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.

Atmospheric deposition of organic contaminants in Norway: National moss survey 2015. NILU report
For the second Norwegian Moss survey on organic contaminants 20 samples were collected on the Norwegian mainland in rural areas presumably little affected by local point sources of pollutants. PeCB, HCB, PCB, HCH, DDT, PBDE, DBDPE, HBCD, PFAS, and PAH were determined. There is a general trend of decreasing contamination from 2010 to 2015 for the POPs included in the survey. A trend of decreasing contamination with increasing latitude shown in the 2010 moss data is confirmed in the results from 2015. The results for PCB indicate release from local sources in the Oslo area.

Atmospheric deposition of heavy metals in Norway. National moss survey 2015. NILU report
Commissioned by the Norwegian Environment Agency, NILU - Norwegian Institute for Air Research in collaboration with Norwegian University of Science and Technology (NTNU), collected moss from 230 sites and determined the content of 53 metals in these. The purpose of the survey is to map atmospheric deposition of heavy metals in Norway. Compared with data from 2005, a decrease is observed in the deposition of vanadium and lead. For chromium, nickel, copper, zinc, arsenic, cadmium and antimony, there is no appreciable change in deposition from 2005 to 2015

Workshop on emerging pollutants in non-industrial indoor environments. NORMAN workshop report. NILU report
This workshop aimed to identify the current state of the art plus knowledge gaps and needs within the research field of CECs, covering both ¿old¿ and emerging SVOCs and NVOCs in non-industrial indoor environments. Further, it aimed to promote awareness of emerging pollutants in non-industrial indoor environments and the exchange of knowledge/ information, and to encourage enhanced collaboration by bringing together scientists in the field of CECs in indoor environments with expertise from building and consumer product sectors and stakeholders/regulatory authorities.
