Biologiske prosesser i sedimenter – en litteraturstudie
Briseid, Tormod; Eek, Espen; Linjordet, Roar (Bioforsk Rapport, Research report, 2006)På bakgrunn av St. meld. nr. 12 ”Rent og rikt hav”, hvor forurensede sedimenter i kyst og fjordområder fikk stor oppmerksomhet, er det nå planlagt en rekke tiltak langs norskekysten. Enkelte av tiltakene innebærer at ... -
CCS Leakage Detection Technology - Industry Needs, Government Regulations, and Sensor Performance
Waarum, Ivar-Kristian; Blomberg, Ann Elisabeth Albright; Eek, Espen; Brown, Jock; Ulfsnes, Amund; Carpenter, Mike; Grimsrud, Torleiv S.; Park, Joonsang; Cornelissen, Gerard; Sparrevik, Per (Peer reviewed; Journal article, 2017)Reliable CCS monitoring is vital in order to confirm that injected CO2 stays in the reservoir as intended, and that any occurring leakage is promptly detected allowing corrective actions to be initiated. Motivations for ... -
Formation and availability of methylmercury in mercury-contaminated sediment: effects of activated carbon and biochar amendments
Sørmo, Erlend; Silvani, Ludovica; Braaten, Hans Fredrik Veiteberg; Bryntesen, Tina; Eek, Espen; Cornelissen, Gerard (Peer reviewed; Journal article, 2022)Purpose As the formation of toxic and bioaccumulative methylmercury (MeHg) in Hg-contaminated sediments is of great concern worldwide, suitable remediation options are needed. Activated carbon (AC) amendment is a contested ... -
Hvordan kan erfaringene med tiltak mot forurensede sedimenter komme mineralindustrien til nytte?
Eek, Espen; Breedveld, Gijs D.; Kibsgaard, Anne (Peer reviewed; Journal article, 2013) -
In situ benthic flow-through chambers to determine sediment-to-water fluxes of legacy hydrophobic organic contaminants
Mustajärvi, Lukas; Eek, Espen; Cornelissen, Gerard; Eriksson-Wiklund, Ann-Kristin; Undeman, Emma; Sobek, Anna (Peer reviewed; Journal article, 2017)Contaminated sediment can release hydrophobic organic contaminants (HOCs) and thereby act as a secondary source of primarily legacy hazardous substances to the water column. There is therefore a need for assessments of the ... -
In situ sediment treatment using activated carbon: A demonstrated sediment cleanup technology
Patmont, Clayton R.; Ghosh, Upal; LaRosa, Paul; Menzie, Charles A.; Luthy, Richard G.; Greenberg, Marc S.; Cornelissen, Gerard; Eek, Espen; Collins, John; Hull, John; Hjartland, Tore; Glaza, Edward; Bleiler, John; Quadrini, James (Journal article, 2015)This paper reviews general approaches for applying activated carbon (AC) amendments as an in situ sediment treatment remedy. In situ sediment treatment involves targeted placement of amendments using installation options ... -
Long-term effects of thin layer capping in the Grenland fjords, Norway: Reduced uptake of dioxins in passive samplers and sediment-dwelling organisms
Schaanning, Morten Thorne; Beylich, Bjørnar; Gunnarsson, Jonas S; Eek, Espen (Peer reviewed; Journal article, 2020)The Grenlandfjords in South East Norway are severely contaminated with dioxins from a magnesium smelter operated between 1950 and 2001. In 2009, the proposal of thin-layer capping as a potential mitigation method to reduce ... -

Monitoring alkylphenols in water using the polar organic chemical integrative sampler (POCIS): Determining sampling rates via the extraction of PES membranes and Oasis beads
Silvani, Ludovica; Riccardi, Carmela; Eek, Espen; Papini, Marco Petrangeli; Morin, Nicolas; Cornelissen, Gerard; Oen, Amy M P; Hale, Sarah (Peer reviewed; Journal article, 2017)Polar organic chemical integrative samplers (POCIS) have previously been used to monitor alkylphenol (AP) contamination in water and produced water. However, only the sorbent receiving phase of the POCIS (Oasis beads) is ... -
Stability of the Gunneklev Fjord sediments
Le, Thi Minh Hue; Rønning, Sigbjørn; Moseid, Mari; Lacasse, Suzanne; Eek, Espen (Peer reviewed; Journal article, 2021)The seabed of the Gunneklev Fjord, with exceptionally soft contaminated sediment, is to be capped.
