Acute and long-term effects of anionic polyacrylamide (APAM) on different developmental stages of two marine copepod species
(Journal article; Peer reviewed, 2020-10)The application of synthetic polymers such as anionic polyacrylamides (APAM) in enhanced oil recovery (EOR) may increase in the future. This can lead to environmental release through offshore produced water discharges with ... -
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 oil spill dispersant surfactants in cold seawater
(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 ... -
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 ... -
Characterisation of fine-grained tailings from a marble processing plant and their acute effects on the copepod Calanus finmarchicus
(Journal article; Peer reviewed, 2017)Submarine tailing disposal (STD) of mining waste is practiced as an alternative to land fill disposal in several countries. Knowledge of the environmental implications of STD on fjord and other marine ecosystems, including ... -
Climate change mitigation effects: How do potential CO2 leaks from a sub-seabed storage site in the Norwegian Sea affect Astarte sp. bivalves?
(Peer reviewed; Journal article, 2021)Carbon capture and storage (CCS) is one of the most promising mitigation strategies for reducing the emissions of carbon dioxide (CO2) to the atmosphere and may substantially help to decelerate global warming. There is an ... -
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 ... -
Dispersibility and dispersion stability of carbon nanotubes in synthetic aquatic growth media and natural freshwater
(Journal article; Peer reviewed, 2018-06)The dispersion behavior of carbon nanotubes (CNTs) is influenced by both their physicochemical properties and by the aqueous media properties (e.g. ionic strength, presence of divalent cations and natural organic matter) ... -
Effects of marine mine tailing exposure on the development, growth, and lipid accumulation in Calanus finmarchicus
(Peer reviewed; Journal article, 2021)Marine tailing disposal (MTD) is sometimes practiced as an alternative to traditional mine tailing deposition on land. Environmental challenges connected to MTD include spreading of fine particulate matter in the water ... -
Marine microplastic: Preparation of relevant test materials for laboratory assessment of ecosystem impacts
(Journal article; Peer reviewed, 2018-12)Studies investigating the effects of plastic litter on marine biota have almost exclusively utilised pristine plastic materials that are homogeneous in polymer type, size, shape and chemical composition. This is particularly ... -
Modelling biodegradation of crude oil components at low temperatures
(Others, 2020-09)For oil spilled at sea, the main weathering processes are evaporation, emulsification, photo-oxidation, dispersion and biodegradation. Of these, only biodegradation may completely remove hydrocarbons from the environment ...
