Biomarkers of oxidative stress in Calanus finmarchicus exposed to a water accommodated fraction of a naphthenic North Atlantic crude oil
(Master thesis, 2018)Calanus finmarchicus is an ecologically important species in the North, Norwegian and Barents Seas, periodically constituting up to 90% of the standing stock of zooplankton. Due to continued development of areas for oil ... -
Chemical Emissions from Indoor Materials in Residential Buildings; A Systematic Mapping Study
(Master thesis, 2017)Exposure to residential emissions have previously been associated with adverse effects on wellness and productivity of the building occupants. This systematic mapping study was conducted with an aim to visually map together ... -
Cytotoxicity and Genotoxicity of Functionalised Multi Walled Carbon Nanotubes in the PLHC-1 Cell Line
(Master thesis, 2015)The field of nanotechnology is rapidly expanding in all sectors of society due to its increasingly large number of applications. This field deals with materials at the nanoscale, defined as having at least one dimension ... -
Detection of trace elements in Svalbard reindeer (Rangifer tarandus platyrhynchus) faeces in Longyearbyen, Adventdalen and Kapp Linné
(Master thesis, 2018)The Arctic is considered a deposition and accumulation region for several possible toxic pollutions, including toxic non-essential elements, that can enter the Arctic environment via long-range transport from other ... -
Dispersion Characterization of Carbon Nanotubes in Freshwater Media and Implications of their Adsorption Behavior for the Bioavailability and acute Toxicity of Phenanthrene in Daphnia magna.
(Master thesis, 2015)To ensure the reproducibility of studies with engineered nanomaterials (ENMs) and to be able to evaluate the study outcomes properly, the state of the investigated ENMs dispersions needs to be characterized. In the course ... -
DNA double strand breaks and chemical elements in incubating female common eiders (Somateria mollissima) in Christiansø, Denmark.
(Master thesis, 2018)Genotoxic agents are ubiquitous in the Baltic Sea and may cause effects not only at a molecular level but at an individual and population level as well. Fasting during reproduction may lead to a state of oxidative stress ... -
DNA Double-Strand Breaks in Arctic Char, Salvelinus alpinus, from Bjørnøya
(Master thesis, 2016)Long-range atmospheric transport has led to persistent organic pollutants (POPs) finding their way far from their sources of origin and into the Arctic and are accumulated in biota. The activity of large seabird colonies ... -
Do levels of per- and polyfluorinated alkylated substances (PFASs) in snow bunting eggs increase with proximity to airports in Svalbard?
(Master thesis, 2017)Per- and polyfluorinated alkylated substances (PFASs) are used in a variety of industrial and consumer applications, including polymer materials and in aqueous fire fighting foam (AFFFs). Research over the last 20 years ... -
Effect of Cadmium on the marine diatoms Seminavis robusta and Phaeodactylum tricornutum: A comparative study
(Master thesis, 2016)Background: Heavy metals cause a harmful effect on marine ecosystems because of their toxicity, persistence and bioaccumulation properties. Cadmium (Cd) is speculated to be a unique heavy metal due to its diverse toxic ... -
Effects of naphthenic North Atlantic crude oil on metabolome profile in Calanus finmarchicus
(Master thesis, 2018)Calanus finmarchicus is an ecologically important species in the North, Norwegian and Barents seas where marine biota is exposed to contaminants discharges due to oil and gas production and transportation. In this experiment, ... -
Effects of produced water on growth and development of Calanus finmarchicus and Calanus hyperboreus early life stages at different temperatures
(Master thesis, 2017)The temperature in the Arctic is increasing, which causes the sea ice to retreat. This opens for more offshore activity and longer shipping season for transportation vessels. The Arctic region is thought to contain large ... -
Effects of Produced Water on the Marine Phytoplankton Phaeodactylum tricornutum - A study of the effects Produced Water, from the Petroleum Industry, can have on Marine Phytoplankton, and the possibilities of a simple yet highly modifiable experimental design
(Master thesis, 2015)Produced Water (PW) is a complex mixture of many chemical compounds, ranging from heavy metals and dispersed oil to Polycyclic Aromatic Hydrocarbons (PAHs), Alkylphenols (APs), and even production chemicals. In the following ... -
Emerging flame retardants and their effects on growth and development in Japanese quails (Coturnix japonica)
(Master thesis, 2016)Tris(1,3-dichloro-2-propyl) phosphate (TDICPP) and Dechlorane Plus (DP) are (re)emerging flame retardants widely detected in the environment and biota. These compounds have shown a potential to bioaccumulate in organisms, ... -
Essential and non-essential elements in feathers of Snow bunting nestlings of Longyearbyen and Adventdalen - Svalbard
(Master thesis, 2016)Abstract One of the important anthropogenic stressors for the natural environment is pollution. The presence of contaminants, such as heavy metals presents great risks for all living organisms, including humans. Therefore, ... -
Exposure of the Common Eider (Somateria mollissima) to toxic elements in relation to migration strategy and wintering area
(Master thesis, 2018)The Common Eider (Somateria mollissima) is a long-lived sea duck with a Holarctic distribution. Eiders within breeding populations have a predictable migration strategy, shown by capture-recapture research using geolocation ... -
Feathers as an integrated measure of organohalogen contamination, dietary tracers and stress in Goshawk (Accipiter gentilis) nestlings from Trøndelag, Norway
(Master thesis, 2015)Because of their high sensitivity and wide distribution, predatory birds have proven useful as sentinel species for monitoring exposure of organohalogen contaminants (OHCs). Nestling feathers have been evaluated as valid ... -
Immunomodulation by metals and environmental pollutants in seabirds breeding on Svalbard
(Master thesis, 2018)This master thesis investigated the levels of arsenic, cadmium, chromium, copper, mercury, lead, selenium and zinc in plasma and feathers of black-legged kittiwakes (Rissa tridcatyla) (n = 17), as well as feathers of ... -
