  1. 1. Högfrekventa mätningar med sensorer för transportberäkning av totalfosfor i vattendrag

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

    Author : Nora Ottander; [2020]
    Keywords : turbiditet; fosfor; sensor; transportberäkning; övergödning;

    Abstract : Large areas in the Baltic Sea suffer from eutrophication, due to excessive input of nutrients, mostly nitrogen and phosphorus, from surrounding coasts. The transfer of phosphorus is mostly riverine. READ MORE

  3. 2. Methane flux in the Doñana wetlands : Waterbird guano addition and benthicinvertebrate effects

    University essay from

    Author : Noa Ratia; [2019]
    Keywords : aquatic invertebrates; bottom-up effects; CH4; Doñana; greenhouse gases; mesocosm; methane; sediment cores; akvatiska evertebrater; bottom-up effekter; CH4; Doñana; mesokosm; metan; sedimentkärnor; växthusgaser;

    Abstract : Wetlands are globally important biogeochemical hotspots, and their roles as either significant sources of greenhouse gas or carbon sinks are strongly controlled by environmental drivers such as carbon, nitrogen, and phosphorus availability, which can stimulate emission of three greenhouse gases: nitrous oxide (N2O), carbon dioxide (CO2) and methane (CH4). Mounting evidence suggests that aquatic invertebrate activity can enhance wetland greenhouse gas flux, through bioturbation and bioirrigation of surrounding sediments. READ MORE

  4. 3. Phosphorus in the sediment of L. Hällerstadsjön: spatial distribution, fractions and release to the water volume

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : NANA OSAFO; [2016]
    Keywords : Bioavailable phosphorus; Eutrophication; Phosphorus fractionation; Phosphorus flux; Sediments.;

    Abstract : : In freshwater systems phosphorus (P) is the limiting element in the cause of eutrophication. In many Swedish lakes, causes of eutrophication have been attributed to more of internal loading than external since the external loading has been fairly well managed. READ MORE

  5. 4. Where do the nutrients come from? : A case study from the agricultural landscape of Sibou village

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Hanna Wiborgh; [2015]
    Keywords : ;

    Abstract : This study investigates the source of nutrients in an agricultural landscape in Kenya. Kapshoi furrow has its intake from Embobut River and flows through the village of Sibou until it reaches the plots in the lowland in Keu. READ MORE

  6. 5. Parameters affecting dephosphorization of stainless steel

    University essay from KTH/Materialvetenskap

    Author : Erik Wendel; Axel Andersson; [2015]
    Keywords : dephosphorization; stainless steel;

    Abstract : A literary study has been made to find parameters affecting dephosphorization of stainless steel. Ways to lower phosphorus content without major loss of chromium in order to decrease the production costs of Sandvik AB’s stainless steel. READ MORE
