  1. 1. Investigating the Fluxes of Radio-Cesium (137Cs) in Sweden : Investigating the Fluxes of Radio-Cesium (137Cs) in Sweden

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Hammad Masood; [2022]
    Nyckelord :Chernobyl incident; Sweden; radio-cesium; contamination; terrestrial environment; quatic environment;

    Sammanfattning : Technological advancement and the quest for power have gradually contaminated our environment, as industrialization, agriculture, and nuclear activities progressed. In the year 1986, a terrible nuclear incident occurred in Ukraine, in which the nuclear reactor exploded. LÄS MER

  3. 2. Stabilisering och solidifiering av muddermassor : En studie av det praktiska utförandet

    M1-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakulteten

    Författare :Albin Holmgren; Daniel Karlsson Fagerberg; [2022]
    Nyckelord :Stabilisering; solidifiering; förorenade muddermassor; sediment; S S; Köping; hamn;

    Sammanfattning : Enligt en inventering som gjorts av 40 svenska hamnar kommer minst 2,5 miljoner kubikmeter förorenat sediment behöva tas omhand de närmaste åren (Holm, 2011). Stabilisering och solidifiering är idag det mest aktuella alternativet till deponering på land och dumpning till havs, alternativ som enligt avfallslagen i största möjliga mån bör undvikas. LÄS MER

  4. 3. Environmental radiation measurements at Barsebäck nuclear power plant during the decommissioning phase

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Patrik Dahlström; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background and aim: The Barsebäck nuclear power plant (NPP) units ceased operations in 1999 and 2005. Now the NPP is in the phase of decommissioning, which is a complicated process that will take many years to complete. Radiological characterization of the surrounding area is a part of the decommissioning process. LÄS MER

  5. 4. Biochar-based thin-layer capping of contaminated sediment in Burefjärden, northern Sweden : Assessment of biochar mixed into four structural materials for preventing release of trace elements from sediment to water

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Nathalie Pantzare; [2021]
    Nyckelord :biochar; contaminated sediment; remediation; thin-layer capping;

    Sammanfattning : Coastal areas around the world have been recognized as largely impacted by anthropogenic activities resulting in pollution of marine sediments. In Sweden, surveys conducted along the coastline of the Bothnian Bay have identified a total area of about 29 km2 as fiber rich sediments. LÄS MER

  7. 5. Methods for measuring mercury in gas ebullition from fiber banks : A literature study

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Diana Jonsson; [2021]
    Nyckelord :Fiber bank; fiber rich-sediment; mercury; contaminants; gas ebullition; pulp-fiber; wood industry; paper industry; environmental toxicity; wood waste;

    Sammanfattning : Mercury contamination is an environmental issue with high priority due to its high toxicity. In addition to the atmospheric deposition, several lakes and rivers in Sweden are contaminated as a result from wood and pulp-fiber industries which stretches back 200 years. LÄS MER
