Målinger av luftkvalitet i Kongsberg. NILU OR
NILU har målt forurensning i Kongsberg sentrum på oppdrag fra Kongsberg kommune. Måleserien er sammenlignet med samtidige målinger på Lillehammer. Målingene viser at forurensningsnivået i Kongsberg sentrum er lavere enn forurensningsnivået på Lillehammer.

The geographic distribution of NO2-concentrations in air in the area around E16 Arna – Vågsbotn (Bergen) was mapped by
NILU after request by Statens vegvesen. Measurements were carried out with passive air samplers at 10 sites in the area
Gaupås-Kalsås-Blinde. The project was carried out in winter (28. January – 24. March 2020) in an area which often is subject to inversion conditions in wintertime.
The winter 2019-2020 proved to be a mild winter, no inversion conditions were registered. The NO2-concentration was highest in the first week and decreased gradually every week. During the two last weeks, traffic was reduced as a consequence of pandemia measures. The average concentration at the most polluted site over the entire measurement period was 22.9 μg/m3. Comparison of results from the measurement area with observations from monitoring stations in Bergen showed that the NO2-level close to E16 was as high as at traffic stations in Bergen.
