Intercomparison of BTEX measurements and revision of historical BTEX data in Oslo. NILU OR
Parallel measurements of BTEX with diffusive sampling in Oslo confirmed large deviations between the two involved laboratories NILU and Molab. The following investigation identified that Molab was using wrong uptake rates in their final calculation of the results. All BTEX results delivered by Molab between 2008 and 2014 have to be revised downwards with factors between 2,4 and 2,9.

Russian-Norwegian ambient air monitoring in the border areas. Report M-322
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 Zapoljarny and the Norwegian stations in Karpdalen and Svanvik. MUGMS and NILU use internationally well recognized the state-of-the-art methods for analyzing both SO2 and heavy metals. SO2 emissions and ambient air levels have decreased over the last two decades, but elevated levels of SO2 were observed in Nikel and Zapoljarny in the period 2009-2012, exceeding the Russian norms.
The border areas in Norway experienced levels of SO2 exceeding the Norwegian air quality standards over the years 2011-2012. The levels of heavy metals did not exceed neither the Russian norms for heavy metals, nor the Norwegian annual mean target values for heavy metal. The levels of both SO2 and heavy metals were higher at the Russian stations than the Norwegian stations. The Russian monitoring stations are located closer to the emission sources in Nikel and Zapoljarny.

Johan Castberg oil field - Assessment of emissions to air. NILU OR
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. Emissions of Black Carbon is also estimated, and the climate impact is considered to be small.
