  1. 16. Application of 2D fluorescence spectroscopy on faecal pigments in water : characterization of wastewater fluorescence and potential indication of faecal pollution

    University essay from SLU/Dept. of Energy and Technology

    Author : Bärbel Daub; [2017]
    Keywords : wastewater; faecal pollution; faecal pigment; fluorescence; urobilin; stercobilin;

    Abstract : Drinking water pollution by faeces and associated enteric pathogens can cause serious health issues and outbreaks of diseases. A fast and reliable indication of faecal pollution is necessary to prevent the consumption of polluted water. READ MORE

  3. 17. PFAS in recipient sediment of a military airport

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Lovisa Johansson Blomér; [2017]
    Keywords : Per- and polyfluoroalkyl substances; PFAS; PFOS; Sediment; Military airport; Per- och polyfluorerade alkylsubstanser; PFAS; PFOS; sediment; militär flygplats;

    Abstract : Per- and polyfluoroalkyl substances, PFASs, are highly fluorinated substances where the carbon chain is fully- or partly fluorinated. A functional group is coupled at the end of the carbon chain which gives PFASs their different properties. READ MORE

    University essay from Lunds universitet/Matematisk statistik

    Author : Axel Sundberg; Olle Bristedt; [2017]
    Keywords : Mathematics and Statistics;

    Abstract : Abstract—This article have been written in cooperation with The Swedish Defense Research Agency (FOI). The article proposes a method to calibrate hydrophone positions for improved underwater survailence in The Baltic Sea. READ MORE

  5. 19. Geochemistry of stream plants and its statistical relations to soil- and bedrock geology, slope directions and till geochemistry : a GIS-analysis of small catchments in northern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Harry Eriksson; [2017]
    Keywords : Biogeochemistry; GIS; Physical Geography and Ecosystem analysis; Geographical Information Systems; Geochemistry; Catchments; Drainage areas; Earth and Environmental Sciences;

    Abstract : Subaquatic mosses and stream plants have been recognized as suitable sample media for detection of geochemical variations in their surrounding environments. These plants were originally used in search for mineral deposits but later on also for detection of environmental pollution. READ MORE

  6. 20. Hydrological modeling enhancement using GIS : An improved topographic wetness index for wetland detection

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Patricia Rull; [2016]
    Keywords : Blue spots; digital dams; culverts; hydrologically enforced DEM; topographic wetness index; TWI; soil-topographic wetness index; STI; wetland detection;

    Abstract : Hydrological modeling, like runoff modelling for flood prevention, is based on digital elevation models (DEMs). The fact that the DEMs do not represent existing road culverts can lead to considerable hydrological misinterpretations. READ MORE
