Elevated stratopause events in the current and a future climate: A chemistry-climate model study
Elsevier
2021
On behalf of Aluminiumindustriens Miljøsekretariat (AMS), NILU – Norwegian Institute for Air Research has conducted a sampling campaign in the surroundings of the Hydro Sunndal aluminium smelter in order to update the knowledge on air quality around the smelter today. Samples were taken in summer 2019 and analysed for PM2.5, PM10, metals (Pb, Cd, Cr, Ni, As, Al, V, Ga, Sb, Bi), particle-bound PAHs, SO2, particle-bound and gaseous fluorides. As a consequence of reduced emissions compared to earlier measurements, the ambient concentrations of PM10, Cr, Pb, BaP (for PAHs), SO2 and fluorides were strongly reduced. All measured compounds had concentrations below limit values and recommended
guideline values.

Spredningsberegninger av luftforurensning fra Årdal Metallverk
Rapporten presenterer oppdaterte spredningsberegninger for utslipp til luft fra Årdal Metallverk i Øvre Årdal. Utslippene er hentet fra utslippstillatelsen som en vurdering av «worst-case». Det er beregnet bakkekonsentrasjoner for SO2, støv og fluorider, samt metallkomponentene i utslippstillatelsen. Beregningene, som er basert på en konservativ metodikk, viser potensielt overskridelse av målsetningsverdier for nikkel og arsen i nærområdet til anlegget ved nivåene i utslippstillatelsen. Beregningene gir også fare for overskridelse for støv, men vurderingen er usikker fordi verken andelen PM2,5 og PM10 i utslippet eller bidraget fra øvrige kilder er kjent.
