Biodegradation in seawater of PAH and alkylphenols from produced water of a North Sea Platform
(Journal article; Peer reviewed, 2018-09)Operational planned discharges of produced water (PW) to the marine environment from offshore oil production installations, contain low concentrations of dispersed oil compounds, like polycyclic aromatic hydrocarbons (PAH) ... -
Biodegradation of Dispersed Oil in natural Seawaters from Western Greenland and a Norwegian fjord
(Journal article; Peer reviewed, 2018-07-25)With increasing oil exploration, production and transportation in the Arctic, predictions of the fate of spilled oil become important, including oil compound biodegradation. The use of chemical dispersants may result in ... -
Biodegradation-mediated alterations in acute toxicity of water-accommodated fraction and single crude oil components in cold seawater
(Journal article; Peer reviewed, 2018-08)Hydrocarbon biodegradation may be slower in cold Arctic than in temperate seawater, and this will affect the toxicity time window of the hydrocarbons. In this study, the acute toxicities of water-soluble phases of ... -
Biotransformation in water and soil of nitrosamines and nitramines potentially generated from amine-based CO2 capture technology
(Journal article; Peer reviewed, 2018-03)Nitrosamines (NSAs) and nitramines (NAs) are identified as possible degradation products from amine-based post-combustion CO2-capture (PCCC). Selected NSAs and NAs were subjected to aerobic and anaerobic biodegradation ... -
Dispersibility and biotransformation of oils with different properties in seawater
(Journal article; Peer reviewed, 2018-01)Dispersants are used to remove oils slicks from sea surfaces and to generate small oil-droplet dispersions, which may result in enhanced biodegradation of the oil. In this study, dispersibility and biodegradation of ... -
Microbial communities in seawater from an Arctic and a temperate Norwegian fjord and their potentials for biodegradation of chemically dispersed oil at low seawater temperatures
(Journal article; Peer reviewed, 2018-04)Biodegradation of chemically dispersed oil at low temperature (0–2 °C) was compared in natural seawater from Arctic (Svalbard) and a temperate (Norway) fjords. The oil was premixed with a dispersant (Corexit 9500) and ... -
Microbial community and metagenome dynamics during biodegradation of dispersed oil reveals potential key-players in cold Norwegian seawater
(Journal article; Peer reviewed, 2018-04)Oil biodegradation as a weathering process has been extensively investigated over the years, especially after the Deepwater Horizon blowout. In this study, we performed microcosm experiments at 5 °C with chemically dispersed ... -
Petroleum hydrocarbon and microbial community structure successions in marine oil-related aggregates associated with diatoms relevant for Arctic conditions
(Journal article; Peer reviewed, 2018-10)Oil-related aggregates (ORAs) may contribute to the fate of oil spilled offshore. However, our understanding about the impact of diatoms and associated bacteria involved in the formation of ORAs and the fate of oil compounds ...
