  1. 1. If Trees Could Talk - Dendrochemistry, a Promising Method for Understanding Pollution History

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Jonatan Uusitalo; [2023-08-17]
    Nyckelord :;

    Sammanfattning : Heavy metal pollution presents a significant environmental challenge in the Anthropocene era, and understanding pollution history is crucial to address historical pollution and implementing effective mitigation measures. This study stands among a few comprehensive dendrochemical investigations that utilized an extensive dataset and energy dispersive X-ray fluorescence (EDXRF) technique to reconstruct the contamination history of As, Cd, Cu, Ni, Pb, and Zn, with a focus on Cu.

  3. 2. Investigation of unknown groundwater flows to two leachate ponds at Hovgården

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Katja Nordström; [2023]
    Nyckelord :landfill; leachate; principle component analysis; PCA; polishing pond;

    Sammanfattning : The leaching of groundwater into two polishing ponds, the last step in the wastewater treatment process on Hovgarden waste facility, was examined. The focus of this study was to analyse the PFAS composition profile (fingerprint) to trace the leaching groundwater. LÄS MER

  4. 3. The geochemical status of the surface water and the sediments in the estuary of the Sangis River, Kalix, Sweden

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Anton Sandberg; [2023]
    Nyckelord :Framboidal pyrite; dredging; Sangis River; estuary; redox ladder; sediment; sediment cores; SEM-EDS;

    Sammanfattning : It has been common in forestry and agriculture to drain waterlogged areas through ditching in order to cultivate them. The ditches that drain water are usually connected to some watercourse, such as a river. LÄS MER

  5. 4. Analysis of the water quality dynamics of Lake Vomb; Interactions between water quality profile and cyanobacterial bloom in a eutrophic lake in Sweden

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Wiebke Coenen; [2022]
    Nyckelord :Vombsj¨on; Lake profile; Cyanobacteria; Drinking water; Random Forest; Technology and Engineering;

    Sammanfattning : Lake Vomb, located in Sk˚ane, Sweden, provides water for groundwater infiltration, used for the drinking water supply of several municipalities, including Malm¨o. The lake is in a bad ecological condition with intense algae blooms during summer. Cyanobacteria dominate mentioned blooms in 2021 posing the threat of releasing cyanotoxins. LÄS MER

  7. 5. Effect of High-Pressure Homogenization and Heat Treatment on the Emulsification Properties of Oat Protein Concentrate

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Annette Kägu; [2022]
    Nyckelord :oat proteins; high-pressure homogenisation; emulsions; food technology; Technology and Engineering;

    Sammanfattning : This master thesis project was performed in collaboration with an agricultural cooperative Lantmännen Oats AB, who has developed a dry protein powder concentrate PrOatein™. The powder consists of oat proteins, dextrins, lipids and β-glucans. LÄS MER
