(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, 2011)Abstract Living organisms are usually exposed to combinations of a number of physical and chemical environmental factors in their natural habitats. Pre-exposure to sub lethal doses of a chemical may induce enhanced tolerance ...
-
(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, 2009)Exposure to environmental toxicants is a contributing factor to health disorders such as cancer, asthma and allergy. A toxicant which has been studied more in depth the last years is the well known neurotoxicant acrylamide ...
-
(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 ...
-
(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, 2011)Torsk er en viktig organisme i Norge økonomisk, økologisk og som en matkilde. Atlanterhavstorsk i indre Oslofjord er eksponert for en rekke miljøgifter. Det er derfor viktig å overvåke helsen til torsken. I denne oppgaven ...

(Master thesis / Masteroppgave, 2011)Drug overdose is a major cause of premature death among heroin users and there has been a call for studies to identify risk factors for fatal overdoses to improve preventive interventions. The majority of heroin related ...
-
(Master thesis / Masteroppgave, 2008)Abstract This study investigates four halogenated substances; three polyfluorinated compounds and one brominated substance. The polyfluorinated compounds, namely 6:2 fluorotelomer alcohol (6:2 FTOH), 8:2 fluorotelomer ...
-
(Master thesis / Masteroppgave, 2008)Discharge from offshore activities to the sea may seriously affect the surrounding environment and cause disturbances in communities and ecosystems close to oil production installations. A major part of the waste released ...
-
(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, 2011)We show that nitrated-polycyclic aromatic hydrocarbons (nitro-PAHs) induce cell death in Hepa1c1c7 cells, as measured by fluorescence microscopy. BEAS-2B cells, however did not show any relevant effects. 1.3-DNP induce ...
-
(Master thesis / Masteroppgave, 2010)The main aim of this study was to investigate effects of the perfluorinated compounds perfluorooctanesulphonate (PFOS) and perflouorononanoic acid (PFNA) using the human adrenocortical carcinoma cell line – H295R. ...
