  4. 2. Arsenic accumulation in plants for food and phytoremediation : Influence by external factors

    Author : Claes Bergqvist; Maria Greger; Sylvia Lindberg; Lena Ma; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arsenic; accumulation; availability; distribution; habitat; phy-toremediation; rhizosphere; redox potential; speciation; Plant Physiology; växtfysiologi;

    Abstract : Arsenic (As) appears in the environment as various As species, which may vary in plant uptake and toxicity. Moreover, As exposure may vary between habitat due to availability and speciation, both of which are influenced by redox potential. To decrease As uptake, addition of silicate may be a tool.

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

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

    Abstract : 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. READ MORE
