  1. 1. 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

  3. 2. 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

  4. 3. Gas Emissions from Contaminated Fibrous Sediments in Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Fredrik Collin; [2020]
    Keywords : Fiberbank; fibrous sediment; gas ebullition; GHG emissions; methanogenesis; optical ebullition sensor; Fiberbank; fibersediment; gas ebullition; växthusgas emissioner; metanogenes; optiska ebullitions sensore;

    Abstract : Gas Emissions from Contaminated Fibrous Sediments in Sweden The discharge of untreated wastewater from pulp and paper mills have resulted in the accumulation offibrous sediments on the bottom of many nearby aquatic recipients. Some accumulations are multiplemeters thick and consist almost entirely of cellulose fibre or wood chips; these are called fiberbanks. 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. Submarine slope instability as a cause of contaminated sediment dispersal in Ångermanälven, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Hannes Berg Wiklund; [2015]
    Keywords : Submarine landslides; contaminated sediments; weak layers; Ångermanälven; Undervattenskred; förorenade sediment; svaga lager; Ångermanälven;

    Abstract : This study aims at providing results for the analysis of the stratigraphy underlying contaminated sediments in Ångermanälven. The contaminated sediments, containing heavy metals and persistent organic pollutants, are derived from wastewater discharged into Ångermanälven from nearby paper and pulp industries. READ MORE
