Summary: A measurement project to investigate the main pollutants that contribute to PM pollution in Lillestrøm was conducted during the period February - April 2017. The project was a collaborative research project with Skedsmo municipality. Measurements of particulate matter (PM2.5, PM10), light absorption of particles (black carbon, BC) and particle size distributions were conducted in Vollaparken in the centre of Lillestrøm. An important source of PM was combustion, i.e. diesel engines and wood burning. For PM10 also resuspension of road dust is an important contribution. During the measurement period, traffic emissions were the main contribution from combustion. It was relatively mild during the measurement period and stable inversion periods were not observed. Therefore, the contribution from wood burning was low and there were no pollution episodes due to accumulation of emissions.
