Bioaccumulation of trace elements in liver and kidney of fish species from three freshwater lakes in the Ethiopian Rift Valley
Masresha, Alemayehu Esayas; Skipperud, Lindis; Rosseland, Bjørn Olav; Gebremariam, Zinabu; Meland, Sondre; Salbu, Brit (Peer reviewed; Journal article, 2021)The objective of the present work was to obtain scientific information on the ecological health of three freshwater lakes (Awassa, Koka, and Ziway) situated in the Ethiopian Rift Valley by investigating possible trace ... -
Dose-dependent hepatic transcriptional responses in Atlantic salmon (Salmo salar) exposed to sublethal doses of gamma radiation
Song, You; Salbu, Brit; Teien, Hans-Christian; Heier, Lene Sørlie; Rosseland, Bjørn Olav; Tollefsen, Knut-Erik (Journal article; Peer reviewed, 2014)Due to the production of free radicals, gamma radiation may pose a hazard to living organisms. The high-dose radiation effects have been extensively studied, whereas the ecotoxicity data on low-dose gamma radiation is still ... -
Global transcriptional analysis of short-term hepatic stress responses in Atlantic salmon (Salmo salar) exposed to depleted uranium
Song, You; Salbu, Brit; Teien, Hans-Christian; Heier, Lene Sørlie; Rosseland, Bjørn Olav; Høgåsen, Tore; Tollefsen, Knut-Erik (Journal article; Peer reviewed, 2014)Potential environmental hazards of radionuclides are often studied at the individual level. Sufficient toxicogenomics data at the molecular/cellular level for understanding the effects and modes of toxic action (MoAs) of ... -
Hepatic transcriptional responses in Atlantic salmon (Salmo salar) exposed to gamma radiation and depleted uranium singly and in combination
Song, You; Salbu, Brit; Teien, Hans-Christian; Evensen, Øystein; Lind, Ole Christian; Rosseland, Bjørn Olav; Tollefsen, Knut Erik (Journal article; Peer reviewed, 2016)Radionuclides are a special group of substances posing both radiological and chemical hazards to organisms. As a preliminary approach to understand the combined effects of radionuclides, exposure studies were designed using ... -
Hepatic transcriptomic profiling reveals early toxicological mechanisms of uranium in Atlantic salmon (Salmo salar)
Song, You; Salbu, Brit; Teien, Hans-Christian; Heier, Lene Sørlie; Rosseland, Bjørn Olav; Høgåsen, Tore; Tollefsen, Knut-Erik (Journal article; Peer reviewed, 2014) -
Introduced European minnow Phoxinus phoxinus in alpine lakes may increase total mercury concentration in brown trout Salmo trutta
Borgstrøm, Reidar; Rognerud, Sigurd; Meland, Sondre; Rosseland, Bjørn Olav (Peer reviewed; Journal article, 2021)In Norway, the cyprinid European minnow Phoxinus phoxinus has been spread far outside its previous natural distribution area, with lots of establishments in mountain lakes where brown trout Salmo trutta originally was the ... -
Påvirkes laksesmolt av aluminium i brakkvann?Telemetriundersøkelser i Storelva i Holt, Aust-Agder,2007
Kroglund, Frode; Høgberget, Rolf; Haraldstad, Tormod; Økland, Finn; Thorstad, Eva Bonsak; Teien, Hans-Christian; Rosseland, Bjørn Olav; Salbu, Brit; Nilsen, Tom Ole; Stefansson, Sigurd Olav; Guttrup, Jim (NIVA-rapport;6245, Research report, 2011)Storelva har vært fullkalket siden 1996. Kalkingen har ikke gitt den forventede økningen i fangst av laks. Vassdraget avviker således fra erfaringene man har fra andre kalka elver på Sørlandet. Flere hypoteser er ... -
Påvirkes laksesmolt av aluminium i brakkvann?Telemtriundersøkelser Storelva i Holt, Aust-Agder,2008
Kroglund, Frode; Høgberget, Rolf; Haraldstad, Tormod; Økland, Finn; Thorstad, Eva Bonsak; Teien, Hans-Christian; Rosseland, Bjørn Olav; Salbu, Brit; Nilsen, Tom Ole; Stefansson, Sigurd Olav; Guttrup, Jim (NIVA-rapport;6246, Research report, 2011)Fangsten av laks i Storelva i Holt er lavere enn forventet. Flere hypoteser er forkastet. De senere årene har fokus vært på: vil aluminium i brakkvann kunne hemme smoltens utvandring fra elv til hav? I 2007 og 2008 ... -
Spatial and temporal trends of mercury in freshwater fish in Fennoscandia (1965-2015)
Braaten, Hans Fredrik Veiteberg; Åkerblom, Staffan; de Wit, Heleen; Skotte, Gunnar; Rask, Martti; Vuorenmaa, Jussi; Kahilainen, Kimmo K.; Malinen, Tommi; Rognerud, Sigurd; Lydersen, Espen; Amundsen, Per-Arne; Kashulin, Nicholas; Kashulina, Tatiana; Terentyev, Petr; Christensen, Guttorm; Jackson-Blake, Leah Amber; Lund, Espen; Rosseland, Bjørn Olav (NIVA-rapport;7179, Research report, 2017-09)Mercury (Hg) emissions to the atmosphere cause elevated Hg levels in fish, even in many remote regions of the world. Here we present an extensive database of more than 50 000 measurements of Hg in fish, including 2 775 ... -
Transcriptional changes in Atlantic salmon (Salmo salar) after embryonic exposure to road salt
