  1. 21. Child labour and health hazards: chemical exposure and occupational injuries in Nicaraguan children working in a waste disposal site

    Författare :Steven Cuadra; Avdelningen för arbets- och miljömedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; child labor; waste disposal sites; health hazards; heavy metals; persistent organochlorine pollutants; brominated flame retardants; occupational injuries; Nicaragua; barnarbete; avfallshanteringsplatser; hälsorisker; tungmetaller; beständiga klororganiska föroreningar; bromerade flamskyddsmedel; yrkesskador; Nicaragua;

    Sammanfattning : About 600 children and teenagers work at Managua's landfill, the largest in Nicaragua. They collect and sort waste at the open dump, which covers an area of 7 km2 on the outskirts of the city on the shores of Lake Managua. LÄS MER

  3. 22. Linking exposure pathways to internal concentrations of brominated flame retardants in Swedish mothers and their toddlers

    Författare :Leena Sahlström; Cynthia A. de Wit; Ulla Sellström; Urs Berger; Jochen Mueller; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; BFR; PBDE; HBCD; EBFR; human exposure; serum; feces; house dust; food; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Brominated flame retardants (BFRs) have been used in a variety of consumer products to enhance their fire safety. This has resulted in exposure of the environment, wildlife and humans causing risks of endocrine disruption. LÄS MER

  4. 23. Synthesis of organobromines as a tool for their characterisation and environmental occurrence assessment

    Författare :Andreas Rydén; Göran Marsh; Vladimir Nikiforov; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polybrominated diphenyl ethers; Brominated diphenyliodoniums salts; PBDEs; OH-PBDEs; MeO-PBDEs; Synthesis; Analysis; Abbreviations; Metabolites; Marine natural products; E-waste; Brominated flameretardants; miljökemi; Environmental Chemistry;

    Sammanfattning : Polybrominated diphenyl ethers (PBDEs) have been intensively used as flame retardants (FRs) and have become ubiquitous environmental pollutants. PBDEs form hydroxylated PBDEs (OH-PBDEs) as metabolites. Further, some OH-PBDEs and methoxy-PBDEs (MeO-PBDEs) are natural products. LÄS MER

  5. 24. Determination of some polybrominated flame retardants in biota, sediment and sewage sludge

    Författare :Ulla Sellström; Janneche Utne Skaare; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental Chemistry; miljökemi;

    Sammanfattning : Brominated flame retardants (BFRs) are mainly used in different polymers, and can be released to the environment during industrial processes, during the entire life-time of the flame-retarded product and after disposal. The aim of the present study was to gain knowledge about occurrence and concentrations of some BFRs in the environment, to search for sources for these chemicals and to investigate changes in concentrations over time.

  7. 25. Brominated natural products at different trophic levels in the Baltic Sea : Identification of polybrominated dioxins, hydroxylated and methoxylated diphenyl ethers

    Författare :Anna Malmvärn; Lillemor Asplund; Åke Bergman; Bert van Bavel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polybrominated dibenzo-p-dioxins; hydroxylated polybrominated diphenyl ethers; methoxylated polybrominated diphenyl ethers; Baltic Sea; algae; natural production; Environmental chemistry; Miljökemi; Environmental Chemistry; miljökemi;

    Sammanfattning : Over time, the Baltic Sea has been contaminated by increasing discharges of pollutants from human activities. Persistent organic pollutants (POPs) have caused toxic effects in wildlife and excess of nutrients have led to eutrophication. LÄS MER
