  1. 1. THE FIRST ACTIVE ACID SULFATE SOIL FOUND OUTSIDE THE BALTIC BASIN, IN VISKA VALLEY WEST COAST OF SWEDEN

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Johanna Bergström; [2023-09-15]
    Nyckelord :Acid sulfate soil; AS soil; ERT measurements; resistivity; Baltic basin; Swedish west coast; acidification; Tapes transgression;

    Sammanfattning : Acid sulfate (AS) soils are naturally formed but are responsible for environmental problem due to its low pH. Drainage of active AS soils can lead to mobilization of harmful metals and a severe pH drop in nearby aquatic environments, which in turn may harm the ecological conditions. LÄS MER

  3. 2. Long-Term Impact of Drought on AcidSulfate Soil Leaching, a Study of NineCatchment Areas in Sweden and Finland

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Emilie Åström; [2022]
    Nyckelord :acid sulfate soil; hydrological drought; water chemistry; metal leaching; sulfate concentration; sur sulfatjord; hydrologisk torka; vattenkemi; metallurlakning; sulfatkoncentration;

    Sammanfattning : Sediments rich in sulfide were deposited in the Littorina sea in an environment that was shallow, anoxic,and reductive. The sediments were brought above sea level by isostatic uplift and can now be foundalong the coast of the Baltic sea. LÄS MER

  4. 3. 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

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

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

    Sammanfattning : 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.

  5. 4. Coffee grounds as an adsorbent for heavy metals in water treatment : Study based on the environment around Vattenriket, Kristianstad

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Författare :Johan Matson; [2020]
    Nyckelord :Acid sulfate soil; ASS; Adsorption; calcium; coffee residues; exhausted coffee; grounded coffee; pH; total organic carbon; TOC; Vattenriket; Kristianstad; pH; zinc.;

    Sammanfattning : One of the modern times worst environmental problem are polluted water resources. An example of source of pollution to water resources are, heavy metal leached from acid sulfate soils (ASS). LÄS MER

  7. 5. Undersökning av mängden organiskt kol i ett område med sura sulfatjordar i Kristianstads kommun

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Författare :Thérese Lindquist; [2019]
    Nyckelord :Total organic carbon; dissloved organic carbon; pH; distribution pattern; acid sulfate soil; agricultural land; drainage; ditch system; Totalt organiskt kol; löst organiskt kol; pH; fördelningsmönster; sur sulfatjord; jordbruksmark; dränering; dikessystem;

    Sammanfattning : I Fredriksdalsvikens naturreservat i Kristianstads kommun skedde omfattande metalläckage efter en översvämning sommaren 2007 som orsakade skador på djur- och växtliv. De kraftiga metalläckagen misstänks härledas till sura sulfatjordar. LÄS MER
