  1. 11. 3D-printing of undisturbed soil imaged by X-ray

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

    Författare :Matthias Bacher; [2013]
    Nyckelord :soil; macropores; 3D-printing; X-ray;

    Sammanfattning : An artificial soil pore network can help to analyse preferential macropore flow which is important for pollutant leaching and degradation in the environment. Reproducing soil macro pores in an artificial, durable material offers the opportunity of repeating experiments in contrast to real soil pore networks. LÄS MER

  3. 12. Kemisk stabilisering av gruvavfall från Ljusnarsbergsfältet med mesakalk och avloppsslam : Chemical stabilization of mine waste with sewage sludge and calcium carbonate residues

    Kandidat-uppsats, Institutionen för geovetenskaper

    Författare :Linda Höckert; [2007]
    Nyckelord :gruvavfall; sulfidmalm; pyrit; oxidation; kolonntest; skaktest; utlakning; stabilisering; mesakalk; efterbehandling;

    Sammanfattning : Chemical stabilization of mine waste from Ljusnarsbergsfältet with sewage sludge and calcium carbonate residues Mine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. LÄS MER

  5. 14. En jämförande studie mellan uppmätt och MACRO-simulerad pesticidutlakning på ett odlingsfält i Skåne

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Malin Sundler; [2001]
    Nyckelord :geografi; geologi; MACRO-simulering; pesticidutlakning; Skåne; Earth and Environmental Sciences;

    Sammanfattning : The Swedish Environmental Protection Agency (Naturvårdsverket) manages an environmental supervisor program in which they attempt to calculate the amount of pesticide leaching in various catchments in different parts of Sweden. In the present study, this kind of calculation was done for the Vemmenhög catchment in southern Sweden using the MACRO simulation model. LÄS MER
