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.

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.

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.

This report presents the ICP Materials database for the period October 2014 - October 2015. It includes environmental data from the ICP Materials trend exposure programme for 2014 - 2015. The database consists of meteorological data (T and RH) and pollution data as gas concentrations, amounts of ions in precipitation, particle concentrations and amounts of particle deposition.

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.

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.
