      Meltzer, Helle Margrete; Brandtzæg, Per; Knutsen, Helle Katrine; Løland, Beate Fossum; Odland, Jon Øyvind; Skåre, Janneche Utne; Torheim, Liv Elin; Amlund, Heidi; Arukwe, Augustine; Bernhoft, Aksel; Brantsæter, Anne Lise; Dierkes, Jutta; Eggesbø, Merete Åse; Eriksen, Gunnar Sundstøl; Frølich, Wenche; Frøyland, Livar; Fæste, Christiane Kruse; Halvorsen, Ragnhild; Haugen, Margaretha; Hemre, Gro Ingunn; Iversen, Per Ole; Krogdahl, Åshild; Lassen, Jørgen Fredrik; Lindemann, Rolf; Lyche, Jan Ludvig; Mansoor, Mohammad Azam; Nerland, Audun Helge; Næss, Bjørn; Ruus, Anders; Skålhegg, Bjørn Steen; Steffensen, Inger-Lise; Sundheim, Leif; Sverdrup, Line Emilie; Thomsen, Cathrine; Østerås, Olav; Alexander, Jan (Research report; Forskningsrapport, 2013-12-12)
      Breastmilk covers all the nutritional needs of the infant the first months of life, with the exception of vitamin D. In addition, breastmilk has a number of protective properties. However, as humans are exposed to polluting chemicals through food, air, water and skin contact, breastmilk also contains contaminants. Taking the present-day levels of contaminants in Norwegian breastmilk and the long ...

    • Description of the processes in the value chain and risk assessment of decomposition substances and oxidation products in fish Oils. Opinion of Steering Committee of the Norwegian Scientific Committee for Food Safety 

      Aursand, Marit; Hamre, Kristin; Knutsen, Helle Katrine; Maage, Amund; Arukwe, Augustine; Alexander, Jan; Amlund, Heidi; Bernhoft, Aksel; Brantsæter, Anne Lise; Eriksen, Gunnar Sundstøl; Fæste, Christiane Kruse; Krogdahl, Åshild; Haugen, Margaretha; Hemre, Gro Ingunn; Lassen, Jørgen Fr; Nerland, Audun Helge; Nesse, Live Lingaas; Næss, Bjørn; Ringø, Einar; Ruus, Anders; Skåre, Janneche Utne; Steffensen, Inger-Lise; Sundheim, Leif; Sverdrup, Line Emilie; Svihus, Birger; Thomsen, Cathrine; Torrissen, Ole; Østerås, Olav; Torstensen, Bente Elisabeth; Ørnsrud, Robin; Mozuraityte, Revilija (Research report; Forskningsrapport, 2011-10-19)
      The Norwegian Scientific Committee for Food Safety (VKM) has been asked by the Norwegian Food Safety Authority to perform a health risk assessment on decomposition substances and oxidation products in fish oils intended for human consumption except pharmaceuticals. Seal and/or krill oil intended for human consumption might be included but in separate chapters. EU’s hygiene regulations for the ...

    • Do DOM quality and origin affect the uptake and accumulation of lipid-soluble contaminants in coastal filter feeders? An experimental simulation of teflubenzuron exposure to blue mussels 

      Schultze, Sabrina; Andersen, Tom; Knudtzon, Nina Cathrine; Ruus, Anders; Rundberget, Jan Thomas; Brooks, Steven; Poste, Amanda Elizabeth; Hessen, Dag Olav; Borgå, Katrine (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-25)
      The increased export of terrestrial dissolved organic matter (terrDOM) to coastal marine ecosystems may affect local filter feeders and the local food web via the altered uptake of organic material and associated contaminants. To compare terrDOM to marine DOM (marDOM) as contaminant vectors to coastal biota, we exposed blue mussels (Mytilus sp.) to the different DOM types in combination with ...

    • Implications of Coastal Darkening for Contaminant Transport, Bioavailability, and Trophic Transfer in Northern Coastal Waters 

      McGovern, Maeve; Evenset, Anita; Borgå, Katrine; Wit, Heleen de; Braaten, Hans Fredrik Veiteberg; Hessen, Dag Olav; Schultze, Sabrina; Ruus, Anders; Poste, Amanda (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-13)
      The increased transport of terrestrially derived organic material (tOM) from catchments to rivers and lakes is leading to browning of northern freshwaters.(1) Although the same environmental drivers can be expected to lead to widespread increases in tOM and subsequent darkening in adjacent coastal systems,(2) this has received considerably less attention, and long-term monitoring data for detecting ...

    • Is Glacial Meltwater a Secondary Source of Legacy Contaminants to Arctic Coastal Food Webs? 

      Mcgovern, Maeve; Warner, Nicholas Alexander; Borgå, Katrine; Evenset, Anita; Carlsson, Pernilla Marianne; Skogsberg, Stina Linnea Emelie; Søreide, Janne; Ruus, Anders; Christensen, Guttorm; Poste, Amanda (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-26)
      Climate change-driven increases in air and sea temperatures are rapidly thawing the Arctic cryosphere with potential for remobilization and accumulation of legacy persistent organic pollutants (POPs) in adjacent coastal food webs. Here, we present concentrations of selected POPs in zooplankton (spatially and seasonally), as well as zoobenthos and sculpin (spatially) from Isfjorden, Svalbard. ...

    • Land-cover, climate and fjord morphology drive differences in organic matter and nutrient dynamics in two contrasting northern river-fjord systems 

      Schultze, Sabrina; Andersen, Tom; Hessen, Dag Olav; Ruus, Anders; Borgå, Katrine; Poste, Amanda (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-31)
      Climate and land-use changes are leading to impacts on individual ecosystems as well as shifts in transfer dynamics between interconnected systems. At the land-ocean interface, changes in riverine inputs of organic matter (OM) and nutrients have the potential to lead to shifts in coastal carbon and nutrient cycling with consequences for ecosystem structure and function. In this study, we assess OM ...

    • Methylmercury biomagnification in an Arctic pelagic food web 

      Ruus, Anders; Øverjordet, Ida Beathe; Braaten, Hans Fredrik Veiteberg; Evenset, Anita; Christensen, Guttorm N.; Heimstad, Eldbjørg Sofie; Gabrielsen, Geir W.; Borgå, Katrine (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-14)
      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 favor the bacterial transformation of inorganic Hg to methylmercury (MeHg), which has a greater potential for bioaccumulation than inorganic Hg and is the most toxic form of Hg. ...

    • Quantitative fatty acid signature analysis reveals a high level of dietary specialization in killer whales across the North Atlantic 

      Remili, Anaïs; Dietz, Rune; Sonne, Christian; Samarra, Filipa I. P.; Rikardsen, Audun H.; Kettemer, Lisa Elena; Ferguson, Steven H.; Watt, Cortney A.; Matthews, Cory J. D.; Kiszka, Jeremy J.; Jourdain, Eve Marie; Borgå, Katrine; Ruus, Anders; Granquist, Sandra M.; Rosing-Asvid, Aqqalu; McKinney, Melissa A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-13)
      Quantifying the diet composition of apex marine predators such as killer whales (Orcinus orca) is critical to assessing their food web impacts. Yet, with few exceptions, the feeding ecology of these apex predators remains poorly understood. <p>Here, we use our newly validated quantitative fatty acid signature analysis (QFASA) approach on nearly 200 killer whales and over 900 potential prey to model ...

    • Small Arctic rivers transport legacy contaminants from thawing catchments to coastal areas in Kongsfjorden, Svalbard 

      Mcgovern, Maeve; Borgå, Katrine; Heimstad, Eldbjørg Sofie; Ruus, Anders; Christensen, Guttorm; Evenset, Anita (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-29)
      Decades of atmospheric and oceanic long-range transport from lower latitudes have resulted in deposition and storage of persistent organic pollutants (POPs) in Arctic regions. With increased temperatures, melting glaciers and thawing permafrost may serve as a secondary source of these stored POPs to freshwater and marine ecosystems. Here, we present concentrations and composition of legacy POPs in ...
