  2. 11. Influence of hydrochemical parameters on the mobility and redistribution of metals from a mine waste deposit

    Author : Stefan Karlsson; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : The aim of the research presented in this thesis has been to combine theoretical and empirical methods to describe chemical attenuation of trace metals (i.e. Al, Cd, Cu, Fe, Mn, Pb and Zn) in a polluted watershed. It was possible to elucidate the major mechanisms by using the naturalvariations of chemical composition of the system. READ MORE

  4. 12. Photochemical alterations of dissolved organic matter : Impact on heterotrophic bacteria and carbon cycling in lakes

    Author : Stefan Bertilsson; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Globally, the amount of carbon in dissolved organic matter (DOM) is similar to the total amount in the atmosphere. DOM also plays a key role in structuring natural surface waters and affects the physical, chemical, and biological character of these systems. READ MORE

  5. 13. Judgements in Equilibrium? : An Ethical Analysis of Environmental Impacts Assessment

    Author : Anders Melin; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; environmental ethics; reflective equilibrium; John Rawls; overlapping consensus; environmental politics; environmental impact assessment; miljöetik; miljöpolitik; etik; miljö; naturskydd; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Since the end of the 1960s the questions of what duties current generations owe towards future generations and what duties human beings owe towards natural entities have been increasingly discussed within ethics. A new subdiscipline - environmental ethics - has emerged that especially focuses on these moral issues. READ MORE

  6. 14. Nutrient loads to the Baltic Sea

    Author : Per Stålnacke; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Nutrient enrichment is generally regarded as the greatest threat to the ecosystems of the Baltic Sea. This thesis demonstrates that the loads of nitrogen and phosphorus in the rivers in the Baltic Sea drainage basin are larger than previously assumed and by far exceed the size of the loads that reach the sea by way of other pathways, i.e. READ MORE

  7. 15. Phthalates in landfill leachates : a signature of their degradation: Analytical aspects & toxicological considerations

    Author : Susanne Jonsson; Bo Svensson; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Phthalic acid diesters comprise a large group of organic compounds that are used to manufacture a variety of products all over the world, and this has raised concerns about the fate of these compounds in the environment. The diester-containing products often end up in landfills, where they are degraded by various micro-organisms, which gives rise to transient intermediates such as phthalic acid monoesters and ortho-phthalic acid.
