1. 1. Some Factors Influencing Thermal Comfort and Air Quality in Residential Buildings. Field Measurements and Laboratory Tests

   Författare :Ulf Krüger; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ventilation; air intakes; thermal comfort evaluation; air velocity; indoor air quality; air supply devices; occupation zone; air temperature fluctuations;

   Sammanfattning : The main prerequisite for applying a specific ventilation system in residential buildings is that the demands set upon the indoor air quality and thermal climate can be satisfied. If this cannot be guaranteed using a simple exhaust system, a system with treated supply air, i.e. balanced ventilation, should be considered. 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. 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

5. 4. What contributes to human body burdens of phthalate esters? : An experimental approach

   Författare :Georgios Giovanoulis; Cynthia A. de Wit; Jörgen Magnér; Brice Appenzeller; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Phthalates; Alternative plasticizers; DINCH; In vivo screening; Urine; Nails; Air; Dust; Hand wipes; Duplicate diet; Predictors of exposure; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Phthalate esters (PEs) and alternative plasticizers used as additives in numerous consumer products are continuously released into the environment leading to subsequent human exposure. The ubiquitous presence and potential adverse health effects (e.g. LÄS MER

7. 5. 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
