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

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

   Abstract : 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. READ MORE

4. 2. Isocyanates - assessment of human exposure

   Author : Håkan Tinnerberg; Avdelningen för arbets- och miljömedicin; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution control; Miljöteknik; kontroll av utsläpp; Analytical chemistry; Analytisk kemi; exposure; biomonitoring; occupational; isophorone diisocyanate; hexamethylene diisocyanate; methylenediphenyl diisocyanate; toluene diisocyanate; amines; aminoisocyanates; polyurethane; isocyanates; Liquid chromatography; Environmental technology; mass spectrometry;

   Abstract : Isocyanates are used mainly for manufacturing of polyurethane (PUR) foams, lacquers, elastomers and glues. The production of PUR exceeds 2 million tonnes per year and is increasing. Occupational exposure to isocyanates are associated with respiratory disorders. READ MORE

5. 3. Human Pheromones : Psychological and Neurological Modulation of a Putative Human Pheromone

   Author : Johan N. Lundström; Mats J. Olsson; Noam Sobel; Uppsala universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Pheromones; Odor; Olfaction; Sensitivity; Psychophysiology; Attention; ERP; Mood; Androstadienone; Estratetraenol; Bimodal distribution; Speed of processing; Psykologi; Psychology; Psykologi;

   Abstract : The notion that humans have specialized chemicals used for communication between conspecifics, so-called pheromones, has attracted much attention and discussion. This thesis demonstrates in four separate studies that a human endogenous steroidal compound that is abundant in male sweat, androstadienone, affects women in several ways that differ to that of common odors.

6. 4. Aerosol characterization in real life and a methodology for human exposure studies in controlled chamber settings

   Author : Christina Isaxon; NanoLund: Centre for Nanoscience; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerosol; human exposure study; exposure; emission; ultrafine particles; aerosol generation; aerosol characterization; candle; terpene; welding; CNT; indoor;

   Abstract : Airborne particles are everywhere around us, and have always been. Particles generated by human activities has increased drastically since industrialization, and several epidemiological studies have shown that inhaled particles can cause adverse health effects. READ MORE

7. 5. Human exposure to persistent organic pollutants : Illustrated by four case studies in Europe

   Author : Jana Weiss; Åke Bergman; Janice Huwe; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human exposure; Persistent organic pollutants POPs ; Environmental chemistry; Miljökemi;

   Abstract : An extensive use of chemicals in countless consumer products has resulted in human exposure to several persistent organic pollutants (POPs). Sufficient knowledge about their chemical composition properties and environmental faith is required, to be able to proper risk assess and regulate the substances. READ MORE
