  1. 1. Mercury in a Swedish landscape over 30 years : a thesis on mercury concentrations in different water-cathments in Krycklan and Degerö stormyr

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Ted Pettersson; Isak Haglund; [2023]
    Nyckelord :Atmospheric deposition; concentrations; dissolved organic carbon; mercury; methylmercury; peatlands; water-catchments;

    Sammanfattning : The purpose of this thesis is to examine trends in concentrations of total mercury (TotHg) and methylmer¬cury (MeHg) in water streams around Vindeln, Sweden, located northwest of Umeå. The relation¬ship between dissolved organic carbon (DOC) and TotHg were also examined in this thesis. LÄS MER

  3. 2. Grain Size Analysis of Late Pleistocene Loess Deposits, Jersey

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Joakim Edlund; [2022]
    Nyckelord :Jersey; loess; grain size; ice age; past climate; Jersey; löss; kornstorlek; istid; forntida klimat;

    Sammanfattning : As the world faces the effects of rapid climate change it is essential that we understand how the Earth’s climate has evolved in recent geological history. The island of Jersey harbours loess deposits which hold clues to recent climate change which have not been extensively studied. LÄS MER

  4. 3. PFAS- En sammanfattning av ny forskning, med ett fokus på föroreningskällor, provtagning, analysmetoder och saneringsmetoder

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Sebastian Nilsson; [2022]
    Nyckelord :föroreningskällor; saneringsmetoder; analysmetoder; PFAS; provtagning; Earth and Environmental Sciences;

    Sammanfattning : PFAS (per- and polyfluoroalkyl substances) is a large group of pollutants that, over the last decade have been of great academic concern since it has been found all around the globe. PFAS is ubiquitous in our environment and frequently found in low background concentrations in soil and water; recent research has also found that PFAS occur in biotic samples, such as fish and plants.

  5. 4. Finding the Lady of the Lake : A Geospatial Analysis of Bronze Age Lake Deposition Sites

    Kandidat-uppsats, KTH/Geoinformatik

    Författare :julia Schulte Koskinen; [2022]
    Nyckelord :GIS; landscape archaeology; Bronze Age; lake; deposits; deposition sites; central Sweden; GIS; landskapsarkeologi; bronsålder; sjö; depåfynd; depåer; mellansverige;

    Sammanfattning : During the Bronze Age, bronze items were sacrificed to the gods by leaving them in the landscape. When making these sacrifices, known as deposits, the Bronze Age people followed certain landscape rules. These rules, and other similarities between the sites, can be rediscovered by analyzing the attributes of the sites. LÄS MER

  7. 5. Temporal Dynamics In Microplastics Within An Indoor Environment: Insights From A Novel Tape-Lifting Method

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

    Författare :Matilda Wiklund; [2022]
    Nyckelord :Microplastics; tape-lifting; atmospheric fallout; urban environments; Mikroplast;

    Sammanfattning : Microplastics (MPs) constitute a risk to both human and environmental health. It is vital to identify sources and pathways to take the necessary action and limit the number of MPs in our environments. However, we currently have a limited understanding regarding MPs' variation with time in urban environments in an indoor setting. LÄS MER
