Determination of Poly Chlorinated biphenyls in sediment of Trondheim fjord (Norway) and Lake Tana (Ethiopia) using pressurized liquid extraction (PLE) and Gas Chromatography - Mass Spectrometry (GC-MS)
(Master thesis, 2017)The presence of polychlorinated biphenyls (PCBs) in the environment is of great concern, as they are compounds that are hazardous to the environment and human health. Environmental investigations of PCBs can be challenging ... -
The Determination of Polycyclic Aromatic Hydrocarbons (PAHs) with HPLC-DAD-FLD and GC-MS Techniques in the Dissolved and Particulate Phase of Road-Tunnel Wash Water: A Case Study for Cross-Array Comparisons and Applications
(Peer reviewed; Journal article, 2022)Accelerated solvent extraction (ASE) and solid phase extraction (SPE) protocols tailored to either gas chromatography mass spectrometry (GC-MS) or high-performance liquid chromatography coupled to diode-array and fluorescence ... -
Determination of profiles of occurrence of parabens, triclocarban and elements in select snack foodstuffs from Norway and other countries
(Master thesis, 2019)Processed food stuffs are added chemicals to keep stable quality for long periods. While the additives give positive effect to ordinary life, some of these also possibly cause estrogenic problem for our health. Therefore, ... -
Determination of profiles of trace elements and emerging contaminants (PFCs) in feathers and blood samples from birds - a multi-species approach
(Master thesis, 2019)Fjær- og blodprøver fra en rekke fuglearter ble samlet i Norge og Hellas (2015-2018) for å vurdere forekomst og se på profiler til utvalgte spormetaller og organiske forurensninger. De utvalgte essensielle sporstoffene ... -
Determination of steroid hormones in grey seal (Halichoerus grypus) blood plasma using convergence chromatography tandem mass spectrometry
(Peer reviewed; Journal article, 2023)A hybrid solid phase extraction (HybridSPE) protocol tailored to ultra-performance convergence chromatography tandem mass spectrometry (UPC2-MS/MS) was developed for the determination of 19 steroid hormones in grey seal ... -
Determination of the Oxidative Stress Biomarkers of 8-Hydroxydeoxyguanosine and Dityrosine in the Gills, Skin, Dorsal Fin, and Liver Tissue of Atlantic Salmon (Salmo salar) Parr
(Peer reviewed; Journal article, 2022)Oxidative stress is a condition caused by an imbalance in the occurrence of reactive oxygen species in the cells and tissues of organisms. An ultra-performance liquid chromatography–electrospray ionization tandem mass ... -
Developing synthesis route for CuSAPO-18
(Master thesis, 2019)I dette arbeidet ble synthese av SAPO-18 med kobber isomorfisk substituert forsøkt via en hydrotermisk metode. Metoder basert på di-isopropyletylamin (DIPEA) ble funnet til å redusere deler av eller alt kobberet til ... -
