1. 1. 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

3. 2. Phytostabilisation : use of wetland plants to treat mine tailings

   Författare :Eva Stoltz; Maria Greger; Lena Kautsky; Marinus Otte; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phytostabilisation; wetland plants; mine tailings; Plant physiology; Växtfysiologi;

   Sammanfattning : Mine tailings can be rich in sulphide minerals and may form acid mine drainage (AMD) through reaction with atmospheric oxygen and water. AMD contains elevated levels of metals and arsenic (As) that could be harmful to animals and plants. LÄS MER

4. 3. Role of plants in treating metal-polluted waters in wetlands

   Författare :Johanna Nyquist; Maria Greger; Hans Brix; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; treatment wetlands; stormwater; AMD; metal uptake; wetland plants; Biology; Biologi; växtfysiologi; Plant Physiology;

   Sammanfattning : The overall aim of this thesis was to evaluate the role of wetland plants in wetland treatment of metal-polluted waters. The specific aims were to investigate metal uptake in various wetland plant species; whether and how wetland plants tolerate high metal concentrations in their immediate surroundings, and how the pH and metal concentrations of polluted waters influence metal uptake in wetland plants were also investigated.
