  2. 16. Fate and transport of POPs in the aquatic environment : with focus on contaminated sediments

    Author : Sarah Josefsson; Karin Wiberg; Mats Tysklind; Kjell Leonardsson; Jonas S Gunnarsson; Jussi Kukkonen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioturbation; bioirrigation; bioaccumulation; secondary sources; buried contaminants; sediment remediation; active capping; thin-layer capping; Marenzelleria spp.; Baltic Sea; polychlorinated dibenzo-p-dioxins; polychlorinated dibenzofurans; polychlorinated biphenyls; hexachlorobenzene; octachloro¬styrene; polybrominated diphenyl ethers; PCDD Fs; PCBs; HCB; OCS; PBDEs; water sampling; passive sampling; particulate fraction; freely dissolved; apparently dissolved; colloid; organic carbon; activated carbon; lignin; sediment-to-water flux; spring bloom; Environmental chemistry; Miljökemi; Persistent organic compounds; Persistenta organiska föreningar; Environmental Science; miljövetenskap;

    Abstract : Persistent organic pollutants (POPs) are hydrophobic substances that readily sorb to organic matter in particles and colloids instead of being freely dissolved in the water phase. This sorption affects the bio­availability and environmental transport of the POPs. READ MORE

  4. 17. Occurrence and fate of emerging and legacy flame retardants : from indoor environments to remote areas

    Author : Seth Newton; Cynthia de Wit; Ulla Sellström; Matthew MacLeod; Roland Kallenborn; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Flame retardant; emerging; legacy; polybrominated diphenyl ethers; PBDE; HBCDD; long range transport; dust; air; soil; atmospheric deposition; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Persistent organic pollutants (POPs) are toxic chemicals that can be found in various matrices in all corners of the planet, including remote areas such as the Arctic.  Several POPs are known and monitored but given the abundance of new chemicals in commerce about which little is known, chemicals that may be new POPs are constantly being screened for.

  5. 18. Synthesis of highly brominated diphenyl ethers and aspects on photolysis and indoor spreading

    Author : Anna Christiansson; Åke Bergman; Eva Jakobsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

    Abstract : Adding chemicals to materials to decrease flammability can be dated back to as early as 450 BC when the Egyptians used alum to reduce flammability of wood. Almost 2500 years later brominated flame retardants (BFRs) are used to prevent ignition of textiles, electronics and polymers. READ MORE

  6. 19. Modeling of biomembranes: from computational toxicology to simulations of neurodegenerative diseases

    Author : Inna Ermilova; Alexander Lyubartsev; Marta Pasenkiewicz-Gierula; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biomembranes; lipid bilayers; Alzheimer s disease; Parkinson disease; computational toxicology; passive diffusion; hydroxylated polybrominated diphenyl ethers; omega-3; omega-6; amyloid beta peptide; molecular dynamics simulations; SLipids force field; fysikalisk kemi; Physical Chemistry;

    Abstract : It was known from the middle of the last century that a cell-membrane is a lipid bilayer. Since that time a large number of experimental studies has been done in order to see how a certain molecule can penetrate through a membrane. READ MORE

  7. 20. Polybrominated diphenylethers in the environment - Local and long range transport

    Author : Arnout ter Schure; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Substance Flow Analysis; Spatial Variation; Sources; PCB; PBDE; Latitude; Global Fractionation; Frogs; Deposition; Atmosphere; Baltic Sea; Ekologi; Temperature; Washout ratio; Ecology;

    Abstract : I have studied the sources, long range transport, and rates of flow of polybrominated diphenyl ethers (PBDEs), from the technosphere to the Baltic ecosystems. PBDEs are mainly used in polymers, which are applied in electrical equipment to prevent overheating or flashover and are produced in large quantities. READ MORE
