  1. 1. Phytoremediation of mercury by terrestrial plants

    Författare :Yaodong Wang; Maria Greger; Lena Kautsky; Douglas Godbold; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phytoremediation; phytoextraction; phytostabilization; bioavailability; willow; Hg; Plant physiology; Växtfysiologi;

    Sammanfattning : Mercury (Hg) pollution is a global environmental problem. Numerous Hg-contaminated sites exist in the world and new techniques for remediation are urgently needed. LÄS MER

  3. 2. Mechanisms behind pH changes by plant roots and shoots caused by elevated concentration of toxic elements

    Författare :Muhammad Tariq Javed; Maria Greger; Sylvia Lindberg; Marinus L. Otte; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Elodea canadensis; Eriophorum angustifolium; fluorescence microscopy; mechanisms; metals and metalloid; pH changes; protoplasts; phytofiltration; phytostabilization; root exudates; Plant Physiology; växtfysiologi;

    Sammanfattning : Toxic elements are present in polluted water from mines, industrial outlets, storm water etc. Wetland plants take up toxic elements and increase the pH of the medium. In this thesis was investigated how the shoots of submerged plants and roots of emergent plants affected the pH of the surrounding water in the presence of free toxic ions. LÄS MER

  4. 3. Phytostabilization of mine tailings covered with fly ash and sewage sludge

    Författare :Clara Neuschütz; Maria Greger; Lena Kautsky; Anthony R. Dexter; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ammonium; biosolids; cadmium; copper; energy crop; metal and nutrient leakage; nitrate; phosphate; phytoremediation; plant stress response; root exudates; zinc; Plant physiology; Växtfysiologi; växtfysiologi; Plant Physiology;

    Sammanfattning : Establishing plant communities is essential for the restoration of contaminated land. As potential cover materials, fly ash and sewage sludge can prevent formation of acid mine drainage from sulfidic mine waste. LÄS MER
