Impaired benthic macrofauna function 4 years after sediment capping with activated carbon in the Grenland fjords, Norway
Raymond, Caroline; Samuelsson, Göran S.; Agrenius, Stefan; Schaanning, Morten T; Gunnarsson, Jonas S. (Peer reviewed; Journal article, 2021)The sediments in the Grenland fjords in southern Norway are heavily contaminated by large emissions of dioxins and mercury from historic industrial activities. As a possible in situ remediation option, thin-layer sediment ... -
Response of marine benthic fauna to thin-layer capping with activated carbon in a large-scale field experiment in the Grenland fjords, Norway
Samuelsson, Göran S.; Raymond, Caroline; Agrenius, Stefan; Schaanning, Morten; Cornelissen, Gerard; Gunnarsson, Jonas S. (Journal article; Peer reviewed, 2017)A field experiment with thin-layer capping was conducted in the Grenland fjords, Norway, for remediation in situ of mercury and dioxin-contaminated sediments. Experimental fields at 30 and 95 m depth were capped with (i) ... -
