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;6245-2011, 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 ... -

Mahrosh, Urma (PhD Thesis;2015:66, Doctoral thesis, 2017-07-12)Application of road deicing salt in the Nordic countries have increased considerably over the years, in order to enhance good friction and thereby increasing the traffic safety on icy roads during the winter period. The ... -
Sammenhengen mellom labilt aluminium og pH i kalkede laksevassdrag
Hindar, Atle; Garmo, Øyvind Aaberg; Teien, Hans-Christian (Research report, 2015)I kalkede laksevassdrag er det satt miljømål i form av differensierte pH-grenser (pH 6,0-6,4), og i vannforskriften er det satt en grense mellom god og moderat tilstand på 10 µg/L for labilt aluminium, LAl (positivt ladd ... -

Silver nanomaterials in aquatic systems : linking uptake and effects in biota to exposure characterization
Kleiven, Merethe (PhD Thesis;2019:10, Doctoral thesis, 2019)The potential environmental impacts of engineered nanomaterials (ENMs) have received increased attention over the last decades. While the benefits of the development and use of ENMs are numerous (e.g., improved medical ... -
Spredning og kildekarakterisering av polysykliske aromatiske hydrokarboner (PAH) fra rensebasseng for veiavrenning og tunnelvask

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 effect of freezing and thawing on transport of pesticides through macroporous soils and the potential risk towards the aquatic environment
