  1. 1. Effects of vegetation and nutrients on methanotroph abundance and methane emissions from constructed wetlands

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

    Författare :Klara Yngve; [2022]
    Nyckelord :Diffusive flux; Ebullition; Dissolved CH4; CH4 oxidation; Phosphorous;

    Sammanfattning : Agriculture is the largest anthropogenic source of nitrogen and phosphorous (P) leakage to Swedish coastal seas, causing eutrophication which threatens marine ecosystems. Constructing wetlands is one way to improve nutrient retention in the modern agricultural landscape. However, constructed wetlands can emit substantial amounts of methane (CH4). LÄS MER

  3. 2. Phosphorous Precipitation in Source Separated Greywater for Direct Environmental Release.

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Ashley Hall; [2022]
    Nyckelord :water; wastewater; source separation; greywater; phosphorous; precipitation; utfällning; Chemical Engineering; Technology and Engineering;

    Sammanfattning : As our understanding of the impact humans have on the environment changes, so too do the mitigation strategies we employ to prevent it. One major source of anthropogenic pollution is wastewater effluent. LÄS MER

  4. 3. Möjligheter och hinder för att skörda  uppspolade alger och sjögräs på  Gotland

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

    Författare :Kristina Reichelova; Josefine Sjödin; [2022]
    Nyckelord :Beach wrack; Beach cast; Beach wrack harvesting; Obstacles; Gotland; Släke; Släkeskörd; Hinder; Gotland;

    Sammanfattning : En av de största utmaningarna för Östersjöregionen gäller bekämpningen av övergödning orsakad av människors utsläpp av näringsämnen till havet. Övergödningen har flera allvarliga konsekvenser för miljön, inte minst enorma algblomningar samt stora mängder alger och tång som så småningom spolas upp längs Östersjöns stränder och börjar förmultna.

  5. 4. Improving mussel reef protection from a sustainability perspective: Mapping of a blue mussel reef in Denmark

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Lydia Alexandra Ness; [2022]
    Nyckelord :Sustainable Development; biogenic reef; blue mussels; ROV; mapping; habitat protection; earth sciences;

    Sammanfattning : Coastal areas currently face a lot of anthropogenic pressures (Erlandsson et al, 2011; Wilcox et al, 2020) which might further increase through climate change (Maltby et al, 2022). This can lead to the disappearance of crucial, habitat engineering species like blue mussels (Tummon Flynn et al, 2020). LÄS MER

  7. 5. Long-term phosphorus trends in Swedish rivers and streams : widespread and persistent nutrient decline

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

    Författare :Sara Camiolo; [2021]
    Nyckelord :eutrophication; rivers; streams; phosphorus;

    Sammanfattning : Phosphorus (P) is often considered the limiting nutrient for freshwater productivity because of its relevant role in regulating algal production and determining community composition. The concern for increasing anthropogenic P inputs registered since the last century has shaped environmental policies around the world to limit the effects of algal bloom (also known as eutrophication) in freshwater ecosystems through the establishment of maximum threshold nutrient concentrations.
