorities supported the Project economically. Anita Evenset (Akvaplan-niva) helped during the field campaign, Dorte Herzke and Urs Berger (NILU) have performed a part of the anaytical work. Martin Schlabach (NILU) helped during the analytical work. Ice-Snow workshop, Brno, CZ: 4-7.11.04
