Esso Slagen refinery - Monitoring program 2006-2011. NILU OR
NILU - Norwegian Institute for Air Research has been conducting a monitoring pogram for Esso (ExxonMobile) at Slagen refinery from 2006-2011. The program included monitoring of meteorology, SO2, PM10, BTEX and rain water chemistry. Results show that air quality standards for SO2 were exceeded in 2009, both concerning hourly mean values (29 values above 350 µg/m3), daily mean values (five values above 125 µg/m3) and annual mean (20,3 µg/m3 vs 20 µg/m3). For the other components there were no exceedence of air quality standards, except for benzene in 2009 (2,6 µg/m3 vs national target value of 2 µg/m3).

Emissions from domestic heating due to woodburning are one of the main emissions sources of PM in Norway. However there are uncertianties in the emission data and especially how much these emissions contribute to the concentrations. Dispersion modeling has been performed for Oslo with different emission scenarios to test some of the parameters related to this emission source. The model results show that the wood burning contribution is overestimated, especially in the evening and conclusions are that the emissions of wood burning are wrong both in quantity as well as spacial distribution in time variation.
