  2. 22. Chlorinated organic pollutants in soil and groundwater at chlorophenol-contaminated sawmill sites

    Author : Ylva Persson; Mats Tysklind; Lars Öberg; Staffan Lundstedt; Jaana Koistinen; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 23. Medieval Timber Roof Structures: Conceptual methods for investigation and evaluation of structural behaviour, with the horizontal thrust problem as an application
