PAH measurements at Lista. January 2020 – December 2020.
							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.
