  1. 1. Trace element leaching from alum shale fines and red ash from Kvarntorp during a large column test

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Helena Rydfjord; [2022]
    Nyckelord :Alum shale; Leachate; Trace elements; Kvarntorp;

    Sammanfattning : Fuel shortage during the Second World War led to oil production in Kvarntorp, Kumla during 1942-1966 by pyrolyzing alum shale rich in pyrite, FeS2, and organic material such as kerogen. This production has led to a lot of waste laying deposited out in the open after the mining closed and has had negative environmental impact in the form of ongoing weathering and leaching of acidic water and leaching of trace elements into its surroundings.

    Sammanfattning : Limestone is one of the main components of cement production. Limestone has been quarried in Skövde, Sweden, since the end of 19th century and Cementa AB has been operating the quarry since 1973. Aside from limestone, there are also Alum shale of Cambrian age, mudstones as well as bentonite layers of Ordovician age present in the quarry. LÄS MER

  4. 3. ENVIRONMENTAL RADIOLOGICAL STUDIES OF KVARNTORPSHÖGEN Dose and Radiological Risk Assessments for Humans and Biota

    Master-uppsats,

    Författare :Felicia Hultqvist; [2021-04-06]
    Nyckelord :Medical physics; NORM; TENORM; Shale ash; Uranium; Polonium; Radiological risk; Humans; Biota;

    Sammanfattning : Background: The pile Kvarntorpshögen and the lakes Surpölen and Norrtorpssjön are the remains of an industry which mined and processed oil shales to extract oil during World War II. The pile mainly consists of shale ash, a waste from the production, while the lakes are nowadays water-filled mining pits. LÄS MER

  5. 4. Inversion of SkyTEM Data Based on Geophysical Logging Results for Groundwater Exploration in Örebro, Sweden
