Lead concentrations in blood from incubating common eiders (Somateria mollissima) in the Baltic Sea.
Lam, Su Shiung; Mcpartland, Molly; Noori, Brenley; Garbus, Svend-Erik; Lierhagen, Syverin; Lyngs, Peter; Dietz, Rune; Therkildsen, Ole Roland; Christensen, Thomas Kjær; Tjørnløv, Rune Skjold; Kanstrup, Niels; Fox, Anthony D.; Sørensen, Iben Hove; Arzel, Céline; Krøkje, Åse; Sonne, Christian (Journal article; Peer reviewed, 2020)Here we investigate if lead may be a contributing factor to the observed population decline in a Baltic colony of incubating eiders (Somateria mollissima). Body mass and blood samples were obtained from 50 incubating female ... -
Lead isotopic signatures in blood from incubating common eiders (Somateria mollissima) in the central Baltic Sea
Mcpartland, Molly; Garbus, Svend-Erik; Lierhagen, Syverin; Sonne, Christian; Krøkje, Åse (Peer reviewed; Journal article, 2020)The Christiansø colony of common eiders (Somateria mollissima) in the central Baltic Sea were exposed to high levels of Pb during the 2018 breeding season that were not present in 2017. Due to these high Pb blood levels, ... -
Level and potential genotoxic effects of perfluoralkyl substances in three arctic seabird species
Larsen, Christina Moen (Master thesis, 2022) -
Levels and Potential Genotoxic Effects of Organohalogenated Contaminants in Seabird Eggs from Svalbard
Rodvelt, Randi Haarstad (Master thesis, 2018)Organohalogenated contaminants (OHCs) have been detected in relative high levels in arctic seabirds and eggs and are of great concern due to their potential toxic effects. OHCs are incorporated into the eggs during egg ... -
Levels, patterns, and biomagnification potential of perfluoroalkyl substances in a terrestrial food chain in a Nordic Skiing Area
Grønnestad, Randi; Vazquez, Berta Perez; Arukwe, Augustine; Jaspers, Veerle; Jenssen, Bjørn Munro; Karimi, Mahin; Lyche, Jan Ludvig; Krøkje, Åse (Journal article; Peer reviewed, 2019)Perfluoroalkyl substances (PFASs) are used in a wide range of consumer products, including ski products, such as ski waxes. However, there is limited knowledge on the release of PFASs from such products into the environment ... -
Metal Levels in Blood and Feather from Incubating Female Common Eiders (Somateria mollissima) in Svalbard.
Lervik, Kjersti (Master thesis, 2012)In the present study, the concentration of selected metals and metalloids were determined in blood and feathers of 29 incubating female common eiders (Somateria mollissima). The birds were sampled at the island Storholmen ... -
Mutagenic Potential of Spruce-derived fast Pyrolysis Oil measured by the Ames Salmonella assay
Holteberg, Nina (Master thesis, 2014)Biomass conversion to biofuels is promising for production of renewable energy. Biofuels are sustainable, CO2-neutral, recognized to be cleaner than fossil fuels, but their combustion generates noxious gases and genotoxic ... -
Mutagenicity and induction of CYP1A- enzymes from organic extracts of soil samples from nursery schools, evaluated by in vitro studies
Thorsen, Marte Høye (Master thesis, 2011)Polluted soil can be a problem in urban areas, and can have a direct impact on human health upon exposure. The toxic potential of mixtures can be mediated by constituents and information about toxicity of mixtures is ... -
Occurrence of perfluorinated alkylated substances (PFASs) and evaluation of potential genotoxic effects in small rodents from a skiing area, Granåsen, Norway
Pérez Vázquez, Berta (Master thesis, 2018)The aim of the project is to sample small mammals from Granåsen, a PFAS hotspot area, and compare them to the population of Jonsvatnet, chosen as a reference area. -
Per- and polyfluoroalkyl substances (PFAS) in ski products: Environmental contamination, bioaccumulation and effects in rodents
Grønnestad, Randi (Doctoral theses at NTNU;2021:328, Doctoral thesis, 2021)Per- and polyfluoroalkyl substances (PFAS) are a group of anthropogenic contaminants that are widespread in the environment. Due to the strong persistency and water and lipid repellency, PFAS have been used in a wide range ... -
Pollutant Levels, Antioxidants and Potential Genotoxic Effects in Incubating Female Common Eiders (Somateria mollissima)
Fenstad, Anette A. (Doctoral thesis at NTNU;2016:189, Doctoral thesis, 2016)In the present thesis, environmental exposure to 18 persistent organic pollutants (POPs) and 8 elements, as well as potential antioxidant responses and genotoxic effects in incubating female common eiders (Somateria ... -
Strømme syndrom - Jakten på et gen
Brandal, Kristin (Master thesis, 2011)I 2005 ble en ny type sekvenseringsteknologi introdusert som åpnet for uante muligheter innen genetikken. Prosjekter som tidligere ble ansett som uoverkommelige, både teknisk og økonomisk, kan nå gjennomføres. Sekvenseri ... -
Toxic and Genotoxic Effects of Fast Pyrolysis Oils Generated from Three Different Feedstocks Evaluated in an Allium cepa Chromosome Aberration Assay
Holan, Ida Øverås (Master thesis, 2014)Non-renewable energy sources cover the majority of today s energy demand. However, due to uncertainty of available petroleum reserves and great environmental impacts associated with the use of petroleum, renewable energy ... -
