  1. 16. Behavioural effects on Lymnaea stagnalis following sublethal exposure to the antidepressant fluoxetine

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Jennie Hansson; [2021]
    Nyckelord :Ecotoxicology; Lymnaea stagnalis; fluoxetine; SSRI; Toxicity; sub-lethal; dose-response relationship; Earth and Environmental Sciences;

    Sammanfattning : The use of selective serotonin reuptake inhibitors (SSRI), a group of antidepressants, increases globally resulting in higher concentrations also in wastewater recipients. These concentrations may cause altered behaviour of aquatic organisms and have effects on whole ecosystem level. LÄS MER

  3. 17. A two-stage ditch – a source or sinks of nutrients and sediment : evaluation of sediment loss and inundation frequency

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Sheryl Ilao Åström; [2021]
    Nyckelord :Two-stage ditch; geomorphology; inundation frequency; channel evolution; water quality; agricultural ditch;

    Sammanfattning : Human-made channel systems in the agricultural landscape have received critical attention due to the dire consequences on water quality and increasing eutrophication polluting receiving aquatic systems. Trapezoidal-formed (traditional) ditches have been scrutinized and a new mitigation measure for channelized drainage systems has gained a great deal of attention i. LÄS MER

    Sammanfattning : The climate on earth keeps getting warmer where heat waves, eutrophication, rising sea levels, extreme weather like flooding, droughts and wildfires are an expanding problem. The focus of this bachelor thesis is to determine the potential of mitigating eutrophication and while contributing to blue growth by harvesting and make use of reeds like Phragmites australis and Arundo donax.
