  2. 1. Colonisation and PAH degradation by wood-rotting fungi in contaminated soil

    Author : Erik Andersson; Bioteknik; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Automation, hyphenation and multidimensional chromatography for PAH analysis : Analytical techniques to simplify sample complexity

    Author : Hwanmi Lim; Roger Westerholm; Christoffer Bergvall; Stephen Wise; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; polycyclic aromatic hydrocarbon; PAH; benzo[a]pyrene; B[a]P; carcinogenicity; cancer risk assessment; complex matrix; automation; hyphenation; multidimensional chromatography; two-dimensional; method translation; online fractionation; benz[j]aceanthrylene; B[j]A; relative potency factor; Analytical Chemistry; analytisk kemi;

    Abstract : One group of organic environmental pollutants which are potentially hazardous to human health is polycyclic aromatic hydrocarbons (PAHs). These compounds consist of two or more benzene rings in their structure among which benzo[a]pyrene (B[a]P) is classified as a human carcinogen. READ MORE

  5. 3. Spatial variability linking carbon resource heterogeneity and microorganisms; causes and consequences

    Author : Niklas Törneman; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bakteriologi; virologi; mykologi; Environmental chemistry; Miljökemi; Mikrobiologi; mycology; virology; bacteriology; Microbiology; Ekologi; Ecology; Geostatistics; Microbial activity; Soil organic carbon; Microbial diversity; Biodegradation; Bioremediation; PAH; Spatial patterns;

    Abstract : Organic carbon and bacteria have a high variability at different scales in the soil, and organic carbon may be a limiting factor for growth of soil bacteria. Thus, it can be expected that these co-vary at different scales in the soil. READ MORE

  6. 4. Emissions from Fires Consequences for Human Safety and the Environment

    Author : Per Blomqvist; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kontroll av utsläpp; pollution control; Miljöteknik; Environmental technology; Byggnadsteknik; Building construction; incapacitation; CFD; simulations; emissions; particles; dioxin; PAH; gases; quantitative analysis; fire effluents; chemical characterisation; large-scale experiments;

    Abstract : Accidental fires represent a risk for people from the heat and fire effluents produced. It is clear from fire statistics that it is, in fact, the toxic gases that kill and injure many fire victims. Further, there are a number of compounds that are readily produced in fires, which have important sublethal effects on humans. READ MORE

  7. 5. Protein unfolding by interfaces and interactions between polycyclic aromatic hydrocarbons

    Author : Svetla Chakarova Käck; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; first-principles calculations; PAH; denaturation; protein-interface interactions; van der Waals interactions; lattice models; polycyclic aromatic hydrocarbons; DFT; density functional theory;

    Abstract : In order to theoretically study large and complex systems, a variety of approaches that can be categorized loosely as top-down or bottom-up are followed. While our vision is to bridge the gap between these approaches and use them together in multiscale materials modeling, the present thesis is limited to give examples of each type of approach in the study of soft-matter systems.
