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 long-range transported air pollutants in Norway, annual Report 2016. NILU report
This report presents results from the monitoring of atmospheric composition and deposition of air pollution in 2016, and focuses on main components in air and precipitation, particulate and gaseous phase of inorganic constituents, particulate carbonaceous matter, ground level ozone and particulate matter. The concentration levels were generally low in 2016 compared to previous years.

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.

Screening programme 2016 - Selected compounds with relevance for EU regulation. NILU report
This report summarizes the findings of a screening study into the occurrence of selected solvents, siloxanes, flame retardants, bisphenols and other PBT compounds in effluents, sewage sludge, surface water, sediments, house dust, indoor air and biota.

Air quality monitoring in the border areas of Norway and Russia - progress report 2016. NILU rapport
The nickel smelters in NW Russia emit large quantities of sulphur dioxide (SO2) and heavy metals. These emissions lead to enhanced concentrations of environmental pollutants in the border areas. The monitoring programme shows that air quality in Karpdalen violates Norwegian limit values for SO2 hourly mean values and daily mean values in 2016, as well as seasonal mean winter 2015/16.

Johan Castberg oil field - Assessment of emissions to air. NILU rapport
The environmental impact of future emissions from activities at the Johan Castberg oil field has been investigated. Concerning emissions of CO2, CH4 og NMVOC, the total emissions rank Johan Castberg as a medium size field in Norway. For NOX and SOX, the environmental impact from deposition is considered to be small. Concerning formation of ozone from NOX emissions, the model estimates give an increase of N120 (number of days with 8-hrs running mean value higher than 120 µg/m3 ), up from 10 to 11. Effects of Black Carbon emissions from Johan Castberg is also estimated, and the climate impact is considered to be small.

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.

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.

Screening of PFAS and Dechlorane compounds in selected Arctic top predators. NILU report
This report summarizes the findings of a screening study into the occurrence of selected perfluorinated compounds (PFCs) and dechloranes in Arctic top predators. The emerging PFCs F53 F53B, and PFBS were not detected neither in bird eggs nor in mammals. However, different dechloranes were detected in all samples.

Monitoring of greenhouse gases and aerosols at Svalbard and Birkenes in 2016 - Annual report. NILU report
The report summaries the activities and results of the greenhouse gas monitoring at the Zeppelin Observatory situated on Svalbard in Arctic Norway during the period 2001-2016, and the greenhouse gas monitoring and aerosol observations from Birkenes for 2009-2016.

Målinger i Lillestrøm sentrum for utredning av hovedkilder til svevestøvforurensning. NILU rapport
A measurement project to investigate the main pollutants that contribute to PM pollution in Lillestrøm was conducted during the period February - April 2017. The project was a collaborative research project with Skedsmo municipality. Measurements of particulate matter (PM2.5, PM10), light absorption of particles (black carbon, BC) and particle size distributions were conducted in Vollaparken in the centre of Lillestrøm. An important source of PM was combustion, i.e. diesel engines and wood burning. For PM10 also resuspension of road dust is an important contribution. During the measurement period, traffic emissions were the main contribution from combustion. It was relatively mild during the measurement period and stable inversion periods were not observed. Therefore, the contribution from wood burning was low and there were no pollution episodes due to accumulation of emissions.

Air quality plan for improved air quality in Bergen. NILU rapport
The air quality plan will help to reduce the air pollution to a level that meets the requirements of the pollution regulations. This revised action plan includes air quality calculations for Bergen for NO2, PM10 and PM2.5 for the present situation (2015) and scenario calculations for the year 2021 following a business as usual (BAU) emission scenario. Mitigation scenario calculations of air quality in 2021, with the introduction of a new set of measures to control pollution levels Bergen, were also carried out. Based on the results of the calculations and in dialogue with Bergen municipality and stakeholders, a revised 10-point action program has been proposed to be addressed politically.

Deposition of major inorganic compounds in Norway 2012-2016. NILU report
This report contains estimates of atmospheric deposition of major inorganic compounds in Norway for the period 2012 to 2016 using two different methods, one observational based method while the other combining atmospheric transport model with observations. Both methods show similar clear spatial gradient in the atmospheric deposition with highest loads in south and south-west. The combined method has improved the spatial information of the deposition pattern for wet deposition. For dry deposition, there are quite large uncertainties in the estimated dry deposition velocities in both methods. Compared to the previous period 2007-2011, there is a decrease in the total sulfur deposition in Norway of 9%. For total nitrogen there are minor changes. Compared to the 1978-1982 period, the reductions in sulfur and nitrogen depositions are 75% and 20% respectively.

Additional measurements at Nationaltheatret station. NILU rapport
Measurements of indoor environment at theNarvesenkiosk, Nathionaltheatret station show no exceedance of the guidelines for relative humidity and CO2. The guideline for temperature is overheld exept for a few hours during the night between 6 April and 7 April. All the samples of fugitive dust concentrations had concentrations that exceeded the guideline for PM2.5 concentrations in indoor environment.
