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

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

    Sammanfattning : 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. LÄS MER

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

    Författare :Seth Newton; Cynthia de Wit; Ulla Sellström; Matthew MacLeod; Roland Kallenborn; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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.

  4. 13. Brominated flame retardants and perfluoroalkyl acids in Swedish indoor microenvironments : Implications for human exposure

    Författare :Justina Björklund; Cynthia de Wit; Thomas Webster; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PBDEs; HBCD; PFOS; PFOA; indoor air; indoor dust; breast milk; human exposure; emission; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Humans are exposed to persistent organic pollutants (POPs) such as brominated flame retardants (BFRs, specifically polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD)) and perfluoroalkyl acids (PFAAs, specifically perfluoroalkane sulfonate (PFOS) and perfluorooctanoic acid (PFOA)). They are used in consumer products found in cars, offices, homes and day care centers. LÄS MER

  5. 14. Levels of brominated flame retardants in humans and their environment : occupational and home exposure

    Författare :Marie Karlsson; Bert van Bavel; Bo Strandberg; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PBDE; BTBPE; DeBDethane; plasma; air; dust; Northern fulmar; egg; household; occupational exposure; Chemistry; Kemi; Kemi; Chemistry;

    Sammanfattning : Plasma from workers at an electronic dismantling plant were analysed for tri- to heptaBDEs (brominated diphenyl ethers), during 18 months. The different exposed groups showed concentrations ranging from 0.06to 2.8 ng g-1 (l. LÄS MER

  7. 15. Toxicity of brominated flame retardants with focus on retinoid system disturbances

    Författare :Sabina Litens Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Brominated flame retardants (BFR) are detected in the environment and biota all over the world. They contribute to the human body burden of industrial chemicals and exposure is mainly via food. Indoor dust contributes substantially in some exposure situations, which involve small children.
