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 ... -
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 ... -
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 ... -
The influence of permanently submerged macrophytes on sediment mercury distribution, mobility and methylation potential in a brackish Norwegian fjord
Olsen, Marianne; Schaanning, Morten; Braaten, Hans Fredrik Veiteberg; Eek, Espen; Moy, Frithjof Emil; Lydersen, Espen (Peer reviewed; Journal article, 2018)Macrophytes are shown to affect the microbial activity in different aqueous environments, with an altering of the sediment cycling of mercury (Hg) as a potential effect. Here, we investigated how a meadow with permanently ... -
Use of life cycle assessments to evaluate the environmental footprint of contaminated sediment remediation
Sparrevik, Lars Magnus; Saloranta, Tuomo; Cornelissen, Gerard; Eek, Espen; Fet, Annik Magerholm; Breedveld, Gijs D.; Linkov, Igor (Peer reviewed, 2011)
