Environmental Contaminants in an Urban Fjord, 2018
This programme, “Environmental Contaminants in an Urban Fjord” has covered sampling and analyses of sediment and organisms in a marine food web of the Inner Oslofjord, in addition to samples of blood and eggs from herring gull and eider duck. The programme also included inputs of pollutants via surface water (storm water), and effluent water and sludge from a sewage treatment plant. The bioaccumulation potential of the contaminants in the Oslo fjord food web was evaluated. The exposure to/accumulation of the contaminants was also assessed in birds. A vast number of chemical parameters have been quantified, in addition to some biological effect parameters in cod, and the report serves as valuable documentation of the concentrations of these chemicals in different compartments of the Inner Oslofjord marine ecosystem.

Environmental pollutants in the terrestrial and urban environment 2018
Samples from the urban terrestrial environment in the Oslo area were analysed for various inorganic and organic
environmental pollutants. The selected species were earthworm, fieldfare, sparrowhawk, brown rat, red fox and
badger. Air and soil samples were also included in the study to further the understanding on sources and uptake of
pollutants. A foodchain approach was used to investigate trophic magnification of the different compounds.

This report studies the distribution and fate of contaminants such as mercury (Hg), cyclic volatile methylated siloxanes (cVMS: D4, D5, D6), brominated flame retardants (BFR, PBDEs), alkylphenols, organic phosphorous flame retardants (oPFR), poly- and perfluorated alkyl substances (PFAS), new brominated flame retardants (nBFR) and UV-chemicals. Samples of the pelagic food web of Lake Mjøsa (zooplankton, Mysis, vendace, European smelt and brown trout) and the top predator brown trout in Lake Femunden are studied. Results are compared to environmental quality standards (EQS) and the time trends for major contaminants are studied.

Instrumenter som skal brukes til måling av lokal luftkvalitet i henhold til forurensningsforskriften skal være godkjente for dette formålet. Norge har per i dag ingen godkjenningsordning. Inntil videre godkjennes derfor de instrumenter som det svenske referanselaboratoriet for luft har godkjent.
Denne rapporten beskriver hvordan en godkjenningsordning kan etableres i Norge, basert på rutinen brukt i Sverige, gjennom å belyse den lovmessige forankringen og prosedyren for typegodkjenning. Oppgavene og ansvarsfordelingen mellom den ansvarlige forvaltningsmyndigheten (Miljødirektoratet) og Referanselaboratoriet er forklart.

Spredningsberegninger for ammoniakkutslipp. Leangen idrettsanlegg i Trondheim.
NILU har gjennomført spredningsberegninger for utslipp av ammoniakk (NH3) ved Leangen idrettsanlegg I Trondheim. Beregningene er utført for å undersøke hvilke konsentrasjoner av ammoniakk som kan forekomme i bakkenivå for ulike høyder av avkast for ammoniakkdamp. Beregningene viser at avkastet bør være 21 m over bakkenivå for å overholde grenseverdi for arbeidsatmosfære. Så lenge utslippet pågår vil det forekomme timemiddelkonsentrasjoner av ammoniakk over luktegrensen nedvinds for utslippet.
