NO2-måling i omgivelsene til Eramet Sauda
På oppdrag fra Eramet Sauda AS har NILU utført målinger av NO2 i omgivelsene til smelteverket i Sauda. Målingene ble utført med NOx-monitor ved Birkelandsvegen nordøst for bedriften. I tillegg ble NO2 målt med passive prøvetakere ved 3 steder i Sauda. Måleperioden varte fra 30. august 2024 til 10. mars 2025. Norske grenseverdier for luftkvalitet (NO2) og luftkvalitetskriterier ble overholdt ved Birkelandsvegen for alle midlingsperioder. Formålet med prosjektet var å vurdere effekten av det nye energigjenvinningsanlegget (bestående av 7 gassmotorer) på NO2 konsentrasjonen. Det ble ikke funnet noen sammenheng mellom vindretning fra sør-sørvest (fra bedriften mot målestasjonen), motordrift og NO2 konsentrasjonene målt ved måleboden.

This report documents the EMEP VOC monitoring carried out in 2023. The levels of the measured species in 2023 are presented as well as the 2023-status and history of the VOC programme. The geographical pattern of the species in Europe is discussed as well as the long-term trend during the last 20 years.

Screening Program 2024. Substances in electronic waste facilities and wastewater treatment
The 2024 Screening Programme investigated emerging and legacy contaminants in e-waste facilities and wastewater treatment. LCD substances, flame retardants, plasticizers, and their metabolites were found in air, dust, and water near e-waste sites. Bisphenol-related compounds and follow-up substances were detected in wastewater, particularly in sludge and particles. The findings highlight environmental dispersion, treatment efficiency, and the need for continued monitoring.

Assessing the siting of air quality sampling points at industrial sites
Air quality measurements at industrial locations are intended to assess emission sources typically of the largest magnitude, many of which operate over a long time and are subject to specific permitting rules. Industrial sources represent a significant contribution to the air pollution that people and ecosystems are exposed to. Therefore, appropriately sited sampling points are essential to understanding the characteristics of these emissions, which is necessary to design meaningful monitoring network, implement effective abatement strategies, and inform supplementary assessment methods such as dispersion modelling. Existing environmental legislation establishes criteria for the reporting of industrial emissions and for the design of monitoring networks on pollutant concentrations: 1) the Industrial Emissions Directive (IED), 2) the Regulation on European Pollutant Release and Transfer Register (E-PRTR), and 3) the Ambient Air Quality Directives (AAQDs, Directives 2008/50/EC and 2004/107/EC, as well as the Revised Directive (EU) 2024/2881). The AAQDs provide rules and guidance for monitoring stations across different environments, including specific rules for those classified as industrial. In this study we have evaluated the air quality monitoring sampling points associated with industrial sources. The overarching aim is to underpin assessments by the European Commission of whether the criteria for placing industrial sampling points are applied throughout the European Union in a harmonised manner and whether the application of the criteria ensures that the highest exposure of the general population to air pollution from industrial sources is measured in all air quality zones. For this reason, we have carried out an evaluation of the 2019 monitoring network across Europe in the vicinity of industrial sources.

Melkøya ferskvann, nedbør, vegetasjon og jord 2024
I 2024 var det igjen tid for den tradisjonelle overvåkningen av ferskvann. I forbindelse med endringer i produksjonen og mulige økte utslipp av kvikksølv ble det gjort enkelte endringer i programmet for ferskvann samtidig som det ble iverksatt undersøkelser av kvikksølv (Hg), bly (Pb) og polysykliske aromatiske hydrokarboner (PAH) i nedbør, vegetasjon og jord. I det nye programmet er det god samlokalisering mellom prøvetakingsstasjoner for ferskvann, nedbør, vegetasjon og jordprøver.
Det ble gjennomført innsamling av prøver i ferskvann, nedbør, vegetasjon og jord fra starten av september.

Monitoring of the atmospheric ozone layer and natural ultraviolet radiation. Annual report 2024
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 2024 was characterized by high total ozone values most of the year, especially in the Arctic stations in March. For Ny-Ålesund, 2024 showed the highest annual average total ozone value since systematic ground-based ozone measurements started in 1997.
