   Sammanfattning : Metal contaminated stormwater, i.e. surface runoff in urban areas, can be treated in percolation systems, ponds, or wetlands to prevent the release of metals into receiving waters. Plants in such systems can, for example, attenuate water flow, bind sediment, and directly accumulate metals. LÄS MER

3. 2. 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.
