Journal ArticleDOI
UV degradation of natural and synthetic microfibers causes fragmentation and release of polymer degradation products and chemical additives
Lisbet Sørensen,Anette Synnøve Groven,Ingrid Alver Hovsbakken,Oihane Del Puerto,Daniel Franklin Krause,Antonio Sarno,Andy M. Booth +6 more
TL;DR: A range of molecular degradation products were identified in seawater leachates after UV exposure, with increasing abundance over the duration of the experiment, and a variety of additive chemicals were shown to leach from the MFs into seawater.
Journal ArticleDOI
Embryonic exposure to produced water can cause cardiac toxicity and deformations in Atlantic cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) larvae.
Bjørn Henrik Hansen,Lisbet Sørensen,Trond Røvik Størseth,Raymond Nepstad,Dag Altin,Daniel Franklin Krause,Sonnich Meier,Trond Nordtug +7 more
TL;DR: Exposure of embryos of Atlantic cod and haddock to produced water extracts equivalent to 1:50, 1:500 and 1:5000 times dilutions of raw effluent resulted in significant reduction in survival or hatching success, however, for cod, hatching was initiated earlier for exposed embryos in a concentration-dependent manner.
Journal ArticleDOI
Exposure to crude oil micro-droplets causes reduced food uptake in copepods associated with alteration in their metabolic profiles.
Bjørn Henrik Hansen,Bjørn Henrik Hansen,Dag Altin,Trond Nordtug,Ida Beathe Øverjordet,Anders J. Olsen,Daniel Franklin Krause,Ingvild Fladvad Størdal,Trond Røvik Størseth +8 more
TL;DR: This work clearly displays a relationship between crude oil micro-droplet exposure and reduced uptake of algae in copepods and contributes to some of the observed effects triggering a starvation-type response.
Journal ArticleDOI
Interfacial tension between oil and seawater as a function of dispersant dosage
TL;DR: A general expression for IFT(oil-water) as a function of dispersant dosage is proposed based on the compiled data, which is needed by algorithms to predict oil droplet sizes from subsea releases.
Journal ArticleDOI
Biotransformation of natural gas and oil compounds associated with marine oil discharges.
TL;DR: Experiments with local seawater from a Norwegian fjord to examine if the presence of dissolved gas compounds affected biodegradation of volatile oil compounds, and if oil compounds likewise affected gas compound oxidation showed comparable oil compound biotransformation rates in seawater at 5 °C.
