Air quality monitoring in the border areas of Norway and Russia - progress report April 2015-March 2016. NILU rapport
The nikkel 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 program shows that air quality in Karpdalen violates Norwegian threshold values for SO2 hourly mean values in 2015, seasonal mean winter 2015/16 and hourly mean and daily mean values in 2016 (as of 31st March).

Air quality calculations for Oslo Airport. NILU rapport
Modelling of emission and dispersion shows that the largest emissions of NOX are caused by airplanes during take-off and final approach, but these emissions have little impact on ground level concentrations. The highest modelled concentration levels are located within the airport area, and are of similar size as concentrations modelled in central areas of Norwegian medium sized cities. The largest contribution comes from the aircrafts. The concentration of PM is largely decided by the background contribution. Occurrence of odour in the vicinity of the airport can be explained by the emission of hydrocarbons from aircraft in taxi-modes. Occurrence of darkening on house walls in vicinity of and further away from the airport has been investigated. It is mainly caused by growth of fungus. Investigation of possible impact from airport activity on fresh water bodies indicate that the glycol content in the use of de-icing of aircraft has the largest potential impact.
