  2. 16. Dissolved organic matter across terrestrial and aquatic systems : sources, chemistry and microbial processing

    Author : Geert Hensgens; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dissolved organic matter; carbon; leaching; decay; chemistry; terrestrial; aquatic;

    Abstract : The movement of DOM from terrestrial to aquatic systems is a globally significant flux affecting both carbon sequestration and CO2 emissions. Here, DOM dynamics were investigated in terrestrial and aquatic systems within the context of this carbon flux. READ MORE

  4. 17. Effects of solar radiation on the abiotic and bacterially mediated carbon flux in aquatic ecosystems

    Author : Alexandre Magno Anesio; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bacteria; dissolved inorganic carbon DIC ; bioavailability; aquatic macrophytes; photooxidation; detritus decomposition; Ultraviolet radiation; dissolved organic carbon DOC ; fungi; Hydrobiology; marine biology; aquatic ecology; limnology; Marinbiologi; limnologi; akvatisk ekologi;

    Abstract : In this Thesis, I studied some of the current aspects of organic matter photochemistry. I analyzed abiotic phototransformations of several types of dissolved (DOM) and particulate organic matter (POM). I also evaluated the effects of phototransformation of several types of DOM on bacteria. READ MORE

  5. 18. 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

  6. 19. Tracking changes in dissolved natural organic matter composition : evaluating drinking water production using optical and molecular level tools

    Author : Elin Lavonen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : During the last decades, the abundance of dissolved organic matter (DOM), a complex heterogeneous mixture of organic compounds, has increased in many surface waters in Northern Europe and North America. Surface waters are widely used as raw water sources for drinking water production. READ MORE

  7. 20. Assessing and optimizing biofilter performance in drinking water treatment

    Author : Nashita Moona; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; full-scale biofilters; sterilization.; optical properties; Biofilter; dissolved organic matter; treatment optimization; drinking water;

    Abstract : Biological filtration is a widely used treatment barrier in drinking water treatment plants to ensure the biological stability of treated water in distribution systems. Biofilters remove particulate and dissolved organic matter (DOM) and biodegradable organic matter from water. READ MORE
