  2. 1. Fractionation of Cu and Fe isotopes in metal-rich mine sites : biotic and abiotic processes

    Author : Nathalie Pérez Rodríguez; Magnus Land; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cu and Fe isotopes; fractionation; tailings; plants; phytoremediation; organic amendments; soil bacteria; Cu and Fe cycle; covellite; redox processes; Applied Geology; Tillämpad geologi;

    Abstract : After mineral exploitation the residual grinded and milled material, rich in sulphide minerals and heavy metals, is often left exposed to the atmospheric variables. This weathered mine waste material can lead to the formation of acid mine drainage (AMD) which has negative effects to the environment. READ MORE

    Abstract : Persistent organic pollutants (POPs) are hydrophobic substances that readily sorb to organic matter in particles and colloids instead of being freely dissolved in the water phase. This sorption affects the bio­availability and environmental transport of the POPs. READ MORE

  6. 4. Role of soil organic matter for immobilisation of metals : treatment of leachate from MSWI bottom ashes

    Author : Jurate Kumpiene; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : In this thesis, the focus is laid on the ability of natural organic matter (OM) to serve as a metal stabilising agent. The metal contaminants investigated arise from the MSWI bottom ash leachate. Besides the high content of metals, elevated pH and salinity are characteristic for ash leachate that, in turn, can alter the functionality of OM. READ MORE

  7. 5. Effects of Bio-Ash Amendments on the Metabolism of Ectomycorrhizal Fungi : A Method Development and Metabolomic Study

    Author : Ana Paola Vilches; Dan Bylund; Sara Norström; Bjarne Strobel; Mittuniversitetet; []
    Keywords : ;

    Abstract : Forest ecosystems have played a fundamental role in the development of our society. Since the beginning of the civilization, forest have provided us with wood as a product for construction, tools, furniture and domestic heating. The well-being of the forest is therefore fundamental to our existence. READ MORE
