Air Quality Plans and Measures. Analysis of data submitted from 2014 to 2020.
The submitted data were analysed with the aim to provide information to the EEA Member countries that can be used to improve their air quality management practices, and to give feedback on data quality and possible use. Previous studies in the framework of the Air Implementation Pilot (published in 2012 and 2013) made assessments of the measures and management practices but were not successful in defining the measures’ effectiveness, so the present report also looks into what kind of information can be obtained from the data.
In the period 2014 – 2020, 23 EEA member countries submitted at least one air quality plan. Most countries focus their plans on pollutants related to traffic: NO2 and/or PM10. Most measures target exceedances of NO2 (62 %), PM10 (26 %) and PM2.5 (10 %), and measures are reported that target exceedances of standards of benzo(a)pyrene, nickel and lead (all in PM10) as well as SO2. In one case, the measure is related to benzene.
« Traffic » is the main sector leading to exceedances, with 64 % of records, followed by « domestic heating » (14 %), « local industry » (10 %) and “Other” (8 %). The « Other » category when given further information could comprise a variety of sources including meteorology, agricultural residue burning, harbour activity or shipping.
The majority of the exceedances occurred in urban areas (65 %) followed by suburban areas (21 %), while 14 % of the exceedances addressed in the plans occurred in rural areas.
The available data consist of a large number of individual records (ranging from several hundreds to over 20 thousand depending on the reporting element) that in theory can be linked using unique identifiers. However, not all the records can be linked. While the basis for analysis can vary depending on which reporting segments are used, the overall results are consistent across the segments, and provide a very good overview of which air pollution abatement measures are taken by national and local authorities.

Air quality European-wide annual maps based on the Air Quality (AQ) e-Reporting validated (E1a) measurement data, the EMEP modelling data and other supplementary data have been regularly produced, using the Regression – Interpolation – Merging Mapping (RIMM) methodology. However, due to the time schedule of production of the validated AQ measurement and the EMEP modelling data, the RIMM air quality maps of a year Y have typically not been available until May of year Y+2. In this report, we examine the AQ interim mapping, based on the preliminary (E2a) measurement and the CAMS Ensemble Forecast modelling data. Such interim maps could be prepared one year earlier than the validated maps. In order to overcome an obstacle of data gaps of E2a data in several areas, so-called pseudo stations data in areas with no E2a data are estimated, based on regression relation between E2a data from year Y and validated E1a data from year Y-1, together with the ratio of the modelling results from years Y and Y-1. The analysis have been performed for the PM10 annual average, the NO2 annual average and the ozone indicator SOMO35, based on the 2017 data. We evaluate these maps using the validated E1a data. Based on the results, we recommend the regular production of the interim AQ maps for the examined indicators, in addition to the regular AQ maps.

Luftkvalitet i Ny-Ålesund. Målinger av lokal luftkvalitet 2019 og 2020.
De målte konsentrasjonene var generelt lave for alle komponenter og under nasjonale grenseverdier for beskyttelse av menneskets helse og økosystemet. Vind fra nordlige sektorer ga de høyeste gjennomsnittskonsentrasjonene av nitrogenoksider og svoveldioksid, noe som peker på kraftstasjonen og havnen som mulige kilder. Vi ser også enkelte episoder med langtransport av svoveldioksid.

NILU – Norsk institutt for luftforskning og Ingenia AS har på oppdrag fra Statens vegvesen kartlagt effekten ventilasjonstårnene i Ekeberg- og Bjørvikatunnelen har med hensyn til å redusere luftforurensning fra dagsonen på Sørenga. Prosjektet besto av et omfangsrikt måleprogram i og rundt Operatunnelen i Bjørvika, en vurdering av ventilasjonstårnenes effekt basert på målingene og forslag til prinsipper for et nytt styringsregime.
Drift av ventilasjonstårnene ble funnet å ha en tydelig effekt på PM10- og NO2-konsentrasjonen i dagsonen og på bakkenivå utenfor dagsonen fra trinn 3 (av 4). Forslaget til nytt styringsregime fokuserer på ventilasjonstårndrift i piggdekksesongen og avhengighet av ytre forhold.

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.

Monitoring of greenhouse gases and aerosols at Svalbard and Birkenes in 2020. Annual report.
The report summarizes the activities and results of the greenhouse gas monitoring at the Zeppelin Observatory, situated on Svalbard in Arctic Norway, during the period 2001-2020, and the greenhouse gas monitoring and aerosol observations from Birkenes for 2009-2020.
