Environmental pollutants in the terrestrial and urban environment 2025
Samples from the urban terrestrial environment in the Oslo area were analysed for metals and a large number of organic environmental pollutants. The selected sample types that were analysed were sparrowhawk egg and liver samples of red fox and badger. Biomagnification potential was estimated based on detected data for relevant predator-prey pairs using data from year 2021 to 2025.

Måleprogram for tungmetallinnhold i støv og svevestøv i Rambergstua
NILU har kartlagt konsentrasjoner og kilder til tungmetaller i støv og luft i Rambergstua etter funn av høye blynivåer i 2025. Original rosemaling fra 1784 er hovedkilden, med høyt blyinnhold i hvit, rød og grønn maling, samt kvikksølv i rødfargen. Støvsugd støv inneholder fortsatt tungmetaller, men blynivået er vesentlig lavere enn i 2025. Svevestøv og kvikksølvgass ligger langt under Folkehelseinstituttets (FHI) helsebaserte luftkvalitetskriterier. Forvitret maling faller raskt til gulvet fremfor å holdes svevende.
Det konkluderes med at bygget er trygt å oppholde seg i. Det anbefales regelmessig støvsuging, opphør av bespisning, begrenset overflateberøring og god håndvask for å sikre et trygt innemiljø.

Forurensning i de norske havområdene - Barentshavet, Norskehavet og Nordsjøen
Denne rapporten fra Overvåkingsgruppen gir en oversikt over forurensningstilstanden i norske havområder. Overvåkingsgruppen har ansvar for 42 indikatorer med relevans for forurensning, publisert på miljostatus.no. Disse dekker blant annet lufttilførsler av miljøgifter og forurensning i sedimenter, forurensning i en rekke ulike marine arter, og tilførsler som skyldes aktiviteter i havområdene. Rapporten oppsummerer resultater fra indikatorene på miljostatus.no og fra andre publikasjoner om forurensning i de norske havområdene, for å gi en vurdering av hvordan ulike forurensende stoffer varierer med hensyn til bakgrunnsnivå, geografi, utvikling siste ti år, mattrygghet og mulige effekter på økosystemet. Som grunnlag for senere utvikling av egnede indikatorer for marin forsøpling, er det et eget kapittel som oppsummerer overvåkingen som finnes om marin forsøpling i Norge, både overvåking av mikroplast, strandsøppel, forsøpling i elver og søppel på havbunnen. Rapporten inneholder også et temakapittel om transportmodellering av miljøgifter som gir en oversikt over metoder for modellering samt hvordan disse kan brukes i miljøgiftovervåking.

Monitoring of environmental contaminants in freshwater food webs (MILFERSK), 2025
This report presents data from the fifth year of a five-year period for the MILFERSK program. In 2025, the monitoring program focused on the sampling and analysis of the pelagic food chain in Lake Mjøsa, encompassing the following sample types: zooplankton mainly epipelagic species, Mysis, vendace, E. smelt, and brown trout. Additionally, brown trout from the reference lake, Femunden, were collected. The concentrations of 228 individual compounds/isomers were determined, with frequent detections of specific per- and polyfluoroalkyl substances (PFAS), polybrominated diphenyl ethers (PBDEs), mercury (Hg), and siloxanes exhibiting biomagnifying properties throughout the food chain. Time series of these
contaminant groups show declining concentrations in brown trout in Lake Mjøsa. We also observe lower concentrations in the pelagic biota for phthalates and UVcompounds, compared to in 2023 when last pelagic biota was included in the program. Out of the 14 car tyre compounds included in the analysis of pelagic biota in 2025, only DPG and 6PPD Q were detected at low levels in zooplankton and Mysis.

Monitoring of the atmospheric ozone layer and natural ultraviolet radiation. Annual report 2025
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 2025 was characterized by low total ozone values most of the year, especially at Kjeller and Andøya, which contributed to high annual UV doses at these stations.

Environmental Contaminants in an Urban Fjord, 2025
This report presents data from the last year of a 5-year period of the Urban Fjord programme. The programme started in 2013 and has since been altered/advanced. In 2025 the programme covers sampling and analyses of sediment, polychaetes, krill, shrimps, blue mussels, herring, cod, eider, and herring gull from the Inner Oslofjord. A total of 230 single compounds/isomers were analysed, and frequent detection was found of specific PFAS compounds (e.g. PFOS) in most matrices, certain QACs in several matrices (ATAC-C22 in all
matrices), specific benzothiazoles in eider blood, LCCPs in certain matrices, certain siloxanes in most matrices, metals in all matrices and PCBs in all matrices. Biomagnification was observed for 24 PCB congeners, LCCPs and D4 (siloxane; lipid wt. basis). Furthermore, biomagnification was observed for PFOSA, ATAC-C20 and ATAC-C22, as well as for the metals As and Hg (wet wt. basis).

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.

NILU har, på vegne av Telemarksforskning og Norsk Folkemuseum, analysert miljøgifter i støv, luft og materialprøver fra utvalgte antikvariske bygg. Målet var å kartlegge nivåer av miljøgifter brukt i tidligere konserveringsarbeid. Studien omfattet analyser av tungmetaller, PAH og pesticider i støv fra ni bygninger, screening av VOC i luft, samt materialprøver fra tre bygninger. Resultatene viste bekymringsverdige nivåer av tungmetaller, PAH og pesticider i støv, og svært høye nivåer av PCP i to av tre materialprøver, til tross for lav totalmengde VOC.

The report provides the annual update of the European air quality concentration maps and population and vegetation exposure estimates for human health related indicators of pollutants PM10 (annual average, 90.4 percentile of daily means), PM2.5 (annual average), ozone (93.2 percentile of maximum daily 8-hour means, peak season average of maximum daily 8-hour means, SOMO35, SOMO10), NO2 (annual average) and benzo(a)pyrene (annual average), and vegetation related ozone indicators (AOT40 for vegetation and for forests) for the year 2023. The report contains also maps of Phytotoxic ozone dose (PODY) for selected crops (wheat, potato and tomato) and trees (spruce and beech) and NOx annual average map for the same year 2023. The trends in exposure estimates in the period 2005-2023 are summarized. The analysis for 2023 is based on the interpolation of the annual statistics of the 2023 observational data reported by the EEA member and cooperating countries and other voluntary reporting countries and stored in the Air Quality e-reporting database, complemented, when needed, with measurements from additional sources. The mapping method is the Regression – Interpolation – Merging Mapping (RIMM). It combines monitoring data, chemical transport model results and other supplementary data using linear regression model followed by kriging of its residuals (residual kriging). The report presents the mapping results and gives an uncertainty analysis of the interpolated maps. It also presents concentration change in 2023 in comparison to the 5-year average 2018-2022 using the difference maps and exposure estimates.

EEA´s revision of the European air quality index bands
The European Air quality index has been updated and now its bands take into consideration the World Health Organization global air quality guidelines, published in 2021. A subindex per pollutant is calculated based on hourly data (including for PM, for which running 24-hours averages were considered before) and on the risk of short-term mortality. The worst pollutant subindex categorizes the index. The health messages linked to the different index categories remain unchanged.

Monitoring air quality around airports and nearby cities is crucial to understanding the role of emissions from air traffic and other airport activities. This report analyses air quality in 23 European airports, revealing limited observations in and around airport areas. Only three of the 23 airports had at least one air quality sampling point for NO2, PM2.5 and O3 inside the airport area. Concentrations in nearby cities can be up to double (NO2), 57% higher (PM2.5) and 85% higher (O3) when the wind comes from the airport. EEA air quality maps showed higher annual mean NO2 concentrations in airport areas compared to surrounding regions, with one airport above the 2030 limit value of 20 µg/m³. Annual mean PM2.5 concentrations were also higher in airport areas, with six airports exceeding the revised limit value. The limited number of sampling points makes it challenging to assess trends in NO2, PM2.5 and O3 concentrations. A final chapter of the report presents an overview of available measurements and studies of ultra fine particles (UFP) in the vicinity of airports.
