  1. 21. Chlorinated organic pollutants in soil and groundwater at chlorophenol-contaminated sawmill sites

    Författare :Ylva Persson; Mats Tysklind; Lars Öberg; Staffan Lundstedt; Jaana Koistinen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; contaminated soil; hydrophobic organic contaminant; chlorinated phenoxyphenol; chlorinated diphenyl ether; chlorinated dibenzofuran; chlorinated dibenzo-p-dioxin; preservation; mobility; colloid; dissolved organic matter; particulate organic matter; groundwater; equilibrium column test; chlorophenol; Environmental chemistry; Miljökemi;

    Sammanfattning : Mixtures of chlorinated organic pollutants can be found in the soils at chlorophenol-contaminated sawmill, including (inter alia) polychlorinated phenols (CPs), phenoxyphenols (PCPPs), diphenyl ethers (PCDEs), dibenzofurans (PCDFs) and dioxins (PCDDs). These hydrophobic compounds have low water solubility and hence low mobility as truly dissolved compounds. LÄS MER

  3. 22. Exploring the ecotoxicity of microparticle debris

    Författare :Zandra Gerdes; Elena Gorokhova; Martin Ogonowski; Tamara Galloway; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microplastics as emerging pollutants; hazard assessment; ecotoxicological experimental design; aquatic toxicology; chemical vector; suspended solids; reference particles; crustaceans as test organisms; behavioural assays in ecotoxicology; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The global distribution and anticipated increase of environmental microplastic (MP) pollution are concerning. However, while the impacts of macroplastic litter on wildlife are apparent, we know relatively little about the MP hazard potential. LÄS MER

  4. 23. Environmental impact of ashes used in a landfill cover construction

    Författare :Igor Travar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Sammanfattning : The landfilling ban for combustible waste in EU countries and the extended use of bio fuels in heat and electricity production will result in an increasing generation of incineration residues, such as fly ash and bottom ash. Instead of landfilling, ashes used as a construction material in, e.g. LÄS MER

  5. 24. Characterisation of residues : Release of contaminants from slags and ashes

    Författare :Ann-Marie Fällman; Rob N.J. Comans; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Residues from industrial processes as well as from energy production utilities have in many cases properties similar to geological materials. They can be used as filling and construction materials if the net environmental impact and the technical properties are acceptable. LÄS MER

  7. 25. Methodology for evaluation of hazards from solid waste and landfill-generated leachate

    Författare :Britt-Marie Svensson; Lennart Mathiasson; Lennart Mårtensson; Ann-Sofi Rehnstam-Holm; Kristianstad University; []
    Nyckelord :;

    Sammanfattning : Avfall har alltid uppkommit i alla samhällen i alla tider. Det vanligaste sättet att hand om det har varit att samla avfallet i soptippar (deponier) på mark som ansetts obrukbar, t.ex. i sankmarker utanför bebyggelsen. LÄS MER
