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.

This report documents the methodology used to make air quality maps of NO2 and PM10 for the region Nord-Jæren, which includes the municipalities of Stavanger, Sandnes, Randaberg and Sola. It provides support documentation for the summary report OR 57/2013.

The report provides the annual update of the European air quality concentration maps and population and vegetation exposure estimates for human health related indicators of pollutants PM10 (annual average, 90.4 percentile of daily means), PM2.5 (annual average), ozone (93.2 percentile of maximum daily 8-hour means, peak season average of maximum daily 8-hour means, SOMO35, SOMO10), NO2 (annual average) and benzo(a)pyrene (annual average), and vegetation related ozone indicators (AOT40 for vegetation and for forests) for the year 2022. The report contains also maps of Phytotoxic ozone dose (PODY) for selected crops (wheat, potato and tomato) and trees (spruce and beech) and NOx annual average map for the same year 2022. The ozone map of peak season average of maximum daily 8-hour means is presented for the first time. The trends in exposure estimates in the period 2005–2022 are summarized. The analysis for 2022 is based on the interpolation of the annual statistics of the 2022 observational data reported by the EEA member and cooperating countries and other voluntary reporting countries and stored in the Air Quality e-reporting database, complemented, when needed, with measurements from additional sources. The mapping method is the Regression – Interpolation – Merging Mapping (RIMM). It combines monitoring data, chemical transport model results and other supplementary data using linear regression model followed by kriging of its residuals (residual kriging). The paper presents the mapping results and gives an uncertainty analysis of the interpolated maps. It also presents concentration change in 2022 in comparison to the five-year average 2017-2021 using the difference maps and exposure estimates.
