  1. 6. Nanoplastic transport in soils by advection and bioturbation

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Wiebke Mareile Heinze; [2019]
    Nyckelord :column leaching; attachment efficiency; exposure; mixing rates; modelling;

    Sammanfattning : Micro- and nanoplastics are increasingly perceived as an emerging threat to ecosystems. They are emitted to soils through different pathways, including sewage sludge or compost applications in agriculture, or through tire abrasion and degradation of mismanaged waste. LÄS MER

  3. 7. Hydrus-1D as a tool to understand contamination of an aquifer: A case study in the Central Valley of Cochabamba

    Kandidat-uppsats, Lunds universitet/Teknisk geologi

    Författare :Theo Nyberg; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In water resource management, it is of importance to be able to predict how different activities might contaminate aquifers. For this kind of application, numerical modelling of water and solute transport can be a useful tool. LÄS MER

  4. 8. Simulation of Leachate Generation from a Waste Rock Dump in Kiruna Using HYDRUS-1D

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Aryani Atmosudirdjo; [2019]
    Nyckelord :Hydrus-1D; matrix flow; leachate; unsaturated flow; waste rock dump;

    Sammanfattning : The percolation of water through waste rock dumps at mine sites can lead to the production of a leachate with high concentrations of dissolved metals, sulfate and nitrogen compounds. It is important to understand how water flows in waste rock dumps in order to predict the environmental impact of this leachate on recipients. LÄS MER

  5. 9. Effects of Organic Matter on Virus Removal with New and Used Sand in Tunåsen Infiltration Basin, Uppsala, Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Stacy Sutliff-Johansson; [2015]
    Nyckelord :MS2; time-dependent removal; adsorption; organic matter effects; virus contamination; Uppsala; MS2; adsorption; organiskt material effekt; virus kontaminering; dricksvatten; Uppsala;

    Sammanfattning : Artificial infiltration has been increasing in popularity in Sweden as a way to combat over-abstraction of groundwater aquifers from growing municipalities. However, enteric virus contamination of drinking water sources is a concern as infiltrating surficial waters are easily contaminated from human activities. LÄS MER
