1. 6. Heated air gaps : a possibility to dry out dampness from building constructions

   Författare :Tord af Klintberg; Folke Björk; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water damage; convection; air gap; building; construction; Building engineering; Byggnadsteknik;

   Sammanfattning : The air gap method is a modification of the common way of building indoor walls and floors. The aim of the method is to make a construction, less fragile to water damage, with air gaps where moisture can be removed with a thermally driven air flow, caused by a heating cable. The thesis includes a number of experimental studies of this method. LÄS MER

3. 7. Organophosphates and phthalates in air and dust from indoor environments : Method development and applied measurements

   Författare :Caroline Bergh; Conny Östman; Peter Haglund; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organophosphate esters; phthalate esters; air; dust; sampling; method development; GC MS; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

   Sammanfattning : Organophosphate and phthalate esters are polymer additives that are frequently found in air and dust in indoor environments. This thesis describes the development and application of air sampling and selective mass spectrometric (MS) determination of these two compound groups. LÄS MER

4. 8. 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. 9. 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

7. 10. The indoor environment in schools : Respiratory effects and air quality

   Författare :Greta Smedje; Uppsala universitet; []
   Nyckelord :Medical sciences; Allergy; asthma; cat allergen; cleaning; dust; formaldehyde; furniture; mould; schoolchildren; ventilation; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; arbets- och miljömedicin; Occupational and Environmental Medicine;

   Sammanfattning : The main objective of this work was to investigate relationships between the schoolenvironment and asthma and asthmatic symptoms in schoolchildren. Data on symptoms werecollected through postal questionnaires answered by 1,732 pupils in 39 randomly selectedschools, and were related to data on exposures obtained through hygienic measurements in theschools.
