A rise in HFC-23 emissions from eastern Asia since 2015
(Peer reviewed; Journal article, 2023)Trifluoromethane (CHF3, HFC-23), one of the most potent greenhouse gases among hydrofluorocarbons (HFCs), is mainly emitted to the atmosphere as a by-product in the production of the ozone-depleting legacy refrigerant and ... -
Arctic Tropospheric Ozone Trends
(Peer reviewed; Journal article, 2023)Observed trends in tropospheric ozone, an important air pollutant and short-lived climate forcer (SLCF), are estimated using available surface and ozonesonde profile data for 1993–2019, using a coherent methodology, and ... -
The atmospheric fate of 1,2-dibromo-4-(1,2-dibromoethyl)cyclohexane (TBECH): spatial patterns, seasonal variability, and deposition to Canadian coastal regions
(Peer reviewed; Journal article, 2023)Brominated flame retardants (BFRs) that are gradually being phased out are being replaced by emerging BFRs. Here, we report the concentration of the α- and β-isomers of 1,2-dibromo-4-(1,2-dibromoethyl)cyclohexane (TBECH; ... -
Linking Nanomaterial-Induced Mitochondrial Dysfunction to Existing Adverse Outcome Pathways for Chemicals
(Peer reviewed; Journal article, 2023)The Adverse Outcome Pathway (AOP) framework plays a crucial role in the paradigm shift of toxicity testing towards the development and use of new approach methodologies. AOPs developed for chemicals are in theory applicable ... -
Ingestion of car tire crumb rubber and uptake of associated chemicals by lumpfish (Cyclopterus lumpus)
(Peer reviewed; Journal article, 2023)Car tire rubber constitutes one of the largest fractions of microplastics emissions to the environment. The two main emission sources are tire wear particles (TWPs) formed through abrasion during driving and runoff of crumb ... -
The Composite Response of Traveling Planetary Waves in the Middle Atmosphere Surrounding Sudden Stratospheric Warmings through an Overreflection Perspective
(Peer reviewed; Journal article, 2023)Traveling planetary waves surrounding sudden stratospheric warming events can result from direct propagation from below or in situ generation. They can have significant impacts on the circulation in the mesosphere and lower ... -
Fluorine Mass Balance, including Total Fluorine, Extractable Organic Fluorine, Oxidizable Precursors, and Target Per- and Polyfluoroalkyl Substances, in Pooled Human Serum from the Tromsø Population in 1986, 2007, and 2015
(Peer reviewed; Journal article, 2023)Of the thousands of per- and polyfluoroalkyl substances (PFAS) known to exist, only a small fraction (≤1%) are commonly monitored in humans. This discrepancy has led to concerns that human exposure may be underestimated. ... -
Image-Text Connection: Exploring the Expansion of the Diversity Within Joint Feature Space Similarity Score
(Peer reviewed; Journal article, 2023)Cross-modal representation learning aims to learn a shared representation space where data from multiple modalities can be effectively compared, fused, and understood. This paper investigates the role of increased diversity ... -
Evaluation of meso- and microplastic ingestion by the northern fulmar through a non-lethal sampling method
(Peer reviewed; Journal article, 2023)An increasing number of organisms from the polar regions are reported contaminated by plastic. Rarely a non-killing sampling method is used. In this study we wanted to assess plastic levels using stomach flushing and ... -
Understanding the role of cities and citizen science in advancing sustainable development goals across Europe: insights from European research framework projects
(Peer reviewed; Journal article, 2023)This paper examines the potential impact of citizen science on achieving SDGs in cities. The analysis focuses on projects funded through the European Research Framework Programmes that utilize citizen science practices to ... -
Soil uptake of VOCs exceeds production when VOCs are readily available
(Peer reviewed; Journal article, 2023)Volatile organic compounds (VOCs) are reactive gaseous compounds with significant impacts on air quality and the Earth's radiative balance. While natural ecosystems are known to be major sources of VOCs, primarily due to ... -
Low-cost sensors and Machine Learning aid in identifying environmental factors affecting particulate matter emitted by household heating
(Peer reviewed; Journal article, 2023)Poland continues to rely heavily on coal and fossil fuels for household heating, despite efforts to reduce Particulate Matter (PM) levels. The availability of reliable air quality data is essential for policymakers, ... -
Semidiurnal nonmigrating tides in low-latitude lower thermospheric NO: A climatology based on 20 years of Odin/SMR measurements
(Peer reviewed; Journal article, 2023)The Sub-Millimetre Radiometer (SMR) on board the Odin satellite provides almost 20 years of nitric oxide (NO) measurements in the mesosphere and lower thermosphere (MLT) at equatorial crossing local solar times (LSTs) of ... -
Low-Processing Data Enrichment and Calibration for PM2.5 Low-Cost Sensors
(Peer reviewed; Journal article, 2023)Particulate matter (PM) in air has been proven to be hazardous to human health. Here we focused on analysis of PM data we obtained from the same campaign which was presented in our previous study. Multivariate linear and ... -
A roadmap to estimating agricultural ammonia volatilization over Europe using satellite observations and simulation data
(Peer reviewed; Journal article, 2023)Ammonia (NH3) is one of the most important gases emitted from agricultural practices. It affects air quality and the overall climate and is in turn influenced by long-term climate trends as well as by short-term fluctuations ... -
Modelling PCB-153 in northern ecosystems across time, space, and species using the nested exposure model
(Peer reviewed; Journal article, 2023)There is concern over possible effects on ecosystems and humans from exposure to persistent organic pollutants (POPs) and chemicals with similar properties. The main objective of this study was to develop, evaluate, and ... -
Increased contribution of biomass burning to haze events in Shanghai since China’s clean air actions
