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.
