TI  - Atmospheric transport of persistent organic pollutants (POPs) to Bjornoya (Bear 
      island).
PG  - 1082-91
AB  - A first medium term monitoring of atmospheric transport and distribution for 
      persistent organic pollutants (POPs) in Bjornoya (Bear island) air samples has 
      been performed in the period between week 51/1999 and week 28/2003. A total of 50 
      single compounds consisting of polychlorinated biphenyls (33 congeners), 
      hexachlorobenzene (HCB), hexachlorocyclohexane isomers (alpha-, beta-, 
      gamma-HCH), alpha-endosulfan, cyclodiene pesticides (chlordanes, 
      nonachlor-isomers, oxy-chlordane, heptachlor and chlordane) as well as 
      dichlorodiphenyltrichloroethane (DDT) derivatives were analysed and quantified. 
      Atmospheric transport of POPs was identified as an important contamination source 
      for the island. PCBs, HCB and HCH isomers were the predominant POP groups, 
      contributing with 70-90% to the overall POP burden quantified in the Bjornoya air 
      samples. The highest concentration levels for a single compound were found for 
      HCB (25-35 pg m(-3)). However, the sum of 33 PCB congeners was found to be in the 
      same concentration range (annual means between 15 and 30 pg m(-3)). Cyclodiene 
      pesticides, DDT derivatives and alpha-endosulfan were identified as minor 
      contaminants. Several atmospheric long-range transport episodes were identified 
      and characterised. Indications for industrial emissions as well as agricultural 
      sources were found for the respective atmospheric transport episodes. A first 
      simple statistical correlation assessment showed that for long-range transport of 
      pollution, the local meteorological situation is not as important as the air mass 
      properties integrated over the time period of the transport event. The local 
      weather situation, on the other hand, is important when investigating deposition 
      rates and up-take/accumulation properties in the local ecosystem. Based upon 
      chemical data interpretation, valuable information about the influence of primary 
      and secondary sources on the air mass contamination with chlorinated insecticides 
      (e.g., HCHs) was found and discussed. The interdisciplinary interpretation of 
      contaminant data using statistical methods, chemical analysis, meteorological 
      modelling and classical meteorological information for a comprehensive evaluation 
      of atmospheric long range transport into the European Arctic (Bjornoya) has 
      proven to be a highly versatile tool not only for atmospheric scientists but also 
      with strong potential for regulatory purposes.
