  2. 6. Concentrate or dilute contaminants? : Strategies for Swedish wood waste

    Author : Joakim Krook; Anders Mårtensson; Stefan Anderberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Management strategies; environmental aspects; heavy metals; separation; regulation; market interactions; actors; avfall; miljö; sortering; föroreningar; tungmetaller; impregnerat trä; styrmedel; kundkrav; lagstiftning; Environmental engineering; Miljöteknik;

    Abstract : This thesis aims to assess the environmental consequences of management strategies for wood waste in Sweden. There is a special focus on separation strategies and in what way such measures influence environmental aspects such as the presence of heavy metals in the waste. READ MORE

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

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

    Abstract : 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.

  5. 8. Temporal and spatial trends of organohalogens in guillemot (Uria aalge) from North Western Europe

    Author : Hrönn Jörundsdóttir; Åke Bergman; Derek Muir; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arctic; environmental; monitoring; pollution; time trends; spatial trends; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

    Abstract : The Arctic and sub-Arctic region of the North Atlantic is a remote area, also in relations to environmental contaminants, such as POPs, BFRs and last but not least, PFCs. Both the BFRs and PFCs are considered emerging pollutants of significant environmental concern. READ MORE

  6. 9. Mixture Effects of Environmental Contaminants

    Author : Erik Lampa; Monica Lind; Jonas Björk; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mixtures; Environmental Contaminants; Atherosclerosis; Metabolic Syndrome; Boosting; Epidemiology;

    Abstract : Chemical exposure in humans rarely consists of a single chemical. The everyday exposure is characterized by thousands of chemicals mainly present at low levels. Despite that fact, risk assessment of chemicals is carried out on a chemical-by-chemical basis although there is a consensus that this view is too simplistic. READ MORE

  7. 10. Metal sorption to ferrihydrite : phosphate effects, X-ray absorption spectroscopy and surface complexation modelling

    Author : Charlotta Tiberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Phosphorus affects the sorption of many metals and arsenate to iron (hydr)oxides. This may influence the mobility and bioavailability of metals and arsenate. Phosphorus therefore plays an important role in, e.g. READ MORE
