Antioxidant enzyme system in fish from contaminated lakes in Chernobyl exclusion zone
Løkken, Vilde Karlsen (Master thesis, 2020)Akvatiske organismer i Tsjernobyl-eksklusjonssonen har blitt kronisk eksponert for ioniserende stråling siden atomkraftulykken i Tsjernobyl i 1986. Fisk anses som de mest radiosensitive akvatiske organismene, og i den høyt ... -
The effect of tunnel construction particles on Daphnia magna
Oma, Thea (Master thesis, 2022)Particles originating from drilling and blasting during tunnel construction have the potential to end up in the environment, however, there is a knowledge gap concerning the effect of these particles on aquatic biota. In ... -
Long term biological effects of ionizing radiation on the eye development in gamma-irradiated Atlantic salmon embryos
Mork, Oscar (Master thesis, 2021)Organisms are at their most sensitive to ionizing radiation during the embryonic life stage, and the eye is one of the most sensitive tissues. High proliferation-rate, cell-differentiation and embryonic development depend ... -
Metal mixtures, assessing speciation models to predict uptake in Brown Trout (Salmo trutta)
Napast, Denis (Master thesis, 2018)Alum shale is an organic-rich rock which contains high concentrations of U, Ni, V, Mo, Co, Cu, Zn, As and other metals. These metals are released into the environment by human actives and rock weathering. Many different ... -
Spredning og kildekarakterisering av polysykliske aromatiske hydrokarboner (PAH) fra rensebasseng for veiavrenning og tunnelvask
Myhre, Helena Seland (Master thesis, 2021)Veitrafikken medfører utslipp av en rekke forurensningsstoffer, deriblant polysykliske aromatiske hydrokarboner (PAH) som er en gruppe persistente, organiske miljøgifter med stor spredning i naturen. Stoffene avsettes på ... -
Stable isotope ratio to identify potential food chain transfer of 137Cs in fish with special focus on rudd (Scardinius Erythrophthalmus)
Øvergaard, Jørund Mikael (Master thesis, 2022)The uptake of radionuclides such as radiocaesium (137Cs) in fish occurs mainly through diet. Generally, it is assumed that the transfer of 137Cs in predatory fish is higher than in non-predatory fish. In the present work ... -
The transfer of radiocesium in coastal waters : radiocesium tracer to investigate mixing zone processes in brackish waters
Kvamme, Birgitte Brockstedt (Master thesis, 2019)In the event of a reactor accident, debris plumes containing artificially produced radionuclides could impose a great risk for the environment in distances far from the accident site. Radionuclides can enter the marine ... -
Trace metal speciation and uptake in Atlantic salmon (Salmo salar) in coastal water
Nymo, Malene Therese (Master thesis, 2020)Estuarine environments have a high risk of metal pollution due to the influx from rivers. Freshwater from rivers mixed with seawater in coastal areas gives varied and complex water chemistry. In the estuarine environment ... -
Transfer of river-discharged Cs-137 in estuaries : a case study from Vefsna river and the Vefsnfjord in Nordland, Norway
Larsen, Marie (Master thesis, 2021)Several decades after the Chernobyl accident, it is still detectable activities of Cs-137 in the environment. Norway was highly affected by radioactive fallout, where one of the locations that received the highest doses ... -
Transfer of strontium in the potato plant, solanum tuberosum L., following single foliar wet deposition : field experiments performed in Eastern Norway and at the West Coast of Norway
Østmoe, Stine (Master thesis, 2020)90Sr is one of the most important and frequent radioactive products from nuclear fission. If ingested, it is considered a major hazard to humans due to high retention in skeleton, leading to irradiation of cells and cancer ... -
Utlekking av metaller fra sprengsteinslam fra ikke-syredannende bergarter
Hansen, Aurora (Master thesis, 2022)Anleggsvann fra tunnelprosjekt kan ha avrenning med høye konsentrasjoner av partikler. Det har de siste årene vært økende fokus på utlekking av metaller fra syredannende bergarter til anleggsvann. Det er kjent at det er ...
