  1. 1. Emission of greenhouse gases from constructed wetlands : Nutrient status in relation to methane and nitrous oxide emission

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Christian Lundström; [2022]
    Keywords : Constructed wetland; greenhouse gas emission; nutrient status; ebullition; Anlagd våtmark; växthusgasutsläpp; näringsstatus; ebullition;

    Abstract : Agricultural land releases large amounts of nitrogen and phosphorus to water bodies which causes eutrophication. Creating wetlands on agricultural land is one way to prevent this major issue. However, constructed wetlands are a large emission source of greenhouse gases. READ MORE

  3. 2. Biokol som tillsats i vallensilage utfodrat till mjölkraskvigor : inverkan på konsumtionsförmåga, smältbarhet, träckens konsistens och färg, samt djurens renhet

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Ida Milton; [2022]
    Keywords : Biokol; Smältbarhet; Vallensilage; Aktivt kol; Mjölkraskvigor; Konsumtionsförmåga; Träckkonsistens; Färg; Renhet;

    Abstract : Biokol är en produkt som tillverkas av organiskt material eller biomassa i en process som kallas pyrolys, då materialet upphettas i en temperatur från 350 till 1000 ̊C i en syrefri miljö. Biokol är lagringsstabil under lång tid innan den bryts ned och fungerar därför som kolsänka. READ MORE

  4. 3. Long-Term Impact of Drought on AcidSulfate Soil Leaching, a Study of NineCatchment Areas in Sweden and Finland

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Emilie Åström; [2022]
    Keywords : acid sulfate soil; hydrological drought; water chemistry; metal leaching; sulfate concentration; sur sulfatjord; hydrologisk torka; vattenkemi; metallurlakning; sulfatkoncentration;

    Abstract : Sediments rich in sulfide were deposited in the Littorina sea in an environment that was shallow, anoxic,and reductive. The sediments were brought above sea level by isostatic uplift and can now be foundalong the coast of the Baltic sea. READ MORE

  5. 4. Drivers of decomposition across Sphagnum bog margins

    University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Author : Emil Nordström; [2022]
    Keywords : Peatlands; tea bag index; edge effects; carbon storage; carbon sequestration; waterlogging; Torvmark; kanteffekter; kollagring; koldioxidbindning;

    Abstract : Peatlands provide multiple ecosystem services, including extensive carbon sequestration and storage, yet many peatlands have been degraded or destroyed. Peatlands carbon storage capacity is connected to inherently low decomposition rates, causing the build-up of organic matter.

  6. 5. Identification and quantification ofmicrobiological risks in board production : A study of ATP bioluminescence and redox potential

    University essay from Karlstads universitet/Avdelningen för kemiteknik

    Author : Claudia Bartos; [2022]
    Keywords : ATP bioluminescense; redox potential; bacillus; board production;

    Abstract : Stora Enso is a well-established provider of renewable solution packaging and board materials.Board products for liquid packaging and folding cartons for food are particularly sensitive tothe microbiological contaminants. In the manufacturing process, microbiological growth occursdue to environmental favourable conditions. READ MORE
