  2. 1. Halogenated organic matter in precipitation

    Author : Krzysztof Laniewski; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Deposition in rain and snow plays a crucial role in the regional and global redistribution of a great variety of substances. This thesis is devoted to chemical characterisation and identification of the halogenated organic compounds that are most widespread in rain and snow. READ MORE

  4. 2. Theoretical Photochemistry : Halogenated Arenes, Phytochromobilin, Ru(II)polypyridyl complexes and 6-4 photoadducts

    Author : Anders Borg; Sten Lunell; Hans Karlsson; Luis Serrano-Andrés; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; Quantum Chemistry; Halogenated Arenes; Phytochromobilin; Phytochrome; Ruthenium; 6-4 photoadducts; Photochemistry; Kvantkemi; Quantum chemistry; Kvantkemi;

    Abstract : This thesis presents Quantum Chemical calculations on the Photochemistry of Halogenated benzenes, Phytochromobilin, Ruthenium Polypyridyl complexes and 6-4 photoadducts in DNA. The work is focused on improving the understanding of a number of experimentally observed photochemical processes in these systems. READ MORE

  5. 3. What contributes to human body burdens of halogenated flame retardants? : An experimental approach

    Author : Joo Hui Tay; Cynthia de Wit; Ulla Sellström; Jochen Mueller; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; halogenated flame retardants; air; dust; hand wipes; duplicate diet; serum; human exposure; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Flame retardants (FRs) are chemicals added to a broad range of consumer products such as textiles, electrical and electronic equipment, furniture and building material to meet flammability requirements. Most of these chemicals are additives that can continuously leach out from the applied products during usage. READ MORE

  6. 4. Persistent halogenated pollutants in mothers´ milk

    Author : Johan Fång; Åke Bergman; Cathrine Thomsen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; miljökemi; Environmental Chemistry;

    Abstract : Persistent organic pollutants (POPs) are substances that degrade slowly, are distributed wotldwide, bioaccumulate and are harmful to both animals and humans. The release of POPs to the environment was the preamble to human background contamination. READ MORE

  7. 5. Halogenated structures in natural organic matter

    Author : Carina Johansson; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Chloroorganics have long been assumed to be almost exclusively of anthropogenic origin, and this assumption has played an important role in the public debate regarding the use of chloriue and emissions of chlorine-containing organic compounds. However, studies undertaken during the past decade have demonstrated that, in general, the total amounts of organically bound chloriue in soil and water by far exceed the possible anthropogenic input.
