Accumulation of polychlorinated biphenyls from contaminated sediment by Atlantic cod (Gadus morhua): Direct accumulation from resuspended sediment and dietary accumulation via the polychaete Nereis virens
(Journal article; Peer reviewed, 2012)Bioaccumulation of sediment‐associated polychlorinated biphenyls (PCBs) was examined in Atlantic cod (Gadus morhua) through direct diffusion from the sediment (via the water phase) and through the food chain (dietary ... -
Age and Synchronization of Daphnia magna Affect Sensitivity to Teflubenzuron in Acute Standardized Toxicity Tests
(Peer reviewed; Journal article, 2023)The standard Daphnia sp. acute toxicity test for assessing the adverse effects of chemicals on aquatic invertebrates stipulates the use of neonates that are ≤24 h old (hours post release [hpr]) at the start of the exposure. ... -
Alkylated Polycyclic Aromatic Compounds in Road Runoff Are an Environmental Risk and Should Be Included in Future Investigations
(Peer reviewed; Journal article, 2022)Polycyclic aromatic compounds (PACs) and metals are important contaminants in road runoff. Vital mitigation measures against aquatic contamination from road runoff include the use of sedimentation ponds. However, it has ... -
AOP Report: Inhibition of Chitin Synthase 1 Leading to Increased Mortality in Arthropods
(Peer reviewed; Journal article, 2021) -
AOP Report: Uncoupling of Oxidative Phosphorylation Leading to Growth Inhibition via Decreased Cell Proliferation
(Peer reviewed; Journal article, 2021)This report describes a novel adverse outcome pathway (AOP) on uncoupling of oxidative phosphorylation (OXPHOS) leading to growth inhibition via decreased adenosine triphosphate (ATP) pool and cell proliferation (AOPWiki, ... -
Benzoylurea pesticides used as veterinary medicines in aquaculture: Risks and developmental effects on nontarget crustaceans
(Journal article; Peer reviewed, 2015)Diflubenzuron and teflubenzuron are benzoylureas that are used in aquaculture to control sea lice. Flubenzurons have low toxicity to many marine species such as fish and algae but by their nature are likely to have significant ... -
Big Question to Developing Solutions: A Decade of Progress in the Development of Aquatic New Approach Methodologies from 2012 to 2022
(Peer reviewed; Journal article, 2023)In 2012, 20 key questions related to hazard and exposure assessment and environmental and health risks of pharmaceuticals and personal care products in the natural environment were identified. A decade later, this article ... -
Combined and interactive effects of global climate change and toxicants on populations and communities
(Journal article; Peer reviewed, 2013)Increased temperature and other environmental effects of global climate change (GCC) have documented impacts on many species (e.g., polar bears, amphibians, coral reefs) as well as on ecosystem processes and species ... -
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 ... -
Ecological Drivers of Mercury Bioaccumulation in Fish of a Subarctic Watercourse
(Peer reviewed; Journal article, 2023)Mercury (Hg) is a serious concern for aquatic ecosystems because it may biomagnify to harmful concentrations within food webs and consequently end up in humans that eat fish. However, the trophic transfer of mercury through ... -
Effect-Directed Analysis Based on Transthyretin Binding Activity of Per- and Polyfluoroalkyl Substances in a Contaminated Sediment Extract
(Peer reviewed; Journal article, 2023)Only a fraction of the total number of per- and polyfluoroalkyl substances (PFAS) are monitored on a routine basis using targeted chemical analyses. We report on an approach toward identifying bioactive substances in ... -
Effects of Polyester Fibers and Car Tire Particles on Freshwater Invertebrates
(Peer reviewed; Journal article, 2022)Microplastic ingestion has been shown for various organisms, but knowledge of the potential adverse effects on freshwater invertebrates remains limited. We assessed the ingestion capacity and the associated effects of ... -
Effects on Life-History Traits of Hypogastrura viatica (Collembola) Exposed to Imidacloprid Through Soil or Diet
(Peer reviewed; Journal article, 2021)Collembola (springtails) are important members of soil communities worldwide by contributing to degradation of organic matter. In nature, Collembola might be exposed to the neonicotinoid insecticide imidacloprid, which is ... -
In silico identification of chemicals capable of binding to the ecdysone receptor
(Peer reviewed; Journal article, 2020)The process of molting, known alternatively as ecdysis, is a feature integral in the life cycles of species across the arthropod phylum. Regulation occurs as a function of the interaction of ecdysteroid hormones with the ... -
Measurement of naphthenic acids in the receiving waters around an offshore oil platform by passive sampling
(Journal article; Peer reviewed, 2014)Polar organic chemical integrative samplers (POCIS) were deployed in the vicinity of an offshore oil installation and analyzed for naphthenic acids (NAs). The POCIS accumulated a range of mono‐ to tetracyclic NAs, with ... -
Methylmercury biomagnification in an Arctic pelagic food web
(Journal article; Peer reviewed, 2015)Mercury (Hg) is a toxic element that enters the biosphere from natural and anthropogenic sources, and emitted gaseous Hg enters the Arctic from lower latitudes by long-range transport. In aquatic systems, anoxic conditions ... -
