  1. 11. Influence of Wastewater DOM Fractions on the Adsorption of Pharmaceuticals onto Activated Carbon

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Koustubh Karande; [2022]
    Keywords : Wastewater treatment; Dissolved organic matter; Pharmaceuticals; Activated carbon; Hydrophobicity; Molecular weight; Water resources engineering; Technology and Engineering;

    Abstract : Micropollutants in our sources of freshwater is an issue which requires immediate attention. The presence of pharmaceuticals, endocrine disrupting agents, pesticides and other harmful compounds have proven to have impact on the aquatic as well as on human life. READ MORE

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

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

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

    Abstract : 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. READ MORE

  4. 13. Effects of plastic pollution on leaf litter decomposition in Swedish freshwater ecosystems : a field study addressing recently and globally emerging pollutants

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Martina Stangl; [2022]
    Keywords : Microplastics; Face masks; Ecosystem functioning; Leaf decomposition; Field study;

    Abstract : Plastic pollution is recognized as an increasing environmental problem, but few studies have addressed impacts on ecosystem functions, and very few have been conducted in the field. This study investigated the effects of polypropylene particles derived from disposable face masks on in-situ leaf litter decomposition processes in freshwater ecosystems. READ MORE

  5. 14. P-cycling in sub-Arctic lakes – the importance of sediment release and retention

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Hanna Ravry; [2022]
    Keywords : phosphorus; sediment; oligotrophication;

    Abstract : Oligotrophication is generally caused by a decreased nutrient availability, usually due to phosphorous limitation. This is a phenomenon impacting the entire food web and at worst causing cascading alterations within an ecosystem. Lakes of the Northern Hemisphere have lately been documented to be subjected to oligotrophication (e.g. READ MORE

  6. 15. How social behaviour in juvenile Brown trout (Salmo trutta) are regulated by social hierarchies and exposure to the benzodiazepine oxazepam

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Elin Johansson Kvarnström; [2022]
    Keywords : Behaviour; Brown trout; Dominance; Ecotoxicology; Exposure; Fish; Oxazepam; Pharmaceutical; Salmo trutta; Social status;

    Abstract : Improved global healthcare rises the production and consumption of human pharmaceuticals. Insufficient wastewater treatment systems and unregulated downstream impacts causes pharmaceutical contamination of surface waters with trace residues in countries covering all continents. READ MORE
