Air Quality in Ny-Ålesund. Monitoring of Local Air Quality 2018.
The concentrations of the measured components are generally low and below national limit values for the protection of
human health and critical levels for the protection of vegetation.
Wind from northern sectors gave the highest average concentrations of nitrogen oxides and sulphur dioxide, which
indicates the power station and the harbour as possible sources. The measurement results for CO2 show an annual variation with higher concentrations in the winter and lower in summer. Measured concentrations of CO were most likely caused by local snowmobile traffic.

Monitoring of the atmospheric ozone layer and natural ultraviolet radiation. Annual Report 2018.
This report summarizes the results from the Norwegian monitoring programme on stratospheric ozone and UV radiation
measurements. The ozone layer has been measured at three locations since 1979: in Oslo, Tromsø/Andøya and Ny-Ålesund.
The UV measurements started in 1995. The results show that there was a significant decrease in stratospheric ozone above
Norway between 1979 and 1997. After that the ozone layer stabilized at a level ~2% below pre-1980 level. 2018 was
characterized by low summer ozone values in Oslo and a record high annual integrated UV-dose.

Skogens helsetilstand i Norge. Resultater fra skogskadeovervåkingen i 2018
Skogens helsetilstand påvirkes i stor grad av klima og værforhold, enten direkte ved tørke, frost og vind, eller indirekte ved at klimaet påvirker omfanget av soppsykdommer og insektangrep. Klimaendringene og den forventede økningen i klimarelaterte skogskader gir store utfordringer for forvaltningen av framtidas skogressurser. Det samme gjør invaderende skadegjørere, både allerede etablerte arter og nye som kan komme til Norge i nær framtid. I denne rapporten presenteres resultater fra skogskadeovervåkingen i Norge i 2018 og trender over tid for følgende temaer: (i) Landsrepresentativ skogovervåking; (ii) Skogøkologiske analyser og målinger av luftkjemi på de intensive overvåkingsflatene; (iii) Overvåking av bjørkemålere i Troms og Finnmark; (iv) Granbarkbilleovervåking – utvikling av barkbillepopulasjonene i 2018;
(v) Ny barkbille på vei – vil den like klimaet?; (vi) Phytophthora i importert jord på prydplanter og faren det utgjør for skog; (vii) Overvåking av askeskuddsyke; (viii) Skog- og utmarksbranner i 2018; (ix) Andre spesielle skogskader i 2018...….

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.

Monitoring of environmental contaminants in air and precipitation, annual report 2018
This report presents environmental monitoring data from 2018 and time-trends for the Norwegian programme for Long-range atmospheric transported contaminants. The results cover 200
organic compounds (regulated and non-regulated), 11 heavy metals, and organic chemicals of potential Arctic concern.

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.
