Kartlegging av svevestøv i datasenter på Fet. Måling av PM10 og PM2,5 hos Digiplex. NILU rapport
NILU was commissioned by Digiplex to map the presence of airborne dust in their data centre located at Fet, Romerike. The purpose of the project was to map the concentrations of airborne dust (PM10and PM2,5 )in a corridor and a server room, as well as assess the results against recommended values given by FHI and limit values given by the Ministry of Labour and Social Affairsin 'Forskrift for tiltaks-og grenseverdier'. Generally, the measured concentrationsof both particle fractions were very low. All measured concentration of PM2,5 lies far below FHI's recommended values for PM2,5 in indoor air. 8-hour average measured for PM10shows a concentration level far lower than the limit value given by Arbeids- og sosialdepartementet in 'Forskrift for tiltaks-og Grenseverdier'. This also applies to the measured concentration of Zn as compared to the limit value given in the same regulation.

Målinger i Lillestrøm sentrum for utredning av hovedkilder til svevestøvforurensning. NILU rapport
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.
