On behalf of Aluminiumindustriens Miljøsekretariat (AMS) and Alcoa Lista, NILU – Norwegian institute for air research has conducted a sampling campaign in the surroundings of the Alcoa Lista aluminium smelter in order to update the knowledge on PAH-concentrations around the smelter today. Samples were taken in the period January – December 2020 and analysed for particle bound PAHs. As a consequence of reduced emissions compared to earlier measurements, the ambient concentrations of benzo(a)pyrene (BaP) were reduced. BaP had an annual average concentration below the target value at both sampling sites. At Huseby, the lower assessment threshold was exceeded. PAH-levels in the area were similar to those observed in Norwegian cities.
