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 ...
