A case of anisotropic exchange of non-polar chemicals with absorption-based passive samplers in water
(Peer reviewed; Journal article, 2019)Passive sampling is a powerful technique for the sampling hydrophobic organic contaminants present at trace level in water. A robust application of performance reference compounds (PRCs) for the estimation of in situ ... -
Catchment properties and the photosynthetic trait composition of freshwater plant communities
(Peer reviewed; Journal article, 2019)Unlike in land plants, photosynthesis in many aquatic plants relies on bicarbonate in addition to carbon dioxide (CO2) to compensate for the low diffusivity and potential depletion of CO2 in water. Concentrations of ... -
Caught in the middle: bottom‑up and top‑down processes impacting recruitment in a small pelagic fsh
(Journal article; Peer reviewed, 2022)Understanding the drivers behind fluctuations in fish populations remains a key objective in fishery science. Our predictive capacity to explain these fluctuations is still relatively low, due to the amalgam of interacting ... -
CDOM absorption properties of natural water bodies along extreme environmental gradients
(Journal article; Peer reviewed, 2019)We present absorption properties of colored dissolved organic matter (CDOM) sampled in six different water bodies along extreme altitudinal, latitudinal, and trophic state gradients. Three sites are in Norway: the mesotrophic ... -
The challenges of opportunistic sampling when comparing prevalence of plastics in diving seabirds: A multi-species example from Norway
(Peer reviewed; Journal article, 2024)There is a need for baseline information about how much plastics are ingested by wildlife and potential negative consequences thereof. We analysed the frequency of occurrence (FO) of plastics >1 mm in the stomachs of five ... -
Challenges with Quantifying Tire Road Wear Particles: Recognizing the Need for Further Refinement of the ISO Technical Specification
(Peer reviewed; Journal article, 2021)Environmental monitoring data for tire road wear particles are vastly limited compared to those for other microplastics, primarily due to analytical challenges with quantification. Recently, two ISO technical specifications ... -
Changes in drug use in European cities during early COVID-19 lockdowns – A snapshot from wastewater analysis
(Peer reviewed; Journal article, 2021)The COVID-19 outbreak has forced countries to introduce severe restrictive measures to contain its spread. In particular, physical distancing and restriction of movement have had important consequences on human behaviour ... -
Changes in microbial water quality in RAS following altered feed loading
(Journal article; Peer reviewed, 2018)Intensive recirculating aquaculture systems (RAS) with its hyper-eutrophic water offer ideal conditions for bacterial growth, abundance and activity, potentially affecting fish and system performance. Feed composition and ... -
Changes in phytoplankton community structure over a century in relation to environmental factors
(Peer reviewed; Journal article, 2022)Changes in phytoplankton abundance and biomass during the period 1933–2020 were examined by statistical modeling using data from the Inner Oslofjorden phytoplankton database. The phytoplankton abundances increased with ... -
Changes in the diatom community in the great lake (Lurë National Park, Albania) from 2005 to 2017 and first steps towards assessment the water quality
(Peer reviewed; Journal article, 2020)Great Lake is the largest of 14 lakes situated in Lurë National Park, in the eastern part of the Lurë Mountains, Albania. To characterize lake ecological status, epiphytic and epilithic diatom samples were collected from ... -
Characterization of cell responses in Rhodomonas baltica exposed to PMMA nanoplastics
(Peer reviewed; Journal article, 2020)Due to their small size, nanoplastics (NPLs) possess specific properties which can potentiate their toxicity towards aquatic organisms. As primary producers, microalgae are at the base of aquatic food chains, thus negative ... -
Characterization of multiple biomarker responses using flow cytometry to improve environmental hazard assessment with the green microalgae Raphidocelis subcapitata
(Journal article; Peer reviewed, 2019)Microalgal toxicity tests using integrative endpoints as algal growth are regularly required to analyse the toxicity of potentially hazardous substances in the aquatic environment. However, these do not provide mechanistic ... -
Characterization of tire and road wear microplastic particle contamination in a road tunnel: From surface to release
(Peer reviewed; Journal article, 2022)Road pollution is one of the major sources of microplastic particles to the environment. The distribution of tire, polymer-modified bitumen (PMB) and tire and road wear particles (TRWP) in different tunnel compartments ... -
Characterizing combined effects of antiestrogenic chemicals on vitellogenin production in rainbow trout (Oncorhynchus mykiss) hepatocytes
(Journal article; Peer reviewed, 2017)Fish are exposed to a complex mixture of endocrine disrupting compounds (EDC), some of which display antiestrogenic activity leading to suppression of estrogen receptor (ER)- mediated reproductive processes. Although the ... -
Characterizing cytotoxic and estrogenic activity of Arctic char tissue extracts in primary Arctic char hepatocytes
(Journal article; Peer reviewed, 2017)Contaminants from various anthropogenic activities are detected in the Arctic due to long-range atmospheric transport, ocean currents, and living organisms such as migrating fish or seabirds. Although levels of persistent ... -
Charophytes in warm springs on Svalbard (Spitsbergen): DNA barcoding identifies Chara aspera and Chara canescens with unusual morphological traits
(Peer reviewed; Journal article, 2019)The Troll springs are warm springs on Svalbard (Spitsbergen). Charophytes were collected in the years 1910, 1912, 1958, 1992/1993, and 2018. However, since the Chara samples showed unusual morphological traits, there were ... -
Chasing equilibrium passive sampling of hydrophobic organic compounds in water
(Journal article; Peer reviewed, 2019)We investigated a combination of approaches to extend the attainment of partition equilibria between silicone passive samplers (samplers) and surface or treated waste water towards more hydrophobic organic compounds (HOC). ... -
China’s regulatory respond to plastic pollution: Trends and trajectories
(Peer reviewed; Journal article, 2022)Despite China having an international reputation as one of the largest contributors to plastic pollution in the world’s oceans, research analyzing China’s regulatory approach to governing plastic has been limited and ... -
Chitinase digestion for the analysis of microplastics in chitinaceous organisms using the terrestrial isopod Oniscus asellus L. as a model organism
(Peer reviewed; Journal article, 2021)Chitinaceous organisms have been found to ingest microplastic; however, a standardised, validated, and time- and cost-efficient method for dissolving these organisms without affecting microplastic particles is still required. ... -
