  1. 11. 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. 12. Development of a Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Josephine Lindsey-Clark; [2021]

  4. 13. Physical microhabitat requirements for Margaritifera margaritifera and the influence of hydro- and morphodynamics on mussel bed stability

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Tove Westberg; [2020]
    Keywords : Stream restoration; Freshwater pearl mussel; Microhabitat requirements; Sediment transport; Mussel translocation;

    Abstract : Margaritifera margaritifera is an endangered freshwater pearl mussel with population declines throughout its Holarctic range. Boulder-bed channels with little input of fine sediment in previously channelized streams are abundant in Sweden. Hence, restoration efforts for M. READ MORE

  5. 14. Temporal and spatial trends of heavy metal leakage from acid sulfate soils : Leakage of Ni, Zn, Cu and Fe to freshwater and marine sediments, North-eastern Sweden

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Bella Blomkvist; [2020]
    Keywords : acid sulfate soils; leaching; Persöfjärden; sulfide oxidation; metal pollution;

    Abstract : Acid Sulfate soils (AS) are recognized for being a source of acidity in freshwaters in America, Europe, Australia, and Asia. Apart from the problematic acid leachate, AS soil serves as a possible source of toxic heavy metals in freshwaters, a problem which has received far less attention than problems related to acid leachate.

  6. 15. Foreland evolution of Blåisen, Norway, over the course of an ablation season

    University essay from Lunds universitet/Geologiska institutionen

    Author : Alexander Hamilton-Foyn; [2020]
    Keywords : Geomorphological Mapping; Structure from Motion; Glacial Landforms; Ice-Marginal Landforms; Landform Preservation; Hardangerjøkulen; Norway; Earth and Environmental Sciences;

    Abstract : This study presents a detailed investigation into the evolution of sedimentary landforms over an ablation season at Blåisen, an outlet of the Hardangerjøkulen Icecap, Norway. The two visits to Blåisen, one each side of the ablation season, allowed the preservation and evolution of the landforms to be studied. READ MORE
