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

    University dissertation from Umeå : Kemi

    Author : Ylva Persson; Umeå universitet.; [2007]
    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; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi 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

  2. 2. Dioxins and dioxin-like compounds in thermochemical conversion of biomass formation, distribution and fingerprints

    University dissertation from Umeå : Umeå University

    Author : Qiuju Gao; Umeå universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polychlorinated dibenzo-p-dioxins; polychlorinated dibenzofurans; polychlorinated naphthalenes; PCDD; PCDF; PCN; persistent organic pollutants; torrefaction; pyrolysis;

    Abstract : In the transition to a sustainable energy supply there is an increasing need to use biomass for replacement of fossil fuel. A key challenge is to utilize biomass conversion technologies in an environmentally sound manner. READ MORE

  3. 3. Biological removal of chlorinated organic compounds from kraft bleaching plant effluent

    University dissertation from Department of Biotechnology, Lund University

    Author : Peijie Yu; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermo-alkaline; Aerobic; Anaerobic; Trichloroacetic acid; Kraft bleaching plant effluent; Biological wastewater treatment; Chloroorganic compounds; Biotechnology; Bioteknik;

    Abstract : The microbial decomposition of chlorinated organic compounds in kraft bleaching plant effluent (KBPE) was studied. An aerobic bacterium, Strain TCA1, able to grow on trichloroacetic acid as the sole source of energy and carbon was isolated and characterized. READ MORE

  4. 4. Association of hydrophobic organic compounds to organic material in the soil system

    University dissertation from Umeå : Umeå Universitet

    Author : Silviu-Laurentiu Badea; Umeå universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; HOCs; Organic Matter; Clay; DOM; Environmental Science; miljövetenskap;

    Abstract : Contaminated soils and sediments have been identified as significant secondary sources of organic contaminants.  Leaching tests may be useful tools to estimate the mobility of contaminants via the water phase and thereby the risk for groundwater and surface water contamination.

  5. 5. Characterisation of chlorinated fatty acid metabolites in human cells after uptake of dichlorostearic acid, as determined by a halogenspecific detector (XSD)

    University dissertation from Umeå : Umeå Universitet

    Author : Gunilla Åkesson-Nilsson; Sveriges lantbruksuniversitet.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Chlorinated fatty acids (CIFAs) have been found to account for a considerable portion of the extractable organically bo und chlorine in aquatic animals. Methods particularly suitable for the determination of CIFAs have relatively newly been developed, which may explain why these compounds did not come to attention as a potentially hazardous environmental pollutant until during the recent decade.
