Titanium Dioxide Nanoparticles Modulate Systemic Immune Response and Increase Levels of Reduced Glutathione in Mice after Seven-Week Inhalation
(Peer reviewed; Journal article, 2023)Titanium dioxide nanoparticles (TiO2 NPs) are used in a wide range of applications. Although inhalation of NPs is one of the most important toxicologically relevant routes, experimental studies on potential harmful effects ... -
Spatial variability and temporal changes of POPs in European background air
(Peer reviewed; Journal article, 2023)Concentration data on POPs in air is necessary to assess the effectiveness of international regulations aiming to reduce the emissions of persistent organic pollutants (POPs) into the environment. POPs in European background ... -
Plastic ingestion and associated additives in Faroe Islands chicks of the Northern Fulmar Fulmarus glacialis
(Peer reviewed; Journal article, 2022)Northern Fulmars (Fulmarus glacialis) are a pelagic seabird species distributed at northern and polar latitudes. They are often used as an indicator of plastic pollution in the North Sea region, but data are lacking from ... -
A flexible algorithm for network design based on information theory
(Peer reviewed; Journal article, 2023)A novel method for atmospheric network design is presented, which is based on information theory. The method does not require calculation of the posterior uncertainty (or uncertainty reduction) and is therefore computationally ... -
Global agricultural ammonia emissions simulated with the ORCHIDEE land surface mode
(Peer reviewed; Journal article, 2023)Ammonia (NH3) is an important atmospheric constituent. It plays a role in air quality and climate through the formation of ammonium sulfate and ammonium nitrate particles. It has also an impact on ecosystems through ... -
An optimised organic carbon∕elemental carbon (OC∕EC) fraction separation method for radiocarbon source apportionment applied to low-loaded Arctic aerosol filters
(Peer reviewed; Journal article, 2023)Radiocarbon (14C) analysis of carbonaceous aerosols is used for source apportionment, separating the carbon content into fossil vs. non-fossil origin, and is particularly useful when applied to subfractions of total carbon ... -
On coarse patterns in the atmospheric concentration of ice nucleating particles
(Peer reviewed; Journal article, 2023)The atmospheric concentration of ice nucleating particles active at around −10 °C (INP−10) is very low. Nevertheless, these particles play a role in the development of cloud systems, so their spatial and temporal patterns ... -
Environmental pollutants in the terrestrial and urban environment 2021. Revised report.
(NILU report;1/2023, Research report, 2023)Samples from the urban terrestrial environment in the Oslo area were analysed for metals and a large number of organic environmental pollutants. The selected samples that were analysed were soil, earthworm, fieldfare egg ... -
Sheath formation time for spherical Langmuir probes
(Peer reviewed; Journal article, 2023)The formation time of the surrounding sheath of Langmuir probes in an ionospheric plasma has been studied to better understand the constraints this puts on the sampling frequency of a probe. A fully kinetic three-dimensional ... -
CO2-rensing Klemetsrud. Beregning av nitros- og nitraminer.
(NILU rapport;11/2018, Research report, 2018)Beregning av spredning og dannelse av nitros- og nitramin er gjennomført for et potensielt aminbasert CO2-fangst-anlegg på Klemetsrud. Det er utført beregninger for tre ulike aminer. Beregningene viser makismal ... -
