Biodegradation-mediated alterations in acute toxicity of water-accommodated fraction and single crude oil components in cold seawater
Brakstad, Odd Gunnar; Størseth, Trond Røvik; Rønsberg, Marianne Unaas; Hansen, Bjørn Henrik (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 ... -
