PAH measurements in air and moss around selected industrial sites in Norway 2015. NILU report
On request from the Norwegian Environment Agency a pilot study of atmospheric deposition of PAH around industrial enterprises in Norway has been carried out. The participation was voluntary and 10 industries located at 10 different sites financed their own participation. The survey is based on analysis of samples of naturally growing moss collected around the enterprises during the summer of 2015. In addition, passive air samplers for collection of volatile PAH were placed around 6 of the participating enterprises. Generally, the PAH level determined in moss collected around industrial sites were considerably higher than the PAH level found in moss collected at background sites. The levels of PAHs found in the air samples was low and often at the same level as found at the closest background site, for all out of two sites, i.e. Sunndal and Kristiansand. There is no clear indication that the industry is the only source to the levels of PAHs in moss. Hence, results from this pilot study, illustrates that moss and air samples together provide a more comprehensive information regarding the spatial distribution of PAH around the industrial sites.

Air quality in Norwegian cities in 2015. Evaluation report for NBV main results. NILU report
Beregningsverktøyet er utviklet som et samarbeid mellom NILU ¿ Norsk institutt for luftforskning og Meteorologisk institutt (MET), under ledelse av Miljødirektoratet og i samarbeid med Vegdirektoratet, Helsedirektoratet og Folkehelseinstituttet. Arbeidet begynte i 2014 på oppdrag fra Klima- og miljødepartementet (KLD), Samferdselsdepartementet (SD) og Helse- og omsorgsdepartementet (HOD).
Denne rapporten beskriver produktene som er tilgjengelige på web-portalen http://www.luftkvalitet-nbv.no og dokumenterer metoder og data som er benyttet i utarbeidelsen av de ulike produktene. Rapporten beskriver også kort hvordan de ulike produktene bør brukes og peker på mulige anvendelser og begrensninger. Alle data på web-portalen er åpent tilgjengelig for alle og kan lastes ned til videre bruk.

On request from the Norwegian Environment Agency, a survey of atmospheric deposition of heavy metals around industrial enterprises in Norway has been carried out. The participation was voluntary and 22 industries located at 17 different sites financed their own participation. The survey is based on analysis of samples of naturally growing moss collected around the
enterprises during the summer of 2015 and includes 57 different elements. For a majority of the sites this survey is a followup of corresponding surveys carried out in 2000, 2005, and 2010. In general the results show that deposition of heavy metals close to the industries depends closely on the industrial processes used as well as the local topographic and meteorological conditions. The results are evaluated relative to corresponding background levels in moss in parts of Norway with low impact of air pollution. Like in previous surveys, the generally most polluted industrial location is Mo i Rana, followed by Odda. At most sites only minor general improvement is observed since the previous survey in 2010.
