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.

The effect of selected amines on the corrosion of carbon steel and copper was investigated in the laboratory and in the field. The steel and copper samples were exposed to loads of the amines in the laboratory, representing possible 10 years maximum real exposure due to emission from a CO2 capturing plant, and to higher doses in the laboratory and in the field. No effect on the corrosion rate for steel was detected for the application of a possible 10 years real maximum dose of the amines in the laboratory as compared to blanks. Application of 700 times higher doses of amines in the laboratory was observed to give anodic protection, and thus reduced corrosion, of steel samples, but to dissolve the surface of a copper sample. The anodic protection was due to the formation of an amine surface film that protected the sample form oxidation. The dissolution of copper was probably due to formation of a copper-amine complex at high pH. A slight increase in corrosion was observed for samples that were exposed to the equivalent of possible 65 years maximum real exposure of amines in the field. This may be explained by freezing point depression and increased time of wetness of the sample surfaces due to accumulation of the amine solute on the sample surfaces in the season with frost.
