BeskrivelseThis report is part of the Norwegian contribution to the SIME 2001 meeting administrated by OSPAR. JAMP 1999included the monitoring of micropollutants in blue mussels (45 stations) and fish (16 stations) along the coast ofNorway from Oslo to Bergen, Lofoten and Varangerfjord. The results indicated elevated levels of contaminants(i.e. over provisional “high background”) in: Oslofjord proper (PCBs, ppDDE and mercury in fish) andLangesundsfjord (HCB in mussels) and Sørfjord and Hardangerfjord (cadmium, lead, mercury and ppDDE inmussels). A significant upward trend were found for mercury in cod from the inner Oslofjord and downward trendswere found for cadmium and lead in mussels from the Sørfjord and Hardangerfjord for the period 1987-1999. Theresults from the remaining stations showed low or moderately levels of contamination. No change in “pollution” or“reference” index classification was found from 1997 to 1999. Studies were also conducted in two areas on thesouthern/south-western coast using biological effects methods in cod (6 stations), flatfish (5 stations) andimposex/intersex in dogwhelks (6 stations). Concentrations of organotin in mussels and imposex in dogwhelks werestill apparent, especially in the Haugesund area compared to the 1998 investigation.
