Joint Monitoring Programme (JMP). Overview of analytical methods employed by JMP in Norway 1981-1987
No full textBrief descriptions are given of the analytical methods employed by Norway under the Joint Monitoring Programme (JMP) and in cooperation with the International Council for the exploration of the Sea (ICES). Methods concern determination of trace metals and chlorinated hydrocarbons in sea water, sea bed sediment and marine organisms. Included are the detection limits, analytical laborator- ies, and references to the intercalibration exercises that applied to samples collected 1981-86
Fellesovervåkingsgruppen (JMG)-Norge. Overvåking av miljøgifter i sjøvannsmiljø. Oslofjord-området, Sørfjorden, Hardangerfjorden og Orkdalsfjord- området 1984-1985
No full textDe norske undersøkelsene innenfor Oslo- og Paris-konvensjonens felles overvåkingsgruppe (JMG) omfattet bl.a. kvikksølv (Hg), kadmium (Cd), PCB og DDT-stoffgrupper i sjøvann, skalldyr og fisk. Hg og Cd i flyndre fra Sørfjorden og PCB fra indre Oslofjorden viste overskridelser av anbefalte grenser. Hg og Cd innhold i blåskjell og torsk er noe høyere i ytre Oslofjord-området og tilstøtende områder enn indre Oslofjord, mens PCB- og DDE-innholdet var høyest i blåskjell og torskelever fra indre Oslofjord. Det ble ikke funnet noen bestemt utvikling i tiden 1981-1985 mht miljøgiftinnhold i blåskjell og torsk fra Oslofjorden
Overview of analytical methods employed by JMP in Norway 1981-92. Joint Monitoring Programme (JMP)
No full textThis report is compilation of analytical method codes and descriptions used in the Norwegian contribution to the Joint Monitoring Programme monitoring of contaminants (mainly: selected metal, organochlories, polycyclic aromatic hydrocarbons) in sea water, sea bed sediment and marin biota collected 1981-1992 and analyzed by June 1993. The method descriptions are brief and focus on the principles involved.Norwegian State Pollution Control Authority (SFT

Joint assessment and monitoring programme (JAMP). National Comments to the Norwegian Data for 1995
Full text linkThis report is part of the Norwegian contribution to the SIME 1997 meeting administrated by OSPARCOM. JAMP 1995 included the monitoring of micropollutants in blue mussels and fish at 29 and 13 stations, respectively, along the entire coast of Norway. The results indicated elevated levels of contaminants (i.e. over provinsional "high background") in: Oslofjord proper (PCBs and mercury in fish) and Langesundsfjord (HCB in mussels) and Sørfjord and Hardangerfjord (cadmium, lead, mercury and ppDDE in mussels). Significant downward trends were found for cadmium in mussels from the Sørfjord and Hardangerfjord for the period 1987-1995. An upward trend was found for mercury in mussels for the same period. Only slight overconcentration was found for cadmium in blue mussels from Orkdalsfjorden. A mussel station in a harbour at Lofoten had elevated levels of PCBs and ppDDE. The results from the reminder of stations showed primarily low levels contamination. There is evidence that the "natural" background levels of cadmium in mussels and cod (liver) may be slightly higher in the North of Norway. Introductory studies of PAH and "dioxins" in mussels were conducted. Overconcentrations of PAH were found at one station in the North of Norway. A new index was tested to assess the levels of contamination of mussels in "polluted" and "reference" areas. The index will be tested again with 1996 samples
Miljøgiftsundersøkelser i Indre Oslofjord. Delrapport 2: Miljøgifter i organismer 1992
No full textTilstanden i indre Oslofjorden 1992 var karakterisert ved delvis markert forhøyede konsentrasjoner av PCB (polyklorert bifenyler ) og DDT i blåskjell og torsk opp til 10 ganger overkonsentrasjon for PCB i blåskjell. Det ble også funnet forhøyede konsentrasjoner av PAH, bly kadmium i blåskjell minium 5-6 ganger overkonsentrasjon for PAH og mindre enn 2 ganger for bly og kadmium. Lenger ut i fjorden lå konsentrasjonene i blåskjell under eller svakt over antatte høye bakgrunnsnivåer
Contaminants in sediment 1986-92. Joint Monitoring Programme (JMP) Norwegian data NIVA samples
No full textThe report is a compilation of data used in the Norwegian contribution to the Joint Monitoring Programme and the North Sea Task Force Master Monitoring Plan for monitoring of contaminants (mainly: selected metals, organochlorines, polycyclic aromatic hydrocarbons) in sea bed sediment collected 1986-92. The samples were collected by gravity corers and along the coast from Oslofjord to Lofoten. The raw data and the mean and standard devation of parallel samples are presented
