  1. 1. Analysis of PAHs and their transformations products in contaminated soil and remedial processes

    Författare :Staffan Lundstedt; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; polycyclic aromatic hydrocarbons; PAHs; degredation; transformation; formation; accumulation; oxidation products; metabolites; oxogenated polycyclic aromatic hydrocarbons; oxy-PAHs; soil; gasworks; remediation; bioremediation; bioslurry; wood-rotting fungi; Fenton´s reagent; avaliability; bioavaliability; chemical analysis; extraction; pressurized liquid extraction; PLE; accelerated solvent extraction; ASE; Miljökemi; Environmental chemistry; Miljökemi; analytisk kemi; Analytical Chemistry;

    Sammanfattning : Soil that is heavily contaminated with polycyclic aromatic hydrocarbons (PAHs) is often found at the sites of former gasworks and wood-impregnation plants. Since PAHs are toxic these sites represent a hazard to human health and the environment, and therefore they need to be treated, preferably by a method that destroys the contaminants, and thus eliminates the problem permanently.

  3. 2. Stadens ljus : Etableringen av de första svenska gasverken

    Författare :Arne Kaijser; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Gas technology; 19th century Sweden; Public utilities; Urban technology; Infra-structure; Decision-making process; Technology transfer; History of technology; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The earliest Swedish gasworks, built around 1850 in Gothenburg, Norrköping and Stockholm, were the first public utilities in Sweden. The establishrnent of these gasworks forced the municipal authorities for the first time to make decisions concerning a complicated technical system - decisions which involved not only technical, but also financial, organizational and legal components.

  4. 3. Chemical and bioanalytical characterisation of PAH-contaminated soils : identification, availability and mixture toxicity of AhR agonists

    Författare :Maria Larsson; Magnus Engwall; Jessika Hagberg; Peter Haglund; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polycyclic aromatic compounds; Soil; Risk assessment; Mixture studies; AhR-mediated activity; REPs; GC MS; H4IIE-luc bioassay; Chemistry; Kemi;

    Sammanfattning : Contaminated soils are a worldwide problem. Polycyclic aromatic hydrocarbons (PAHs) are common contaminants in soil at former industrial areas, especially at old gasworks sites, gas stations and former wood impregnation facilities. LÄS MER

  5. 4. Colonisation and PAH degradation by wood-rotting fungi in contaminated soil

    Författare :Erik Andersson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; agricultural hydrology; Soil Science; Bioteknik; Biotechnology; PLFA; PAH metabolites; PAH; degradation; contaminated soil; soil; brown-rot fungi; white-rot fungi; Colonisation; fungal growth; Lantbrukshydrologi; marklära; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : Bioremediation of soils is considered a low-cost alternative to other remediation techniques. Its ability to remove a number of different pollutants has been demonstrated, relying mainly on the activities of indigenous soil bacteria. LÄS MER
