Nasjonalt samfunnsoppdrag om sirkulær økonomi. Forslag til organisering.
Denne rapporten inneholder forslag til organisering av et mulig nasjonalt samfunnsoppdrag om sirkulærøkonomien. Vårt forslag til organisering av et nasjonalt samfunnsoppdrag om sirkulær økonomi skiller seg noe fra eksisterende organisering av de to andre nasjonale samfunnsoppdragene i Norge i at den baserer seg på å etablere en omstillingslab. Omstillingslaben vil ha en rolle som likner på den «operativ gruppe» i de andre to nasjonale samfunnsoppdragene, men som er større i omfang, og har konkrete mål for oppfølgings- og medvirkningsprosesser mot målbar transformasjon.

Måling av gasser i Statsarkivets lokaler i Trondheim. Fase 2 - 2024
Denne rapporten viser resultater fra fase 2 i måleprosjektet NILU har utført ved Statsarkivet i Trondheim. Det er gjort prøvetaking og analyse i en periode på sju dager fra 23. til 30. mai ved to lokaliteter, én innendørs og én utendørs. Totalkonsentrasjonen av VOC’er (TVOC) ble målt til 135 µg/m3 gitt som toluen-ekvivalenter ved lokaliteten inne (MAG A, Reol 097) og 33 µg/m3 ved lokaliteten ute. Resultatene synliggjør effekten av innendørs ventilasjonssystemer og begge studiene vil brukes av Statsarkivet i sitt videre arbeid med innendørs luftkvalitet.

Assessing the environmental burden of disease related to air pollution in Europe in 2022
This report evaluates the health burden due to long-term exposure to PM2.5, NO2, and O3 across Europe in 2022. By analysing all-cause and cause-specific mortality and morbidity, it estimates disease burden using four indicators: Attributable Deaths (AD), Years of Life Lost, Years Lived with Disability, and Disability-Adjusted Life Years (DALY). However, the main results only consider the impact of exposure to levels of pollutants exceeding the current WHO air quality guidelines. The results indicate that PM2.5 contributes the most significant health impact (linked to six diseases), resulting in over 2.7 million DALY across 40 countries, and resulting in 269 000 AD, with mortality rates peaking in Eastern Europe. The report introduces methodological advancements, assessing the long-term impacts of O3 for the first time. Findings underscore the critical need for targeted air quality interventions, as pollution continues to drive significant health losses across the continent, particularly among vulnerable populations.

The report presents interim 2023 maps for PM10 annual average, PM2.5 annual average, O3 indicator peak season average of maximum daily 8-hour means, and NO2 annual average. The maps have been produced based on the 2023 non-validated E2a (UTD) data of the AQ e-reporting database, the CAMS Ensemble Forecast modelling data and other supplementary data. Together with the concentration maps, the inter-annual differences between 5-year average 2018-2022 and 2023 are presented (using the 2018-2022 regular and the 2023 interim maps), as well as basic exposure estimates based on the interim maps.

Analyses of selected organic contaminants and metals in coffee cups. Technical report.
On behalf of Norwegian Consumer Council, NILU has conducted analyses of organic contaminants and metals in the leachate from selected coffee-cups. The simulation of the leakage is conducted based on a compilation of the methods described within NS-EN-1186-9 and NS-EN-13130-1. The instrumental analytical methods used were already established at NILU and NIVA. A number of different organic contaminants and metals have been found in trace amounts in the different products.

Monitoring of long-range transported air pollutants in Norway. Annual report 2018.
This report presents results from the monitoring of atmospheric composition and deposition of air pollution in 2018, 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. 2018 was a special year with elevated ozone levels during the whole summer season due to prolonged heat and drought.

Air quality in Sandefjord, Norway. November 2021 – August 2023.
This report examines the air quality patterns in terms of particulate matter with a diameter less than 2.5 μm (PM2.5) in Sandefjord, Norway. PM2.5 was monitored through five low-cost sensors in hourly resolution from November 2021 to August 2023. The sensors’ reliability is high, with consistent PM2.5 measurements and similar variation over time. Occasional extreme PM2.5 was attributed to local contributions with higher values observed during cold months, or specific long-range transport events. Overall, Sandefjord maintained good air quality for most of the measurement period with daily PM2.5 levels below the air quality criteria. Residential heating activities (wood burning) is the most significant local source, being more pronounced during winter.

Survey of emissions of volatile organic chemicals from handheld toys for children above 3 years
NILU has, on behalf of the Norwegian Environment Agency, performed a screening study to identify volatile organic chemicals (VOCs) emitted from handheld toys for children. The goal was to identify individual VOCs emitted from toys at room temperature and to evaluate what impact the toys may have on the composition and concentrations of VOCs in indoor air. 12-30 individual VOCs were identified in each toy and 65-143 individual VOCs were detected with a concentration higher than 1 µg/m3. VOCs emitted at high concentrations and/or with hazardous properties were cyclohexanone, aromatic VOCs (xylenes, toluene, ethylbenzene), cyclic siloxanes and 2,2,4-Trimethyl-1,3-pentanediol diisobutyrate (TXIB). A regulated hydrochlorofluorocarbon (HCFC-141 b) was also detected from 5 toys. The toys with high concentrations of cyclohexanone and cyclic siloxanes affected the composition and concentrations of VOCs in indoor air.

Målinger av miljøgifter i luft ved Franzefoss Eide på Sotra og Husøya ved Kristiansund
NILU har gjennomført måleprogram for konsentrasjoner i luft ved Franzefoss Gjenvinning AS sine anlegg ved Eide på Sotra og ved Husøya ved Kristiansund. Ved Eide ble det tatt prøver i luft og analysert for prioriterte miljøgifter som dekloraner, fenoler, ftalater, PFAS, benzotriazoler, organiske tinnforbindelser, samt VOC inkludert D6, ammoniakk (NH3), gassfase HCl og hydrogensulfid (H2S). For de prioriterte miljøgiftene var de fleste prøvene under deteksjonsgrensen. De høyeste verdiene ble observert ved Lokasjon 11 Vannrenseanlegget. Ved Husøya ble det tatt prøver i luft og analysert for VOC inkludert D6, ammoniakk (NH3) og gassfase HCl. Verdiene ved Husøya var lavere enn ved Eide.

Air Quality in Ny-Ålesund. Monitoring of Local Air Quality 2019 and 2020.
The concentrations of the measured components are generally low and below national limit values for the protection of
human health and critical levels for the protection of vegetation. Wind from northern sectors gave the highest average concentrations of nitrogen oxides and sulfur dioxide, which indicates the power station and the harbour as possible sources. We also see single episodes of long-range transport of sulfur dioxide.

Screening of Chlorinated Paraffins, Dechloranes and UV-filters in Nordic Countries
In 2019, the Nordic screening group decided to perform a Nordic screening on chlorinated paraffins, dechloranes and UV-filters. These compounds are used in a wide range of applications. They all have long range transport characteristics and can potentially be regulated under the Stockholm POP convention. However, there are still huge data gaps, which need to be addressed in order to fulfill regulation requests. Several topics and questions were in focus for more measurements and a deeper understanding: (1) importance of long-range atmospheric transport and deposition, (2) differences/similarities in terrestrial versus marine food chains, and (3) variations between the Nordic countries and between urban and remote areas. Based on these priorities, availability of samples, and other practical reasons, samples from different Nordic countries, different environments, and both urban and remote places were selected. This study includes analysis of the compounds in air, marine and freshwater fish and marine mammals and bird eggs, but as the chlorinated paraffins also have been found to accumulate in the terrestrial food web, terrestrial mammals and bird eggs were included as well. Additionally, samples of pine needles were analysed both to look at the possibility for long range transport and to investigate it as a possible source of chlorinated paraffins for the terrestrial mammals.
