  1. 1. Factors Controlling Mercury Concentration in Rivers in the Mackenzie River Basin, Northwestern Canada

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Jack Hewitt; [2020]
    Nyckelord :mercury; Mackenzie River Basin; regression; Canada; community-based water monitoring;

    Sammanfattning : Mercury (Hg) in rivers and streams of the Mackenzie River Basin (MRB) presents a risk to fish, aquatic mammals, and humans. This thesis makes use of newly-released water quality data, including total mercury (THg) and dissolved mercury (DHg), gathered through the NWT-Wide Community-based Water Quality Monitoring (CBM) program.

  3. 2. Monitoring dissolved organic carbon in Swedish forest streams after wildfire

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :William Mcneice; [2016]
    Nyckelord :forest fire; sensor; organic matter; monitoring;

    Sammanfattning : In situ water quality monitoring devices (sondes) allow monitoring of dissolved organic matter (DOC) continuously at a high resolution via measurements of fluorescent dissolved organic matter (fDOM). Two sondes were used to test the hypothesis that DOC in local streams would decrease in concentration immediately after forest fire. LÄS MER

  4. 3. Effekter av kalavverkning på mindre boreala sjöars vattenkvalitet

    Kandidat-uppsats, Institutionen för ekologi, miljö och geovetenskap

    Författare :Linda Lundgren; [2014]
    Nyckelord :Forestry; clear-cut; lakes; DOC; TN;

    Sammanfattning : Forestry is an important industry in Sweden, with clear-cut as the most commonly used method for harvesting. Here the long-term impact of clear-cut on lake water quality (dissolved organic carbon (DOC), nitrogen, phosphorus and pH) has been investigated, based on 23 lakes sampled during autumn. LÄS MER

  5. 4. Mineraliska material som reaktiva filter för avskiljning av tungmetaller från dagvatten

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för geovetenskaper

    Författare :Anna Lindquist; [2005]
    Nyckelord :Reactive filters; adsorption; mechanisms for removal; urban storm water; heavy metals; column studies; batch experiments; blast-furnace slag; iron oxide; olivine; nepheline.;

    Sammanfattning : Highly polluted urban storm water from e.g. highways can contain large amounts of heavy metals that may cause harm if they are discharged into recipients. LÄS MER

  7. 5. Snow cover dynamics and plant phenology documentation using digital camera images and their relation with CO2-fluxes at Stordalen mire, northern Sweden

    Magister-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Susanne Svensson; [2005]
    Nyckelord :naturgeografi; climatology; cartography; carbon flux; climate monitoring; physical geography; snowmelt; pedology; geomorphology; geomorfologi; marklära; kartografi; klimatologi; Earth and Environmental Sciences;

    Sammanfattning : This report investigates the utilization of digital camera images (DCIs), sensitive in the visible part of the spectrum, for documentation of seasonal and inter-annual variations in snow cover and plant phenology. The DCIs used were transformed to orthographic images (ortho-image) from ordinary oblique DCIs taken between January 2001 and December 2003 at a sub- arctic mire (Stordalen) in northern Sweden.
