  2. 11. Extent and limitations of functional redundancy among bacterial communities towards dissolved organic matter

    Author : Martin Andersson; Eva Lindström; Stuart Jones; Uppsala universitet; []
    Keywords : Dissolved organic matter; BCC; biodiversity; functional redundancy; Mikrobiologi; Microbiology;

    Abstract : One of the key processes in the carbon cycle on our planet is the degradation of dissolved organic matter (DOM) in aquatic environments. The use of organic matter by bacteria links energy from DOM to higher trophic levels of the ecosystem when bacteria are consumed by other organisms. This is referred to as the microbial loop.

  4. 12. 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

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

    Author : Sara Ekström; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brownification; freshwater; water color; dissolved organic matter DOM ; iron Fe ; decreasing acidification; climate change;

    Abstract : 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. READ MORE

  6. 14. Applications of natural organic matter optical properties for assessing drinking water disinfection and distribution

    Author : Masoumeh Heibati; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; assimilable organic carbon.; Optical properties; disinfection by-products; drinking water; UV disinfection; dissolved organic matter; distribution network;

    Abstract : The task of providing safe drinking water requires proper monitoring of water quality and treatment performance from source to tap. Accordingly, the demand for online monitoring is increasing both at treatment plants a nd within distribution networks. READ MORE

  7. 15. Enrichment of biogenic and anthropogenic organic substances on sea spray aerosols

    Author : Nikola Radoman; Ian Cousins; Matthew Salter; Jurgita Ovadnevaite; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sea spray; Organic carbon; Dissolved organic matter; Phytoplankton bloom; Cationic surfactants; Perfluorinated alkyl acids; LC-MS; HRMS; Analytical Chemistry; analytisk kemi;

    Abstract : The world’s oceans are the source of one of the most abundant types of natural aerosols, namely sea spray aerosols (SSA). By scattering solar radiation, SSA play a significant role in controlling the Earth’s radiation budget, while they are also involved in the formation of clouds, acting as cloud condensation nuclei (CCN).
