  1. 1. Biochar-based thin-layer capping of contaminated sediment in Burefjärden, northern Sweden : Assessment of biochar mixed into four structural materials for preventing release of trace elements from sediment to water

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Nathalie Pantzare; [2021]
    Keywords : biochar; contaminated sediment; remediation; thin-layer capping;

    Abstract : Coastal areas around the world have been recognized as largely impacted by anthropogenic activities resulting in pollution of marine sediments. In Sweden, surveys conducted along the coastline of the Bothnian Bay have identified a total area of about 29 km2 as fiber rich sediments. READ MORE

  3. 2. Methods for measuring mercury in gas ebullition from fiber banks : A literature study

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Diana Jonsson; [2021]
    Keywords : Fiber bank; fiber rich-sediment; mercury; contaminants; gas ebullition; pulp-fiber; wood industry; paper industry; environmental toxicity; wood waste;

    Abstract : Mercury contamination is an environmental issue with high priority due to its high toxicity. In addition to the atmospheric deposition, several lakes and rivers in Sweden are contaminated as a result from wood and pulp-fiber industries which stretches back 200 years. READ MORE

  4. 3. Site Study of Fibrous Sediments in Sandviken, Ångermanälven River Estuary, Sweden

    University essay from Uppsala universitet/Naturresurser och hållbar utveckling

    Author : Joanna Ghaderidosst; [2020]
    Keywords : Fiberbank; fiber-rich; fibrous sediment; pulp and paper industry; bearing capacity; FluMu; Penetrometer; Pollution; consolidation; gas; Fiberbank; fiberrik; fiberhaltigt sediment; pappersindustri; bärkraft; FluMu; penetrometer; förorening; gas;

    Abstract : Pulp and paper industries in Sweden have since the end of the 19th century until late 70s been active in dumping wastewater into adjacent water bodies that have created fibrous sediments called fiberbank and fiber-rich sediment. Fiberbanks are large banks of predominantly organic material while fiber-rich sediment is fibrous sediment that has been mixed with bottom sediment. READ MORE

  5. 4. Spatial distribution of persistent organic pollutants (POPs) in sediments contaminated by fiber material from pulp and paper industries

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Gabriel Dupaul; [2018]
    Keywords : PCB; DDT; HCB; fiberbank; fiber-rich sediment; sediment; Sweden; Västernorrland; Ångermanälven; Gulf of Bothnia; Baltic sea;

    Abstract : Sweden has had a long history of forestry activities together with pulp and paper operations. Historical discharges of organic-rich wastewater from pulp and paper factories have resulted in formation of large fiberbanks on the seafloor, which lately have been found to be contaminated with persistent organic pollutants (POPs).

  6. 5. Spreading of persistent organic pollutants from fiber bank sediments

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Lisa Vogel; [2015]
    Keywords : persistent organic pollutants; PCB; DDT; HCB; fiber bank; paper and pulp; POM; log Kd; bioaccumulation; pore water concentration; Marenzelleria spp.; Saduria entomon;

    Abstract : Discharge of untreated wastewater from paper and pulp industries have led to large environmental impacts on the coastal sediments in Västernorrland, Sweden. Dissolved fibers caused the formation of large fiber banks and fiber influenced sediment areas, which proved to be highly affected by contamination with persistent organic pollutants (POPs). READ MORE
