  1. 1. 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

  3. 2. Estimating children’s exposure to per- and polyfluoroalkyl substances

    Författare :Kerstin Winkens; Ian T. Cousins; Urs Berger; Robin Vestergren; Heather M. Stapleton; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PFAS; PFAA; fluorinated; fluorotelomer; FTOH; PAP; early life; child; human; exposure; intake; indoor; bedroom; air; dust; serum; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFASs) are highly stable, surface active chemicals, which are water- and oil/stain-repellent. Because of their unique properties, PFASs are widely used in consumer products. LÄS MER

  4. 3. Nanomaterials : respiratory and immunological effects following inhalation of engineered nanoparticles

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nanoparticles; nanomaterials; inhalation; lung; metalloxides; immunologi; Immunology; Toxicology; toxikologi; lungmedicin; Lung Medicine; Occupational and Environmental Medicine; arbets- och miljömedicin; nanopartiklar; nanoparticles; nanotoxikologi; nanotoxicology;

    Sammanfattning : Background Nanotechnology is an important and promising field that can lead to improved environment and human health and contribute to a better social and economic development. Materials in nanoscale have unique physiochemical properties which allow for completely new technical applications. LÄS MER

  5. 4. Engineered nanomaterials in in vivo and in vitro models

    Författare :Laura Abariute; NanoLund: Centre for Nanoscience; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V semiconductor nanowires; Nanoparticle exposure; Mouse exposure; Cell exposure; Nanotoxicology; Nanosafety; Fysicumarkivet A:2018:Abariute;

    Sammanfattning : Nanotechnology and engineered nanomaterials (ENM) empower existing technologies. One of the great examples are III-V semiconductor nanowires (NW), which have a broad application range. The occupational safety and hazard organizations draw attention to ENM, as their physical and chemical characteristics differ from the ones of bulk materials. LÄS MER

  7. 5. Development and comparison of in vitro toxicity methods for nanoparticles : Focus on lung cell exposure

    Författare :Siiri Latvala; Karine Elihn; Hanna Karlsson; Lennart Möller; Hannu Norppa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Concerns for the toxic effects of airborne nanoparticles have been raised along with the increasing production of nanostructured materials. However, the health risks of nanoparticle exposure are currently not fully understood. The most commonly used techniques to study nanoparticle toxicity, both in vivo and in vitro, have several limitations. LÄS MER
