  1. 1. Regional Nutrient Budgets in Forest Soils in a Policy Perspective

    Detta är en avhandling från Department of Chemical Engineering, Lund University

    Författare :Cecilia Akselsson; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; geomorphology; Physical geography; Miljökemi; Environmental chemistry; skogsteknik; skogsbruk; Skogsvetenskap; forestry technology; forestry; Silviculture; Näringslära; Nutrition; Växtekologi; policy-making; Plant ecology; regional scale; deposition; eutrophication; carbon sequestration; acidification; Nutrient budget;

    Sammanfattning : Sweden's forests are one of its most important natural resources, as well as being important from ecological and social perspectives. Nutrient sustainability is essential to maintain the production capacity and reduce the effects of acidification and eutrophication. LÄS MER

  2. 2. Brownification of freshwaters - the role of dissolved organic matter and iron

    Detta är en avhandling från Department of Biology, Lund University

    Författare :Sara Ekström; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Brownification; freshwater; water color; dissolved organic matter DOM ; iron Fe ; decreasing acidification; climate change;

    Sammanfattning : The term brownification refers to the trend of increasing water color, i.e. the water becoming browner, which has been observed throughout the northern hemisphere over the last decades. Brownification has both ecological and societal implications. LÄS MER

  3. 3. The influence of soil pH on plant and microbial communities in sandy grasslands

    Detta är en avhandling från Department of Biology, Lund University

    Författare :Linda-Maria Mårtensson; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; in situ 13CO2 labelling; disturbance; sandy grasslands; species diversity; acidification; soil pH; microbial biomass; C allocation;

    Sammanfattning : Sandy, calcareous grasslands are species rich temperate semi-natural grasslands. The species composition in 136 plots was analysed in relation to soil chemistry parameters; extractable P and N, soil pH and lime content. LÄS MER

  4. 4. Air Pollution Dependency on Climate Variability and Source Region : Past, Current and Future Air Pollution Scenarios over Europe

    Detta är en avhandling från Stockholm : Department of Applied Environmental Science (ITM), Stockholm University

    Författare :Camilla Andersson; Hans-Christen Hansson; Christer Johansson; Joakim Langner; David Simpson; Peter Builtjes; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acidification; Air Pollution; Climate Change; Europe; Numerical Model; Emission; Eutrophication; Key region; Nitrogen Dioxide; Particulate Matter; PM; Source region; Surface Ozone; Tropospheric Ozone; NATURAL SCIENCES Earth sciences; NATURVETENSKAP Geovetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The main objectives of this thesis were to investigate the dependency of European air pollution on climate variability and emission source region. Calculations with a chemistry transport model (CTM) were conducted to investigate the influence of climate variability. LÄS MER

  5. 5. On the origin of organohalogens found in the environment

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Gunilla Öberg (fd Asplund); [1992]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The natural production of halogenated organic compounds in the environment is often assumed to be negligible compared to the anthropogenic production of such compounds. A change in this general view is advocated in the present thesis. LÄS MER
