(Master thesis / Masteroppgave, 2013)Precise estimation of toxicity is essential in the risk assessment of hydrophobic organic compounds (HOCs). Toxicity testing of HOCs in aquatic bioassays is particularly challenging due to loss of substance from the water ...
-
(Master thesis / Masteroppgave, 2013)The present study is part of an ongoing effort to monitor the pollution situation in the inner Oslofjord. The purpose of the study was to investigate effects of pollutants on the resident cod population in the area. The ...
-
(Master thesis / Masteroppgave, 2013)Perfluorooctanoic acid (PFOA) and fluoranthene are organic pollutants with a widespread environmental occurrence. They are both present in the environment, and are known to concentrate and bioaccumulate in organisms, PFOA ...
-
(Master thesis / Masteroppgave, 2013)Claviceps purpurea is a phytopathogenic ascomycete that parasitizes various grasses, most notably rye. Instead of a grain the infected host plant produces a fungal sclerotium in the autumn, containing toxic indole-alkaloids ...
-
(Master thesis / Masteroppgave, 2013)Marine organisms are exposed to a wide range of potentially hazardous substances, from natural and/or anthropogenic sources. Organisms in polluted sediments may accumulate high amounts of chemical contaminants and transfer ...

Toxicity of various mycotoxins to immune cells in vitro, with focus on morphological and phenotypic changesRestricted Access (Master thesis / Masteroppgave, 2013)Mycotoxins is a unwanted contaminant on grain, corn and fruits and are reported to be found in increasing amounts also in processed food. There is an increasing focus on mycotoxins worldwide regarding their deleterious ...
-
(Master thesis / Masteroppgave, 2014)There are multiple environmental factors that can affect the toxicity of a chemical to an organism in its natural environment. These include temperature, humidity, predation, competition, diseases, and presence of other ...
-
(Master thesis / Masteroppgave, 2014)Juvenile Atlantic cod (Gadus morhua) were exposed to water-accommodated fractions (WAFs) of Arabian light crude oil in two concentrations for one, two or three weeks. The last group was exposed for three weeks followed by ...
-
(Master thesis / Masteroppgave, 2014)Utslipp av miljøgifter til miljøet skyldes ofte ulike typer urbane og industrielle aktiviteter. En stor andel av miljøgiftene vil ende opp i akvatiske økosystemer som følge av direkte utslipp eller indirekte utslipp via ...
-
(Master thesis / Masteroppgave, 2014)The purpose of this study was to characterise biotransformation and immune responses in juvenile Atlantic cod (Gadus morhua) following exposure for 2, 8 and 16 days to the water-soluble fraction of North Sea crude oil in ...
-
(Master thesis / Masteroppgave, 2014)Piggvar (Scophthalmus maximus) ble eksponert for den vannløselige fraksjonen av Ekofisk råolje i et gjennomstrømmingssystem i 16 dager. Delvis nedbrutt olje ble fordelt på grus i kolonner med konsentrasjoner på 6, 12 og ...

(Master thesis / Masteroppgave, 2014)Heroin is the main abused opioid, and is causing most drug use related deaths in the European Union and in the USA. New treatment strategies for heroin addiction are needed, and an alternative could be modulation of the ...
-
(Master thesis / Masteroppgave, 2014)Nanotechnology is a growing industry bringing with the increasing utilization of nanoparticles (NP). NPs are defined as particles with at least one dimension being smaller than 100 nm. They are an increasing concern because ...
-
(Master thesis / Masteroppgave, 2014)Abstract It is not known whether exposure to persistent organic pollutants (POPs) cause epigenetic changes in marine mammals. Ringed seals are a key species at the higher trophic levels of arctic marine ecosystems, and may ...
