  1. 1. 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

  3. 2. Hydrodynamic and Eutrophication Modelling of Lake Vomb: Impact of Future Climate Change on Cyanobacteria

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Ahmed Elhabashy; [2022]
    Nyckelord :Hydrodynamic modelling; eutrophication; Cyanobacteria; Chlorophyll-a; climate change; MIKE 3 FM; Lake Vomb;

    Sammanfattning : The increasing frequency of Cyanobacterial blooms in freshwater bodies raise concerns around the globe. The consequences of this phenomenon impact not only human health but the entire surrounding ecosystem. During the past decades, numerical modelling has been increasingly used to investigate and study aquatic systems. LÄS MER

  4. 3. Application of data-driven models in exploring cyanobacterial bloom risks in Lake Mälaren

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Abigail Huertas Herrera; [2021]
    Nyckelord :Random Forest; blue-green algae; WHO Alert Level Framework; drinking water supply; cyanobacterial blooms;

    Sammanfattning : Cyanobacteria are a unique organism, a bacterium that develop photosynthesis, thus it contains chlorophyll, a pigment commonly associated to algae. For this reason, cyanobacteria are also known as blue-green algae. One of the secondary metabolites of cyanobacteria is cyanotoxin, a substance which is hepatoxic, neurotoxic, and dermatoxic.

  5. 4. Satellitövervakning av cyanobakterieblomningar i sjöar : en jämförande studie för Mälaren

    Kandidat-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Patrik Hildén; [2021]
    Nyckelord :cyanobakterier; algblomning; klorofyll; fjärranalys; Mälaren;

    Sammanfattning : Cyanobakterieblomningar ökar världen över och orsakar både ekonomiska förluster och hälsorelaterade problem. På grund av cyanobakteriers potentiellt skadliga inverkan sker regelbunden provtagning i svenska vatten. LÄS MER

  7. 5. Fluorescence probes: towards automatic coagulant dosing

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Daphné Lecellier; [2018]
    Nyckelord :Drinking water quality; Water treatment process; Coagulation; Microcystis aerugosa; algal organic matter; LC-OCD; EEM; powdered activated carbon; Alum;

    Sammanfattning : There is a current lack of accurate tools to determine the concentration of cyanobacteria in situ.  Besides, cyanobacterial blooms have to be carefully monitored in reservoirs as they are more frequent because of climate change and can lead to potential released of toxins, along with other components.
