Application of chemical herders do not increase acute crude oil toxicity to cold-water marine species
Hansen, Bjørn Henrik; Nordtug, Trond; Øverjordet, Ida Beathe; Altin, Dag; Farkas, Julia; Daling, Per Snorre; Sørheim, Kristin Rist; Faksness, Liv Guri (Peer reviewed; Journal article, 2022)Chemical herders may be used to sequester and thicken surface oil slicks to increase the time window for performing in situ burning of spilled oil on the sea surface. For herder use to be an environmentally safe oil spill ... -
Biodegradation of oil spill dispersant surfactants in cold seawater
Brakstad, Odd Gunnar; Størseth, Trond Røvik; Brunsvik, Anders; Bonaunet, Kristin; Faksness, Liv Guri (Journal article; Peer reviewed, 2018)While biodegradation of chemically dispersed oil has been well documented, only a few studies have focused on the degradation of the dispersant compounds themselves. The objective of this study was to determine the ... -

Faksness, Liv Guri; Altin, Dag; Størseth, Trond Røvik; Nordtug, Trond; Hansen, Bjørn Henrik (Journal article; Peer reviewed, 2020-05)Macondo source oils and artificially weathered oil residues from 150 °C+ to 300 °C+, including artificially photo oxidized oils, were prepared and used for generating low energy water accommodated fractions (LE-WAFs) in ... -
Establishing a link between composition and toxicity of offshore produced waters using comprehensive analysis techniques – A way forward for discharge monitoring?
Sørensen, Lisbet; McCormack, Paul; Altin, Dag; Robson, William J.; Booth, Andy; Faksness, Liv Guri; Rowland, Steven J; Størseth, Trond Røvik (Journal article; Peer reviewed, 2019)Extracts of produced waters from five mature Norwegian Sea oil fields were examined as total organic extracts (TOEs) and after fractionation into operationally-defined ‘polar’ and ‘apolar’ fractions. The TOEs and fractions ... -
