  1. 1. Developmental Neurotoxicity in Mice Neonatally Co-exposed to Environmental Agents PCB, PBDE, Methyl Mercury and Ionized Radiation - Interactions and Effects

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Celia Fischer; Uppsala universitet.; [2008]
    Keywords : Biology; PCB; PBDE; MeHg; ionized radiation; neonatal; development; neurotoxicity; behavior; cholinergic system; Biologi;

    Abstract : This thesis investigates the neurotoxic effects in mice neonatally co-exposed to different toxic environmental agents during a defined critical period of the brains's rapid growth and development.Environmental toxic agents are incorporated in our environment. READ MORE

  2. 2. Human exposure to organohalogen compounds in the Faroe Islands

    University dissertation from Stockholm : Institutionen för miljökemi

    Author : Britta Fängström; Stockholms universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PCB; PBDE; OH-PCB; human serum; NATURAL SCIENCES Chemistry Environmental chemistry; NATURVETENSKAP Kemi Miljökemi;

    Abstract : The Faroe Islands in the North Atlantic are part of the sub-Arctic region, a remote region far from industrial activity. In spite of this remoteness, the Islands are not a sanctuary: exposures and effects of environmental pollutants mar its natural beauty and wildlife. READ MORE

  3. 3. Persistent organic pollutants in the atmosphere - spatial and temporal variations

    University dissertation from Department of Ecology, Lund University

    Author : Cecilia Backe; Lund University.; Lunds universitet.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tropical and temperate regions; global transport; temperature; latitudinal fractionation; fugacity; soil organic matter; soil-air exchange; washout ratio; rain; precipitation; atmosphere; spatial and temporal variations; DDT; PCB; persistent organic pollutants; polychlorinated biphenyls; Environmental chemistry; Miljökemi; Ecology; Ekologi; Chemistry; Kemi;

    Abstract : In these thesis I have studied the spatial and temporal variations of PCBs in the atmosphere and in precipitation in southern Sweden. Further, soil-air exchange processes of PCBs were investigated. Finally, the long-range transport of PCBs and DDT was studied in the Baltic Sea region and in a tropical vs. a temporal region.

  4. 4. Extraction of PCBs from Sediments: Towards Bioavailability Assessment Based on Supercritical Fluid Extraction

    University dissertation from Department of Analytical Chemistry, Lund University

    Author : Tobias Nilsson; Lund University.; Lunds universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; Bioavailability; PCB; SFE;

    Abstract : Persistent organic pollutants (POPs) pose serious threats to our global environment. These compounds have high chemical and biological stability and they are also very lipophilic. READ MORE

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

    University dissertation from Arnout ter Schure, Dept. of Ecology, Chemical Ecology and Ecotoxicology, Sölvegatan 37, 22362, Lund, Sweden

    Author : Arnout ter Schure; Lund University.; Lunds universitet.; [2003]
    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
