Suspect screening helps detect chemicals in environmental samples without predefined target lists which can facilitate isolation of a larger number of substances. This study shows however that no single extraction method or analytical platform (LC-HRMS or GC-HRMS) can capture all relevant pollutants—at least half are missed. The technique works best for chemically similar families, where optimized methods can target specific classes or broader families of similar substances (e.g. PFAS). Effective grouping of similar substances is therefore essential. A broad coverage of substances can however be achieved if multiple sample extractions are performed and each extract is analysed on both LC- and GC-HRMS. Strategies where comparisons can be made over time or across locations will also help to isolate pollutant-related signals from the background. Such considerations must be integrated into programme design and budgeting for retrospective analysis. This will maximize likelihood of detection for the largest diversity of substances.

MIKRONOR 2024 Monitoring of microplastics and tyre wear particles in the Norwegian environment
The 2024 MIKRONOR campaign, coordinated by NIVA and NILU on behalf of the Norwegian Environment Agency, signifcantly expanded the national monitoring framework for microplastics (MPs) to encompass diverse environmental compartments, including surface waters (Oslofjord and Lake Mjøsa), urban runoff, marine sediments, atmospheric deposition, and coastal beach sediments. Urban stormwater runoff was identifed as a predominant source of MPs, particularly tyre wear particles (TWP). Sediment samples from stormwater traps in Oslo exhibited high TWP concentrations up to 240 mg/g, constituting approximately 25% of the total sediment mass. Corresponding runoff water samples revealed MP concentrations as high as 733 ± 142 particles/L, indicating substantial episodic fuxes of MPs into receiving aquatic or marine systems. Inner Oslofjord sediments contained 0.6–3.5 % TWP by mass, confrming the high levels found in 2023. Microplastic concentrations in surface waters were generally low, ranging from 0 to 0.6 MP/m³. However, two hydrodynamic accumulation zones within the Oslofjord exhibited anomalously high concentrations, with levels approximately two orders of magnitude greater than outside the accumulation zones. One net tow recovered >7,000 fragments of expanded polystyrene, highlighting localized retention. Atmospheric deposition peaked in urban Sofenbergparken (1514 µg/m²/d; 68 % TWP) and showed a clear urban-to-remote gradient. Beach sediments at Akerøya remained low in MPs, with most samples below detection limits. The findings highlight urban runoff, especially TWP, as a dominant source to the Oslofjord, and reveal critical hotspots in both water and air pathways.

National E-waste Monitor 2025 - Norway
The National E-waste Monitor 2025 – Norway provides a detailed assessment of the current situation of e-waste statistics and legislation, and an outlook on e-waste statistics up to 2050.
Norway is the world’s leading nation in Waste Electrical and Electronic Equipment (WEEE) generation per capita, producing 27.5 kg per person in 2022, equivalent to 149 kt.
However, the country has established an efficient collection system, successfully gathering 72% of generated e-waste, with 107 kt tons collected in 2022 (approximately 19.5 kg per capita).
The country’s WEEE stock has seen significant growth over the past decade, expanding from 14 million tons in 2010 to nearly 20 million tons in 2022. However, based on the monitor’s results, the implementation of robust Circular Economy measures could help EEE Put on the Market in Norway reaching, by 2050, half of the to 2010 levels (67 kt). The big drop is explained by more repairability and improved durability of EEE products; by contrast, the projection in a Business as Usual scenario would be 5 times higher (294 kt) than in the Circular Economy scenario.
In terms of international trade, Norway reported 20 kt of used EEE exports for reuse, primarily within the European Union. Legal WEEE exports saw an increase from 27 kt in 2022 to 38 kt in 2023. Authorities intercepted 15.5 t of illegal exports due to inadequate documentation and functionality testing.
Upcoming country investments may go in the direction of recycling technologies for rare earth metals and precious materials recovery, improved small electronics collection systems, stricter labelling requirements for recyclable components and hazardous substances.
While Norway’s e-waste management system is already considered exemplary, the monitor’s results emphasize the need for more ambitious targets aligned with the WEEE Directive to create a truly sustainable and circular electronics management system. The focus is now shifting toward public awareness campaigns to encourage repair over replacement and the development of more efficient collection methods for small electronic devices.

Assessing the environmental burden of disease related to air pollution in Europe in 2023
This report evaluates the environmental burden of disease (EBD) linked to long-term exposure to fine particulate matter (PM2.5), nitrogen dioxide (NO2), and ozone (O3) across 41 European countries in 2023. Using the key health indicators—attributable deaths, years of life lost, years lived with disability, and disability-adjusted life years—the analysis quantifies the health impacts of air pollution above concentrations defined as the World Health Organisation’s air quality guideline levels. Approximately 206,000 deaths are attributable to PM2.5, while about 56,000 and 71,000 deaths area attributable to NO2 and O3, respectively. The disease burden from PM2.5 was highest due to its association with multiple health outcomes, with high baseline prevalence and mortality. Results highlight strong regional disparities, with South-Eastern Europe most affected by health effects from PM2.5 and NO2, and Southern Europe by those from O3. Findings underscore the need for targeted policies to reduce pollutant-specific health impacts in Europe.

Denne rapporten beskriver en studie utført av NILU for Nordre Follo kommune, med støtte fra Folkehelseinstituttet. Målet var å prøve uhildet kartlegging som metode for å undersøke hvilke organisk-kjemiske forbindelser som finnes i nedbørfeltet til drikkevannskilden Gjersjøen. Som del av dette ønsket vi også å identifisere forbindelser som forårsaker feilaktige, store utslag i nitratsensorer. Ved bruk av høyoppløselig massespektrometri og miljøforensiske metoder ble 163 markører identifisert, inkludert aspirin, kreatin og kreatinin, knyttet til kloakkforurensning under kraftig nedbør. Funnene gir innsikt i kjemisk interferens og kan forbedre overvåkingssystemer og vannforvaltning.

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.

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.

Environmental Contaminants in an Urban Fjord, 2024 – Emphasis on Alna River
This report presents data from the fourth year of a 5-year period of the Urban Fjord
programme. The programme started in 2013 and has since been altered/advanced.
In 2024 the programme covers sampling and analyses of water, water moss,
invertebrates, and trout from Alna River, as well as stormwater from Eastern Oslo
City. A sampling campaign was also conducted for source tracing of chlorhexidine,
dichloromethane and trichloromethane previously found in Alna River. A total of
240 single compounds/isomers were analyzed, and frequent detection was found
of specifc PFAS compounds in aqueous phases, other specifc PFAS compounds in
trout liver, UV-compounds and certain QACs in the particulate fraction of
stormwater, certain benzothiazoles in stormwater (dissolved and/or particulate
fraction) , chlorinated paraffns (MCCP and LCCP) in biota, certain siloxanes in
nearly all matrices, metals in all matrices, and PCBs in biota. Biomagnifcation was
only observed for a couple of the PCB congeners. However, as expected,
biomagnifcation was observed for mercury and PFOS. Biomagnifcation of silver
was observed when trout was represented by liver samples, but not muscle samples.
The source tracing showed the presence of the compounds at several stations

NILU har på oppdrag fra Hydro Aluminium AS Årdal Metallverk utført målinger av svevestøv (PM2.5, PM10), arsen (As), nikkel (Ni) og gassformig fluorid (HF) i omgivelsesluft i Øvre Årdal. Målingene pågikk i perioden 12. januar 2024 – 2. januar 2025 ved Årdal VGS. Konsentrasjonene av de målte komponentene var under de individuelle grenseverdier, målsettingsverdier og luftkvalitetskriterier i måleperioden. Vurderinger rundt spredningsberegningene fra 2021 og måleresultatene fra 2024 viser godt samsvar mellom beregninger og målinger for As, mens beregnet Ni er overestimert sammenlignet med målingene. For svevestøv er beregningene i finfraksjonen PM2.5 litt underestimert sammenlignet med målingene, for PM10 samsvarer beregningene godt med hva som er målt.
