Environmental pollutants in the terrestrial and urban environment 2016. NILU report
We analysed biological samples from the terrestrial and urban environment for various inorganic and organic contaminants in the Oslo area. A foodchain approach was used, in order to detect bioaccumulation of the different compounds. The species analysed were earthworms, fieldfare, sparrowhawk, brown rat, tawny owl and red fox. Air and soil samples were also included in the study to increase the understanding on sources and uptake of pollutants.

Russian-Norwegian ambient air monitoring in the border areas. Updated joint report 2010 - 2015.
The report presents the levels of sulphur dioxide (SO2) and heavy metals (nickel and copper) in ambient air at the Russian monitoring stations in Nikel and Zapoliarny and the Norwegian monitoring stations in Karpdalen abd Svanvik in 2010-2015.
MUGMS and NILU use internationally well recognized state-ofthe-art methods for analyzing both SO2 and heavy metals. Concerning SO2, the monitoring methods and limit values are comparable. The sampling methods and limit values for heavy metals are different. It makes it challenging to compare the results for heavy metals. The expert group exchange information and knowledge, and try to achieve harmonized methods. Emissions of SO2 in ambient air have decreased over the last two decades, but elevated levels of SO2 were observed in Nikel and Zapoliarny, exceeding the Russian norms. Monitoring results from the Norwegian border areas show that the levels of SO2 were exceeding the Norwegian air quality standards. The levels of heavy metals did not exceed neither the Russian norms for heavy metals, nor the Norwegian annual mean target values for heavy metals. The registered levels of both SO2 and heavy metals in ambient air were higher at the Russian stations than the Norwegian stations. The Russian monitoring stations are located closer to the emission sources in Nikel and Zapoliarny.

Monitoring of environmental contaminants in air and precipitation, annual report 2016. NILU report
This monitoring report presents 2016 data and time-trends for the Norwegian programme for long-range atmospheric transported contaminants. The results cover 122 organic compounds and 11 heavy metals. The organic contaminants includes regulated persistent organic pollutants (POPs) as well POP-like contaminants not yet subjected to international regulations.

Monitoring of the atmospheric ozone layer and natural ultraviolet radiation. Annual report 2016. NILU report
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 the 1979-1989 average. There are large inter-annual variations and in 2016 there were relatively low values at all the three Norwegian stations, especially in February/March.

Air quality modelling in Oslo - input to the revised action plan on air quality for Oslo 2017-2020. NILU rapport
NILU has estimated the air quality levels in Oslo in 2020, as well as the expected impacts of a set of measures on the air quality. The results of the model calculations will be incorporated in the revised action plan for air quality in Oslo 2017-2020.
