Toxic and Genotoxic Effects of Fast Pyrolysis Oils Generated from Three Different Feedstocks Evaluated in an Allium cepa Chromosome Aberration Assay
(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 ... -
Toxic effects of a petroleum-based and a biodegradable MP on Daphnia magna
(Master thesis, 2022)Plast er vedvarende og allestedsnærværende på land og i akvatiske habitater. Mikroplast (MP; plastpartikler < 5 mm) fragmenteres vanligvis fra større plastbiter på grunn av for eksempel UV-stråling. Tidligere studier viser ... -
Toxicity and developmental effects of Arctic fuel oil types on early life stages of Atlantic cod (Gadus morhua)
(Journal article; Peer reviewed, 2021)Due to the heavy fuel oil (HFO) ban in Arctic maritime transport and new legislations restricting the sulphur content of fuel oils, new fuel oil types are continuously developed. However, the potential impacts of these new ... -
Toxicity and Genotoxicity of five pyrolytic Bio-Oils produced from Wood, measured as Root Growth Inhibition and DNA Double-Strand Breaks in Allium cepa
(Master thesis, 2014)Pyrolytic bio-oil is considered as a potential renewable energy resource that might replace fossil fuels in the future. Chemically, bio-oils are highly complex mixtures consisting of several hundred different compounds, ... -
Toxicity of microplastics and natural particles in the freshwater dipteran Chironomus riparius: Same same but different?
(Journal article; Peer reviewed, 2019)Microplastics (MP) are contaminants of emerging concern in aquatic ecosystems. While the number of studies is rapidly increasing, a comparison of the toxicity of MP and natural particulate matter is largely missing. In ... -
Toxicogenomics of Aryl Hydrocarbon- and Estrogen Receptor Interactions in Fish: Mechanisms and Profiling of Gene Expression Patterns in Chemical Mixture Exposure Scenarios
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:264, Doctoral thesis, 2007)Almost without exception, biological processes such as overt morphological changes, development (both reproductive and growth), toxicological responses and clinical manifestation to disease, have molecular basis. From our ... -
Trace element concentrations in feathers and blood of Northern goshawk (Accipiter gentilis) nestlings from Norway and Spain
(Journal article; Peer reviewed, 2017)Information on trace element pollution in the terrestrial environment and its biota is limited compared to the marine environment. In the present study, we collected body feathers and blood of 37 Northern goshawk (Accipiter ... -
Trace elements in whole blood in the general population in Trøndelag County, Norway: The HUNT3 Survey
(Journal article; Peer reviewed, 2021)Background: Biomonitoring of a cohort within a large health survey can provide reliable information on trace element status. The main aims of this study were 1) to determine the concentrations of 28 trace elements in whole ... -
Trace metal mobility in sub-seabed sediments by CO2 seepage under high-pressure conditions
(Peer reviewed; Journal article, 2020)Carbon capture and storage (CCS) is the third contributor to cumulative carbon emission reductions required by the second half of this century. Although this is a promising technology for reducing atmospheric CO2, it is ... -
Tracing the fate of escaped farmed cod (Gadus morhua L.) in a Norwegian fjord system
(Doctoral thesis at NTNU;2016:116, Doctoral thesis, 2016)Summary of thesis: The aim of this thesis was to investigate the fate of escaped farmed cod and detect any introgression in the local stock. Phenotypic discrimination of wild and farmed cod, and genetic baseline values ... -
Tracing the footprints of Arctic pollution: Spatial variations in toxic and essential elements in Svalbard reindeer (Rangifer tarandus platyrhynchus) faeces
(Journal article; Peer reviewed, 2023)The Arctic is an accumulation zone of long-range transported pollution. In addition, local anthropogenic activities further contribute to regional pollution levels. The Svalbard reindeer (Rangifer tarandus platyrhynchus) ... -
Tracking jellyfish swarm origins using a combined oceanographic-genetic-citizen science approach
(Peer reviewed; Journal article, 2022)Biological invasions of jellyfish may critically affect ecosystems and ecosystem services, yet their complex life cycle makes tracking their origins and dispersal vectors a challenging task. Here we combine citizen science ... -
Tracking pan-continental trends in environmental contamination using sentinel raptors—what types of samples should we use?
(Journal article; Peer reviewed, 2016)Biomonitoring using birds of prey as sentinel species has been mooted as a way to evaluate the success of European Union directives that are designed to protect people and the environment across Europe from industrial ... -
Trait evolvability: effects of thermal plasticity and genetic correlations among traits
(Doctoral theses at NTNU;2018:377, Doctoral thesis, 2018)Summary of thesis: Trait evolvability: effects of thermal plasticity and genetic correlations among traits Climate change and increasing average temperatures are a big challenge for many populations of plants and ... -
Trans-Equatorial Migration Routes, Staging Sites and Wintering Areas of a High-Arctic Avian Predator: The Long-tailed Skua (Stercorarius longicaudus)
(Journal article; Peer reviewed, 2013)The Long-tailed Skua, a small (,300 g) Arctic-breeding predator and seabird, is a functionally very important component of the Arctic vertebrate communities in summer, but little is known about its migration and winter ... -
Transcriptional development of phospholipid and lipoprotein metabolism in different intestinal regions of Atlantic salmon (Salmo salar) fry
(Journal article; Peer reviewed, 2018)Background It has been suggested that the high phospholipid (PL) requirement in Atlantic salmon (Salmo salar) fry is due to insufficient intestinal de-novo synthesis causing low lipoprotein (LP) production and reduced ... -
Transcriptional profiling of reproductive development, lipid storage and molting throughout the last juvenile stage of the marine copepod Calanus finmarchicus
