On behalf of Hav Eiendom, NILU – Norwegian Institute for Air Research carried out measurements of particulate matter (PM10) in Lohavn in Oslo. The area will be developed into a new urban area with residential buildings, school, outdoor areas and businesses. The PM-concentration was measured at three locations in Lohavn to map the PM-distribution and possible sources. The measurement project took place in spring 2020. Possible effects of Covid-shutdown, variations in amount of traffic in the area and meteorological variations on the PM concentration are discussed.

The measurement results show a lower PM-concentration than in the measurement period 2016/17. The reason was probably the disappearance of temporary sources which led to periodically high concentrations in 2016/17. The highest PM10-concentrations were observed with winds from the south-southwest (which dominates during the day).
