11. Utforskade dataanalys av bäckarna i Undersviks Tillväxtpark före BAG-försök
Kandidat-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Förorening av vatten är ett stort problem både på lokal och global nivå. Övergödning från mänsklig aktivitet såsom jordbruk och industrier utgör ett markant hot mot våra vatten (Rheinheimer 1998), å andra sidan skulle skogsbruket kunna förbättra sin produktion med större nyttjande av gödsel.

12. Ammonium and nitrate sorption by biochar
Master-uppsats, SLU/Dept. of Soil and EnvironmentSammanfattning : Biochar has recently drawn attention due to its ability to increase soil fertility, sequester carbon and its expected effect on reducing the leaching of elements from the soil, especially nitrogen. The possibility of using biochar as a soil amendment to reduce the amount of nitrogen leaching, and then reducing the quantities of nitrogen fertilizers used in agriculture to avoid the bad environmental effects has become a matter of great interest.

13. In-Situ Gold Resource Estimation Using Satellite Remote Sensing and Machine Learning in Defunct Tailing Storage Facilities (South Africa)
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The mining industry generates billions of tonnes of waste annually, which is often stored in tailings storage facilities (TSF). This waste is generated from the extraction of ore from surface or underground mines, as well as from metallurgical processing and low-grade stockpiles. LÄS MER
14. Spatialanalys av markgeokemi : Hur utlakningshalter av markgeokemin varierar i Sveriges morän enligt interpolationsmetoder
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : The purpose of this study was to evaluate the spatial distribution of geochemistry in Swedish till and whether interpolations could predict unknown values of geochemistry between samples at a national spatial level, Sweden, and a regional, the county of Västerbotten. The information of the spatial distribution of the elements and the interpolations accurateness has several applications. LÄS MER
15. Investigation of unknown groundwater flows to two leachate ponds at Hovgården
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The leaching of groundwater into two polishing ponds, the last step in the wastewater treatment process on Hovgarden waste facility, was examined. The focus of this study was to analyse the PFAS composition profile (fingerprint) to trace the leaching groundwater. LÄS MER
