Method Development for Rapid Determination of Organophosphorus Flame Retardant Exposure in Harbor Porpoises Along the Norwegian Coast
(Master thesis, 2020)Ved å bruke UHPLC-QqQ-MS/MS og væske-væske ekstraksjon som raske og effektive metoder for å bestemme kjemisk tilstedeværelse, sikter denne studien på å utvikle feltet rundt marin spredning av organofosforerte flammehemmere, ... -
Per- and polyfluoroalkyl substances in shorebirds of Australia
(Master thesis, 2020)Australske kystomåder og våtmarker innehar viktige habitater for dyreliv. I disse områdene forbereder trekkfugler seg på sin kommende reise til hekkeområder i nord ved å søke etter mat for å samle opp energi. Kystfugler ... -
Endocrine Disrupting Substances in Infant Foodstuffs - Presence of Perfluoroalkyl Substances and Toxic Elements
(Master thesis, 2020)Per- og polyfluorinerte stoffer (PFAS) har den siste tiden fått mye oppmerksomhet på grunn av deres hormonforstyrrende egenskaper. PFAS er påvist i naturprøver i mange deler av verden og det er derfor grunn til bekymring ... -
Parabens and triclocarban in baby foodstuffs
(Master thesis, 2020)For forbrukersikkerhet og kvalitetssikring av forbrukerartikler, er tilsetning av bakteriebekjempende kjemikalier strengt regulert, både med hensyn på merking og mengde. Alkylestere av parahydroksibenzosyre, kalt parabener, ... -
Total synthesis of Dothideopyrone E and Dothideopyone F
(Master thesis, 2021)Dette arbeidet er relatert til syntesen av to naturprodukter, dothideopyrone E og F. Ulike veier har blitt prøvd for å syntetisere disse molekylene. I de første testene ble en Carreira-alkynylering utført for å oppnå gode ... -
Occurrence of Bisphenols and Benzophenone UV Filters in White-Tailed Eagles (Haliaeetus albicilla) from Smøla, Norway
(Journal article; Peer reviewed, 2021)There is a growing concern about the occurrence of bisphenols and benzophenone UV filters in natural ecosystems, while data are limited regarding their actual occurrence in wildlife species, especially in raptors. In this ... -
Accelerated hydrolysis method for producing partially degraded polyester microplastic fiber reference materials
(Peer reviewed; Journal article, 2020)Microplastic fibers (MPFs) from textiles significantly contribute to the microplastic (MP) load in many environmental matrices and have been shown to negatively impact the organisms therein. Most fate and effect studies ... -
A simple hanging mercury drop electrode
(Peer reviewed; Journal article, 2000)A device producing reproducible hanging mercury drops at the end of a glass capillary is described. Mercury flow through th capillary is controlled by means of a closing needle actuated by an electromagnetic relay. The ... -
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 ... -
Catalytic cathodic stripping voltammetry of oxidized glutathione at a hanging mercury drop electrode in the presence of nickel ion
(Peer reviewed; Journal article, 1995)Oxidized glutathione (GSSG) can be determined after previous accumulation on the HMDE at E > −0.2 V (vs. the reference electrode). GSH is formed during the accumulation, possibly by a mercury-ion-assisted hydrolytic ... -
Moving forward in microplastic research: A Norwegian perspective
(Peer reviewed; Journal article, 2021)Given the increasing attention on the occurrence of microplastics in the environment, and the potential envi-ronmental threats they pose, there is a need for researchers to move quickly from basic understanding to applied ... -
The Development of Polydimethysiloxane/ZnO–GO Antifouling Coatings
(Peer reviewed; Journal article, 2021)The development of antifouling coating for sensor is desirable because the biofilm can shorten sensor’s life and cause inaccurate reading. In this study, a facile one-pot reaction was used to synthesized ZnO–graphene oxide ... -
Chemical Analysis and Anthelmintic Activity Against Teladorsagia Circumcincta of Nordic Bark Extracts In vitro
(Peer reviewed; Journal article, 2021)Helminth parasitic infections are common in small ruminants in Norway; infection is usually treated with anthelmintic drugs, but anthelmintic resistance is an increasing problem. It is necessary to identify strategies to ... -
Rapid determination of thyroid hormones in blood plasma from Glaucous gulls and Baikal seals by HybridSPE®-LC-MS/MS
(Peer reviewed; Journal article, 2021)A rapid hybrid solid phase extraction (HybridSPE®) protocol tailored to liquid chromatography–electrospray ionization tandem mass spectrometry (LC–ESI–MS/MS) analysis, was developed for the determination of four thyroid ... -
Massively Parallel Arrays of Size-Controlled Metallic Nanogaps with Gap-Widths Down to the Sub-3-nm Level
(Peer reviewed; Journal article, 2021)Metallic nanogaps (MNGs) are fundamental components of nanoscale photonic and electronic devices. However, the lack of reproducible, high-yield fabrication methods with nanometric control over the gap-size has hindered ...
