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.

PAH measurements in air and moss around selected industrial sites in Norway 2015. NILU report
On request from the Norwegian Environment Agency a pilot study of atmospheric deposition of PAH around industrial enterprises in Norway has been carried out. The participation was voluntary and 10 industries located at 10 different sites financed their own participation. The survey is based on analysis of samples of naturally growing moss collected around the enterprises during the summer of 2015. In addition, passive air samplers for collection of volatile PAH were placed around 6 of the participating enterprises. Generally, the PAH level determined in moss collected around industrial sites were considerably higher than the PAH level found in moss collected at background sites. The levels of PAHs found in the air samples was low and often at the same level as found at the closest background site, for all out of two sites, i.e. Sunndal and Kristiansand. There is no clear indication that the industry is the only source to the levels of PAHs in moss. Hence, results from this pilot study, illustrates that moss and air samples together provide a more comprehensive information regarding the spatial distribution of PAH around the industrial sites.
