  1. 11. Selected PFAS in the water treatment at the waste-to-energy plant in Umeå : Investigating concentration and composition of selected PFAS in different water treatment steps

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Amanda Carlund; [2023]
    Nyckelord :;

    Sammanfattning : The present study investigated the changes in concentration and composition of five selected PFAS substances in the water treatment at the waste-to-energy plant in Umeå. The five PFAS were PFHxA, PFHpA, PFOA, PFHxS and PFOS. As PFAS exists in a variety of consumer products, they will to some extent end up in waste incineration. LÄS MER

    Sammanfattning : Infrastructural projects to realize the energy transition are framed by governmentsfrom all around the world very positively. This is also the case for green hydrogen,which is considered as a silver bullet to solve multiple crises simultaneously. LÄS MER

  4. 13. Sensitivity of Norway Spruce (Picea abies) to inundation.

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Whitney Cleopatra Vlahakis; [2023]
    Nyckelord :Inundation; riparian zone; spruce seedlings; restoration; mortality;

    Sammanfattning : Alteration of river flow regimes due to dams result in modifications of riparian ecosystem, with impacts on vegetation, landforms, and habitats. A key characteristic that differentiates riparian zones from adjacent aquatic and terrestrial environments is the event of periodic flooding and water logging. LÄS MER

  5. 14. Coupling between iron and humic substances in a land-sea transitional zone in the northern Baltic Sea

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Anna Osterman; [2023]
    Nyckelord :Iron; Humic substances; Dissolved organic carbon; Baltic Sea; Rivers;

    Sammanfattning : In marine ecosystems around the world, iron (Fe) is a well-studied and important trace element which has been found to stimulate phytoplankton and cyanobacteria growth, as well as limit nitrogen fixation and being essential for Legionella pneumophila which is known as the main cause of Legionnaires’ disease. Fe also contributes to the brownification of freshwater and has recently been documented to increase in concentration in rivers in Sweden. LÄS MER
