Impact of 3D cloud structures on the atmospheric trace gas products from UV–Vis sounders – Part 2: Impact on NO2 retrieval and mitigation strategies
(Journal article, 2022)Operational retrievals of tropospheric trace gases from space-borne spectrometers are based on one-dimensional radiative transfer models. To minimize cloud effects, trace gas retrievals generally implement a simple cloud ... -
Integument carotenoid-based colouration reflects contamination to perfluoroalkyl substances, but not mercury, in arctic black-legged kittiwakes
(Peer reviewed; Journal article, 2022)Anthropogenic activities are introducing multiple chemical contaminants into ecosystems that act as stressors for wildlife. Perfluoroalkyl substances (PFAS) and mercury (Hg) are two relevant contaminants that may cause ... -
Decitabine-induced DNA methylation-mediated transcriptomic reprogramming in human breast cancer cell lines; the impact of DCK overexpression
(Peer reviewed; Journal article, 2022)Decitabine (DAC), a DNA methyltransferase (DNMT) inhibitor, is tested in combination with conventional anticancer drugs as a treatment option for various solid tumors. Although epigenome modulation provides a promising ... -
Differences in Trophic Level, Contaminant Load, and DNA Damage in an Urban and a Remote Herring Gull (Larus argentatus) Breeding Colony in Coastal Norway
(Peer reviewed; Journal article, 2022)Herring gulls (Larus argentatus) are opportunistic feeders, resulting in contaminant exposure depending on area and habitat. We compared contaminant concentrations and dietary markers between two herring gull breeding ... -
Comparison of young male mice of two different strains (C57BL/6J and the hybrid B6129SF1/J) in selected behavior tests. A small scale study
(Peer reviewed; Journal article, 2022)BACKGROUND All mouse strains are different, before choosing a strain for a large study, a small scale study should be done. In this study, we compared young males of two mouse strains, C57BL/6J and the hybrid B6129SF1/J, ... -
Comparisons between the distributions of dust and combustion aerosols in MERRA-2, FLEXPART, and CALIPSO and implications for deposition freezing over wintertime Siberia
(Peer reviewed; Journal article, 2022)Aerosol distributions have a potentially large influence on climate-relevant cloud properties but can be difficult to observe over the Arctic given pervasive cloudiness, long polar nights, data paucity over remote regions, ... -
Clean air policies are key for successfully mitigating Arctic warming
(Peer reviewed; Journal article, 2022)A tighter integration of modeling frameworks for climate and air quality is urgently needed to assess the impacts of clean air policies on future Arctic and global climate. We combined a new model emulator and comprehensive ... -
Lack of mutagenicity of TiO2 nanoparticles in vitro despite cellular and nuclear uptake
(Peer reviewed; Journal article, 2022)The potential genotoxicity of titanium dioxide (TiO2) nanoparticles (NPs) is a conflictive topic because both positive and negative findings have been reported. To add clarity, we have carried out a study with two cell ... -
Impact of the Pacific sector sea ice loss on the sudden stratospheric warming characteristics
(Peer reviewed; Journal article, 2022)The atmospheric response to Arctic sea ice loss remains a subject of much debate. Most studies have focused on the sea ice retreat in the Barents-Kara Seas and its troposphere-stratosphere influence. Here, we investigate ... -
Norges målenettverk for luftkvalitet. Gjennomgang av stasjonsplasseringer i forhold til krav i EUs luftkvalitetsdirektiver.
(NILU rapport;23/2022, Research report, 2022)Rapporten gir en oversikt over Norges luftkvalitetsmålenettverk. Alle målestasjoner som rapporterer måledata til EEA/ESA er beskrevet og plasseringen er vurdert i forhold til krav i EUs direktiver. Omgivelsene til stasjonene ... -
The colony forming efficiency assay for toxicity testing of nanomaterials – Modifications for higher-throughput
(Peer reviewed; Journal article, 2022)To cope with the high number of nanomaterials manufactured, it is essential to develop high-throughput methods for in vitro toxicity screening. At the same time, the issue with interference of the nanomaterial (NM) with ... -
A multi-pollutant and multi-sectorial approach to screening the consistency of emission inventories
(Peer reviewed; Journal article, 2022)Some studies show that significant uncertainties affect emission inventories, which may impeach conclusions based on air-quality model results. These uncertainties result from the need to compile a wide variety of information ... -
Thallium Pollution in Europe Over the Twentieth Century Recorded in Alpine Ice: Contributions From Coal Burning and Cement Production
(Peer reviewed; Journal article, 2022)Emission inventories indicate that thallium, a highly toxic metal, is emitted during coal burning and cement production. These estimates have been established only for the 1980s and 1990s but up to now they have not been ... -
