Benthic community status and mobilization of Ni, Cu and Co at abandoned sea deposits for mine tailings in SW Norway
Schaanning, Morten Thorne; Trannum, Hilde Cecilie; Øxnevad, Sigurd; Ndungu, Kuria (Journal article; Peer reviewed, 2019)During 1960–94 tailings from an ilmenite mine in southwest Norway were placed in sea deposits in a sheltered fjord and a more exposed coastal basin. In 2015 both deposit sites were sampled to assess the state of metal ... -
Bioaccumulation and trophic transfer of cyclic volatile methylsiloxanes (cVMS) in the aquatic marine food webs of the Oslofjord, Norway
Powell, David E; Schøyen, Merete; Øxnevad, Sigurd; Gerhards, Reinhard; Böhmer, Thomas; Koerner, Martin; Durham, Jeremy; Huff, Darren (Journal article; Peer reviewed, 2018)The trophic transfer of cyclic methylsiloxanes (cVMS) in aquatic ecosystems is an important criterion for assessing bioaccumulation and ecological risk. Bioaccumulation and trophic transfer of cVMS, specifically ... -
The ecotoxicology of marine tributyltin (TBT) hotspots: A review
Beyer, Jonny; Song, You; Tollefsen, Knut-Erik; Berge, John Arthur; Tveiten, Lise Ann; Helland, Aud; Øxnevad, Sigurd; Schøyen, Merete (Peer reviewed; Journal article, 2022)Tributyltin (TBT) was widely used as a highly efficient biocide in antifouling paints for ship and boat hulls. Eventually, TBT containing paints became globally banned when TBT was found to cause widespread contamination ... -
In vivo bioaccumulation of contaminants from historically polluted sediments - Relation to bioavailability estimates
Ruus, Anders; Allan, Ian; Øxnevad, Sigurd; Schaanning, Morten; Borgå, Katrine; Bakke, Torgeir Heggelund; Næs, Kristoffer (Journal article; Peer reviewed, 2013)Many contaminants are recalcitrant against degradation. Therefore, when primary sources have been discontinued, contaminated sediments often function as important secondary pollution sources. Since the management and ... -
Levels and trends of tributyltin (TBT) and imposex in dogwhelk (Nucella lapillus) along the Norwegian coastline from 1991 to 2017
Schøyen, Merete; Green, Norman W; Hjermann, Dag Ø; Tveiten, Lise Ann; Beylich, Bjørnar; Øxnevad, Sigurd; Beyer, Jonny (Journal article; Peer reviewed, 2019)The banning of organotin biocides, such as tributyltin (TBT), from use in marine antifouling paints is now leading to reproductive health recovery in marine gastropod populations all over the world. TBT induces socalled ... -
Mercury concentration trend as a possible result of changes in cod population demography
Ruus, Anders; Hjermann, Dag Øystein; Beylich, Bjørnar; Schøyen, Merete; Øxnevad, Sigurd; Green, Norman Whitaker (Journal article; Peer reviewed, 2017)Mercury (Hg) in Atlantic cod (Gadus morhua) is one of many parameters that are monitored through OSPAR's Joint Assessment and Monitoring Programme. Time series for cod in the Inner Oslofjord (Norway) go back to 1984. Until ... -
Petroleum oil and mercury pollution from shipwrecks in Norwegian coastal waters
Ndungu, Kuria; Beylich, Bjørnar; Staalstrøm, Andre; Øxnevad, Sigurd; Berge, John A; Braaten, Hans Fredrik Veiteberg; Schaanning, Morten; Bergstrøm, Rune (Journal article; Peer reviewed, 2017)Worldwide there are tens of thousands of sunken shipwrecks lying on the coastal seabed. These potentially polluting wrecks (PPW) are estimated to hold 3–25 million t of oil. Other hazardous cargo in PPW includes ordnance, ...
