  2. 11. In situ remediation of contaminated sediments using thin-layer capping : effectiveness in contaminant retention and ecological implications

    Author : Göran Samuelsson; Jonas Gunnarsson; Maria Granberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thin layer capping; sediment remediation; activated carbon; contaminated sediment; benthic community; Systems Ecology; systemekologi;

    Abstract : Hydrophobic organic contaminants (HOCs) often reside in sediment sorbed to particles, most tightly to particles with high content of organic carbon. If persistent, such pollutants can accumulate in the sediment for many years and constitute a contamination risk for sediment-living organisms and organisms at higher trophic levels, including humans.

  4. 12. Remediation of mercury polluted soil

    Author : Thomas Lifvergren; Bert Allard; Örebro universitet; []
    Keywords : soil pollution; soil remediaion; mercury; NATURAL SCIENCES; NATURVETENSKAP; Enviromental Science; Miljövetenskap;

    Abstract : Mercury in contaminated soil constitutes a wide spectrum of species with highly different properties due to the chemical complexity of the element. Assessments of risk, ecological effects and removal potential require process and mobility studies. READ MORE

  5. 13. Soil Remediation and Sustainable Development : Creating Appropriate Solutions for Marginalized Regions

    Author : Henrik Haller; Anders Jonsson; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The scope of this doctoral thesis is appropriate soil remediation methods for marginalized regions that go beyond pollution reduction targets and include strategies to support sustainable development. Contaminated soil from industrial or agricultural activities poses potential health threats to animals and humans and also threatens economic systems by making land unsuitable for agriculture and other economic purposes.

  6. 14. Application of two dimensional compound specific carbon-chlorine isotope analyses for degradation monitoring and assessment of organic pollutants in contaminated soil and groundwater

    Author : Charline Wiegert; Örjan Gustafsson; Thomas Hofstetter; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organochlorines; chlorinated ethenes; PCE; TCE; hexachlorocyclohexanes; soil contamination; groundwater contamination; remediation; natural attenuation; biodegradation; carbon isotopes; chlorine isotopes; CSIA; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Nearly 250,000 sites with past and present potentially polluting activities need urgent remediation within Europe. Major pollutants include organochlorines (OCls), e.g. chlorinated ethenes (CEs) and hexachlorocyclohexanes (HCHs), mainly used as industrial solvents and pesticides, respectively. READ MORE

  7. 15. Source, mobility and fate of critical Be, Bi, F and W from historical sulfidic-oxidic skarn tailings : Re-mining as remediation method?

    Author : Lina Hällström; Lena Alakangas; Olof Martinsson; Heather Jamieson; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad geokemi; Applied Geochemistry;

    Abstract : There is a potential risk that geochemical cycles of several critical metals will be affected in the pristine environment, when mining of these metals increases to meet the demand in green technology. The identification of critical metals is based on the economic importance and vulnerability to supply restrictions. READ MORE
