    Abstract : The objective of this thesis was to quantify differences between adjacent patches with and without ground flora of Deschampsia flexuosa L. Trin or Anemone nemorosa L. in two acid European beech (Fagus sylvatica L.) forest floors in south-west of Sweden. READ MORE

  4. 2. Generation of Leachate and the Flow Regime in Landfills

    Author : David Bendz; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; teknisk geologi; Hydrogeologi; geographical and geological engineering; Hydrogeology; model; transport; flow; leachate; water; hydrology; landfill; MSW; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : The environmental impacts of landfills are associated mainly with the emission of leachate and biogas. Sanitary landfilling aims to stabilize the landfill in a efficient and controlled way, so that the environmental impacts are minimized. When a sanitary landfill has attained its final storage quality, it can be integrated into the environment. READ MORE

  5. 3. Microbial remediation of heavy metal ion polluted soil and water

    Author : Torbjörn Håkansson; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EDTA; metal; soil; remediation; Sulphate reducing bactera; biogas; water;

    Abstract : Contamination of soil and water by heavy metal ions (HMs) is a problem all over the world.The use of biological methods alone or in combination with other techniques for treatment of such polluted sites constitutes a major challenge. 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
