An In Situ Experimental Study of Effects on Submerged Vegetation After Activated Carbon Amendment of Legacy Contaminated Sediments
Olsen, Marianne; Moy, Frithjof Emil; Mjelde, Marit; Lydersen, Espen (Journal article; Peer reviewed, 2018)Activated carbon (AC) amendment has been shown to reduce bioavailability of hydrophobic contaminants in the bioactive layer of sediment. Unwanted secondary effects of AC amendment could be particularly undesirable for ... -
The influence of a submerged meadow on uptake and trophic transfer of legacy mercury from contaminated sediment in the food web in a brackish Norwegian fjord
Olsen, Marianne; Fjeld, Eirik; Lydersen, Espen (Journal article; Peer reviewed, 2019)There are contradicting results on the importance of legacy mercury (Hg) contaminated sediments to Hg fish tissue concentrations. Still, sediment remediation actions often aim at minimizing ecosystem exposure and human ... -
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 (Journal article; Peer reviewed, 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 ...
