  1. 1. Remediation of materials with mixed contaminants : treatability, technology and final disposal

    Författare :Kristin Elgh-Dalgren; Patrick van Hees; Bert Allard; Dan Berggren Kleja; Örebro universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Bioremediation; Microtox®; mixed contaminants; re-cycling; soil remediation; soil washing.; Environmental chemistry; Miljökemi; Enviromental Science; Miljövetenskap;

    Sammanfattning : Contaminated soils are a large issue worldwide and much effort has been made to find efficient remediation methods. At many contaminated sites, mixtures of dif­ferent contaminants with different properties are present, which may lead to addi­tional problems, and thus additional costs, during the remediation process.

  2. 2. Fungal degradation patterns and toxicity of furfurylated wood

    Författare :Annica Pilgård; Chalmers University of Technology; []
    Nyckelord :Daphtox; Quantitative real-time PCR; Furfurylation; Microtox; Basidiomycota; Acetylation; Wood modification.; Daphnia magna; Thermal modification; Trametes versicolor; Decay; Vibrio fischeri;

    Sammanfattning : The demand for timber products is increasing with global population and affluence. Concerns regarding conventionally used toxic wood preservatives and the deforestation of tropical forests have become more prominent both socially and politically. Wood based products are generally recognised as an environmentally favourable raw material. LÄS MER

  3. 3. Metal Speciation and Toxicity in Urban River Sediments

    Författare :Chen Wei; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; river sediments; sample analysis; metals;

    Sammanfattning : Metal transport, speciation and toxicity were studied in urban runoff and receiving urban river systems. Sediments were recognised as an important environmental compartment for metals. LÄS MER

  4. 4. Semipermeable membrane devices in monitoring of organic pollutants in the aquatic environment

    Författare :Darius Sabaliunas; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; effect studies; environmental monitoring; organic pollutants; bioconcentration; passive samplers; Semipermeable membrane devices; SPMDs; toxicity; genotoxicity; bioassays; Ecology; Ekologi;

    Sammanfattning : Semipermeable membrane devices (SPMDs) are passive samplers capable of concentrating hydrophobic chemicals from water, sediments, soil and air. They consist of layflat polymeric membrane such as polyethylene containing a thin film of synthetic lipid such as triolein. LÄS MER

  5. 5. Metal Speciation and Toxicity in Sewage Sludge

    Författare :Annika Ekvall; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; partition coefficient; toxicity; speciation; sewage sludge; fractionation; metals;

    Sammanfattning : Increasingly stringent controls on metal concentrations in sewage sludge destined for agricultural application provided a basis for the study of the relevance of metal speciation in sewage sludge. A comprehensive literature review identified difficulties in relating metal speciation through single chemical extractions to plant uptake and soil toxicity. LÄS MER
