(Master thesis / Masteroppgave, 2005)SAMMENDRAG Heksabromosyklododekan (HBCD) er en bromert flammehemmer, hovedsakelig tilsatt produkter av polystyren og tekstiler. Stoffet kan spres i miljøet under produksjon av produkter som inneholder flammehemmere, samt ...
-
(Master thesis / Masteroppgave, 2005)Cholinesterase (ChE) activity is a recognised biomarker of organophosphorus (OP) insecticide exposure. It is frequently applied to earthworms in the field of agriculturally linked ecotoxicology, because of the use of OP ...

Exploring co-genotoxicity of chemicals using traditional experimental methods and microarray systems (Master thesis / Masteroppgave, 2005)Due to the use of a great number of existing chemicals and many new being produced, there is a strong need for efficient and cost-effective methods, in order to classify and regulate the use and release of these potential ...
-
(Master thesis / Masteroppgave, 2005)Sediment har gjennom antropogen kontaminering blitt sterkt påvirket og i flere havneområder er det sterkt forurenset. Forurenset havbunn vil påvirke livet som lever i og over den. Finnes det gode alternativer til å teste ...

(Master thesis / Masteroppgave, 2005)Norwegian: Ulike epidemiologiske studier har assosiert luftforurensning og dieseleksos med økt risiko for lungekreft. Dieseleksos inneholder en rekke ulike polysykliske aromatiske hydrokarboner (PAH) og nitrosubstituerte-PAH ...
-
(Master thesis / Masteroppgave, 2005)Abstract The common compost earthworm Eisenia fetida was used for toxicity testing of mercury, in a well-characterized agricultural soil obtained from a local field (Ås, Norway). Groups of five or ten clitellate earthworms ...
-
(Master thesis / Masteroppgave, 2006)Environmental estrogens may modulate the endocrine system through interactions with sex steroid-binding protein (SBP), and these processes may be a novel mechanism for endocrine disruption. The endogenous hormone 17â-estradiol ...
-
(Master thesis / Masteroppgave, 2006)Fluorinated compounds (PFAS) and tributyltin (TBT) are found in significant amounts in the seas around the world and it is therefore of interest to know whether, and how, they affect coastal ecosystems. Three sediment-dwelling ...
-
(Master thesis / Hovedoppgave, 2006)Bromerte flammehemmere (BFR) er persistente og hydrofobe kjemikalier som har vist seg å kunne akkumuleres i forskjellige organismer, inkludert mennesker og miljø. Det globale omfanget av disse forurensningene gir grunn til ...
-
(Master thesis / Masteroppgave, 2006)Methyl mercury (MeHg), polychlorinated biphenyls (PCB) and some brominated flame retardants (BFR) are all neurotoxic compounds, known to exert their effects through their influence on neurotransmitter transport. Even though ...
-
(Master thesis / Masteroppgave, 2006)Abstract Perfluorinated alkylated substances (PFAS) are persistent compounds with many uses, for example impregnation of fabrics and leather and as fire-retardants. Recently, it has focused on these compounds, because of ...
-
(Master thesis / Hovedoppgave, 2006)Cisplatin-based chemotherapy is known to be exceptionally effective in the treatment of testicular germ cell tumors. The molecular mechanisms underlying the sensitivity of testicular germ cell tumor cell lines to cisplatin ...
-
(Master thesis / Masteroppgave, 2006)Sammendrag Dyr og mennesker blir eksponert for svært mange stoffer, både gjennom miljøet og føden. Grenseverdier for akseptabel eksponering for disse stoffene blir med få unntak bestemt fra enkeltstoffenes effekter alene, ...
-
(Master thesis / Masteroppgave, 2006)In the studies described in this manuscript, a new cellular model system has been developed and two fluorometric assays have been assessed for their applicability in biomonitoring and in vitro toxicity testing. Echinoderm ...
-
(Master thesis / Masteroppgave, 2006)Within biomonitoring it has been common practice to analyse the concentration of pollutants in organisms. However, focus is shifting towards an approach which combines chemical analyses with measurements of effects in ...
-
(Master thesis / Masteroppgave, 2007)The release of persistent organic pollutants (POPs) into the environment for many decades has led to a worldwide contamination. The impact of pollutants on ecosystem and human health is an urgent and international issue ...
-
(Master thesis / Masteroppgave, 2007)Iodinated x-ray contrast media (ICM) are used to improve the visibility of internal structures of the body in an x-ray image due to their ability to attenuate x-rays, providing enhanced contrast between regions of interest ...
