    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

  3. 7. Indoor and Outdoor Air Pollution in Relation to Allergy and Asthma in Taiyuan, China

    Författare :Zhuohui Zhao; Dan Norbäck; Jan Sundell; Uppsala universitet; []
    Nyckelord :Medical sciences; Indoor air; China; School; Allergen; Dust; Microbial exposure; SO2; Air pollutants; Epidemiology; MEDICIN OCH VÅRD;

    Sammanfattning : The aim was to study the prevalence of asthma, eczema, allergy and respiratory symptoms among pupils in Shanxi province, China, in relation to home and school environment and outdoor air pollution. In one study there was a low prevalence of self-reported asthma, eczema and pollen or pet allergy among pupils (9-20y). LÄS MER

  4. 8. Moisture Buffering in the Indoor Environment

    Författare :Kaisa Svennberg; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; furniture; textiles; moisture buffering; beds; indoor air; indoor environment; sorption isotherms; field measurements; definition scheme; Technological sciences;

    Sammanfattning : Moisture buffering in the indoor environment is the ability, through absorption and desorption, of surface materials to attenuate the moisture variations of the indoor air. Moisture buffering plays an important role in understanding the risks for biological growth in surface materials in the indoor environment, e.g. LÄS MER

  5. 9. 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.

  7. 10. Indoor air quality and chemical emissions of organic compounds in newly built low-energy preschools

    Författare :Josefin Persson; Thanh Wang; Jessika Hagberg; Pim Leonards; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Indoor air quality; volatile organic compounds; brominated flame retardants; organophosphate flame retardants; low-energy preschools; environmental certification; indoor dust; surface wipes;

    Sammanfattning : In 2010, the European Union (EU) introduced the “Energy performance of Buildings” directive, which stipulates that all new buildings must reduce their energy consumption by constructing low-energy buildings. This could be achieved by constructing airtight and energy efficient envelopes with functional building materials such as age-resistant plastic films, insulation and different sealing products.
