  1. 1. Increasing ecosystem services at an industrial area : A study applied to Rönnskärsverken

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Lisa Larsson; Petra Ljunggren; [2023]
    Keywords : Green areas; Biodiversity; Environmental regulation; Nature Based Solutions; Stormwater management;

    Abstract : What are ecosystem services, what are the possibilities to use them as a solution to remediate environmental problems, and how can they be increased in an industrial area such as Rönnskärsverken? The aim of this master thesis was to investigate the potential and the incentive for increasing ecosystem services in Rönnskärsverken’s industrial area through green areas and nature based stormwater management solutions on the site.  Ecosystem services is a concept that was put on the political agenda in the UN in 2005 in order to create a common definition and valuation to raise awareness of the values that nature provides to human beings.

  3. 2. Markfuktighetsförhållanden och jordartsfördelningens påverkan på kväve- och fosforförluster från skog och sankmark

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

    Author : Eleonor Dacke; [2018]
    Keywords : Övergödning; PLC6 typhalt; typhalt; GIS; flödesackumulering; NNH; TWI; DTW;

    Abstract : Övergödningen utgör ett allvarligt hot mot Östersjön och för att kunna åtgärda problemen krävs effektiva metoder för uppskattning av näringsbelastning och källfördelning. Ökad förståelse för bakomliggande orsaksfaktorer till diffusa näringsförluster från skog och sankmark kan förbättra skattningen av belastning och bidra till riktade åtgärder. READ MORE

  4. 3. Trophic transfer of per- and polyfluoroalkyl substances (PFASs) by glacial relicts in Lake Vättern, Sweden

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Malin Bergman; [2017]
    Keywords : ;

    Abstract : The aim with the study was to assess if glacial relict amphipods constitute as vectors of transport of per- and polyfluoroalkyl substances (PFASs) in the Arctic char food web in Lake Vättern, Sweden. Sediment, surface water and biota samples were analysed for PFASs using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), and stable isotope analysis of δ 13C and δ15N was performed on sediments and biota samples.

  5. 4. Metal Fractionation in Snowmelt Runoff : A Comparison between Ultrafiltration and Diffusive Gradients in Thin Films (DGT) techniques

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Sarah Lindfors; [2017]
    Keywords : Urban Runoff; Metals; Ultrafiltration; Diffusive Gradients in Thin Films;

    Abstract : Urban runoff is a non-point pollution source deteriorating water quality of natural watersystems. The composition of urban runoff vary depending on land use, seasonal changes anddifferent surfaces that come into contact with the water. READ MORE

  6. 5. Mapping leachates and subsurface structures using different geophysical methods.

    University essay from KTH/Mark- och vattenteknik

    Author : David Barkels; Johan Åberg; [2012]
    Keywords : geophysics; tailings; acid mine leachate; pollution mapping; CVES; GPR; slingram;

    Abstract : The enrichment of ore produces large amounts of sulfur and metal-rich residual waste called tailings, which need to be deposited and stored for a long time. When the tailing is oxidized, large amounts of protons and metals are dissolved and diffuse to the groundwater. READ MORE
