Air quality measurements in the vicinity of Finnfjord AS. NILU OR
NILU was assigned by Finnfjord AS to carry out measurements of SO2 and NO2 at 15 locations in the Finnfjord area. The monthly concentrations which were measured in the period october 2011 ¿ april 2011 were assessed with respect to Klif¿s recommended air quality criteria and EU limit values, as well as existing model results. The results were also compared to similar measurements performed in 1996.
The halfyear average concentrations of SO2 and NO2 are significantly lower than the recommended air quality criteria and ranged between 2,2 µg/m3 and 4,0 µg/m3 for SO2, with the highest values close to the smelter. For NO2, the halfyear average was between 1,8 µg/m3 and 6,8 µg/m3, with the highest concentration occurring in Finnsnes. Some locations on Senja showed higher concentrations of both SO2 and NO2 than in the Finnfjord area.
The concentration distribution of SO2 and NO2 mapped as result of the measurements differs from the model results, where the highest levels are exected between Finnfjord AS and Gisund bridge and in the direction of Rossfjordvatnet.

Monitoring of long-range transported air pollutants. Annual report for 2011. NILU OR
Air and precipitation chemistry is determined through various monitoring programmes at several sites located in the rural areas of Norway. This report describes the results for 2011, and these are compared to the previous years.

The NORTRIP model is the result of research efforts carried out by a number of Nordic institutes to improve our understanding and ability to model non-exhaust traffic emissions and has been developed through the Nordic Council of Ministers project NORTRIP (NOn-exhaust Road Traffic Induced Particle emissions). The NORTRIP model is a process based non-exhaust emission model that is intended for application without site specific empirical factors. It takes into account direct wear emissions, the build up of mass on the road surface, the suspension of this mass, as well as the application and suspension of salt and sand. It combines a road dust sub-model with a road moisture sub-model in order to properly describe the retention of dust on the road surface. The model can be applied for assessment purposes and for the management and evaluation of abatement strategies regarding road wear, salting and sanding. The model development and its documentation, along with its application to a large number of Nordic datasets, is described in detail in this report.
