NILU has carried out an investigation of contributions from small scale wood burning to PM concentrations in air in cities in Norway. In this project phase (Phase 2a) the contributions from wood burning in Oslo on days with PM >50 ¿g/m3 has been studied.
While wood burning contributes about 35% to PM2.5 and 20-25% to PM10 as winter average, the contribution on high PM10 days can be as high as 50%, making wood burning the main contributor.

NILU has carried out an investigation of contributions from small scale wood burning to PM concentrations in air in cities in Norway. In this project phase 2B the contributions to PM in Trondheim from small scale wood burning have been studied.
There were days with high PM concentrations in Trondheim that winter, up to and above 100 µg/m3 of PM10. On days with probable large contributions from wood burning particles, the PM2,5 and PM10 could be over 50 µg/m3 .
Due to analysis problems with the wood burning tracer component (an unexplained interference peak) the wood burning contribution could not be determined quantitatively.
