European cities air quality ranking: a new methodology

Soares, Joana; Ortiz, Alberto González; Horálek, Jan; Schneider, Philipp; Schreiberova, Marketa

The EEA has introduced the European City Air Quality Viewer, a tool to assess and compare air quality in European cities. However, this method provides an incomplete picture of air quality as it relies solely on PM2.5 data from monitoring stations, excluding cities lacking monitoring stations and other relevant pollutants such as NO2 and O3. A promising alternative to the current methodology is proposed to reduce these limitations, offering a comprehensive approach to assessing and comparing health risks linked to exposure to multiple pollutants in urban settings. Leveraging continuous air quality maps and population-weighted concentrations enhances coverage and consistency in risk estimation across cities. Additionally, it allows for ranking based on multiple pollutants, unlike the current method, which focuses solely on PM2.5 levels. This approach integrates mortality risk assessments associated with PM2.5, NO2, and O3 exposure, aligning with the Environmental Burden of Disease assessments published by the ETC HE, together with the EEA.

Monitoring of the atmospheric ozone layer and natural ultraviolet radiation. Annual Report 2023

Svendby, Tove Marit; Fjæraa, Ann Mari; Schulze, Dorothea; Bäcklund, Are; Johnsen, Bjørn

This report summarizes the results from the Norwegian monitoring programme on stratospheric ozone and UV radiation measurements. The ozone layer has been measured at three locations since 1979: In Oslo/Kjeller, Tromsø/Andøya and Ny-Ålesund. The UV measurements started in 1995. The results show that there was a significant decrease in stratospheric ozone above Norway between 1979 and 1997. After that, the ozone layer stabilized at a level ~2% below pre-1980 level. The year 2023 was characterized by low ozone values in winter, high spring values, and annual average total ozone values slightly below the long-term mean.

Utslipp og spredning av støv fra LKAB i Narvik

Weydahl, Torleif; Grythe, Henrik; Vallejo, Islen; Markelj, Miha

Denne rapporten presenterer spredningsberegninger som estimerer LKAB sitt bidrag til forurensningssituasjonen i Narvik. Spredningsberegningene er basert på et anslag for det samlede støvutslippet fra både punktkilder og diffuse kilder via målt støvavsetning rundt anlegget. Spredningsberegningene som er utført med partikkelmodellen Flexpart-WRF, viser ingen overskridelse av grenseverdiene for PM10 eller PM2,5 utenfor LKABs industriområde.

Monitoring of long-range transported air pollutants in Norway. Annual report 2023.

Aas, Wenche; Eckhardt, Sabine; Evangeliou, Nikolaos; Hjellbrekke, Anne-Gunn; Platt, Stephen Matthew; Solberg, Sverre; Yttri, Karl Espen

This report presents results from the monitoring of atmospheric composition and deposition of air pollution in 2023, and focuses on main components in air and precipitation, particulate and gaseous phase of inorganic constituents, particulate carbonaceous matter, ground level ozone and particulate matter. The level of pollution in 2023 was generally low though a few episodes occurred. There was an increase in the PM levels in southern Norway during June, caused by a mixture of sources, including emissions from wildfires in Canada

Målinger av SO2 i omgivelsene til Elkem Carbon. Januar 2023 – desember 2023.

Hak, Claudia; Stensrød, Anna Maria Røyset; Andresen, Erik

På oppdrag fra Elkem Carbon AS har NILU utført målinger av SO2 i omgivelsene til Elkem Carbon i Vågsbygd (Kristiansand kommune). Målingene ble utført med SO2-monitor i boligområdet på Fiskåtangen (Konsul Wilds vei). I tillegg har Elkem Carbon AS valgt å måle med passive SO2-prøvetakere ved 3 steder rundt bedriften. Rapporten dekker målinger i perioden 1. januar – 31. desember 2023. Norske grenseverdier for luftkvalitet (SO2) ble overholdt ved Konsul Wilds vei for alle midlingsperioder (årsmiddel, vintermiddel, døgnmiddel og timemiddel). En døgnmiddelverdi var over nedre vurderingsterskel (50 µg/m3). Passive luftprøver viste at de mest belastede stedene i måleperioden var Konsul Wilds vei nordøst og Fiskåveien rett sør for bedriften.
