Fish  livers  from  the  North  and  Baltic  Sea:
•  Fish  was  caught  during  the  following  monitoring  expeditions:  Cruise  no.  242  of
FFS  “Walter  Hering  III”  from  22  August  to  8  September  2002  and  no.  255  from  25
August  to  9  September  2004.
•  Five  to  six  sampling  sites  were  selected  in  the  North  and  Baltic  Sea  (see  Table  25
and  Figure  12,  Figure  13,  Figure  14  for  details)
•  Fish  livers  were  collected  from  North  Sea  dab  (Limanda  limanda),  flounder
(.Platichthys  flesus)  and  cod  (Gadus  morhua).  Totally  60  single  samples  were
obtained.
•  Detection  limits  of  ca.  10  ng/g  (total  sPCA)  required  minimum  5  g  of  sample.  This
made  pooling  of  up  to  five  liver  samples  necessary.
•  More  details  about  sampling  is  given  in  the  appendix  under  sampling  details.

Cod  liver  from  the  northern  North  Atlantic
•  Caught  in  2003  at  the  north  and  south  coast  of  Iceland  and  the  Lofot  Islands.
•  Totally  six  samples  delivered  by  the  Norwegian  Institute  for  Air  Research  (Dr.  Urs

Fish  and  sea  birds  from  Bear  Island
•  Bear  Island  is  known  as  a  site  of  elevated  concentrations  of  polychlorinated
compounds  (PCBs,  DDT,  toxaphenes)  due  to  long  range  transport  and  on-site
bioaccumulation  (Evenset  et  al.,  2002;  Evenseth  el  al.,  2004).
•  Sampling  was  carried  out  in  2001  by  Aquaplan-NIVA  (Tromsp,  Norway,  Dr.
Guttorm  Christensen).
•  Two  liver  and  muscle  tissue  samples  from  Arctic  char  (Salvelinus  alpinus)  from
Lake  Ellasjpen,  two  samples  each  of  liver  and  muscle  tissue  from  little  auk  (.Alle
alle),  kittiwake  (Rissa  tridactyla),  glacous  gull  (Larus  hyperboreus),  see  Table  25
further  details  and  Figure  9  for  site  description.
