NILU har vurdert spredning av utslipp til luft fra Finnfjord AS sitt smelteverk ved Finnsnes. Bakgrunnen er oppdaterte krav fra Miljødirektoratet. Fokus i studien er på NOx, SO2 og støv/partikler. Det er utført lokale spredningsberegninger ved hjelp av modellen CONDEP. Regionale beregninger av konsentrasjoner og avsetning er utført med WRF-EMEP modellsystemet. En stor andel av forurensningen slippes ut fra tak. Dette kan gi turbulens og bygningsnedtrekk som igjen gir høye konsentrasjoner rett ved smelteverket og i umiddelbar nærhet. CONDEP-beregningene viser at for NO2 og støv/PM er norske grenseverdier overholdt. For SO2 kan overskridelse av grenseverdier oppstå opptil 500-600 m fra smelteverket. WRF-EMEP-beregningene viser liten påvirkning på regional skala. Av utslippene fra Finnfjord AS avsettes 16 % av nitrogen, 15 % av svovel og 12 % av PM innenfor det innerste gridet (105 x 105 km2). Det gis også anbefaling om målinger av SO2 og meteorologi for å tallfeste påvirkningen fra Finnfjord AS på omgivelsene.

Grøntoft, T.; Ofstad, T.

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.

Final report: Air quality management feasibility study for Armenia. NILU OR

Randall, S.; Tønnesen, D.; Liu, L.

A Feasibility Study has been performed to assess the Air Quality Management (AQM) situation in Armenia for the purpose of potentially preparing a future comprehensive project proposal for establishing an Air Quality Management Program (AQMP) for the country. The study was conducted in cooperation with local Armenian Environmental authorities (primarily the Environmental Impact Monitoring Centre - EIMC) to evaluate the existing local monitoring network and collaborating institutions, in addition to performing a screening study in Yerevan based on passive samplers. Results from the study indicate that Armenia needs technical support and training in order to establish a comprehensive AQMP. Recommendations, including a detailed roadmap, are presented as suggestions for the framework of a future proposal to establish a successful AQMP in Armenia.
