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

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

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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.

5. 4. Exposure to brominated flame retardants in electronics recycling : air and human plasma levels

   Författare :Anneli Julander; Magnus Engwall; Bert van Bavel; Myrto Petreas; Örebro universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PBDE; BTBPE; DeBDethane; Thyroid hormone; Occupational exposure; Human plasma; Air sampling; MeO-PBDE; PBDE; BTBPE; DeBDetan; Sköldkörtelhormon; Yrkesexponering; Human plasma; Luftprovtagning; MeO-PBDE; Environmental engineering; Miljöteknik; Enviromental Science; Miljövetenskap;

   Sammanfattning : Polybrominated diphenyl ethers (PBDEs), 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE) and 1,2-bis(2,3,4,5,6-pentabromophenyl)ethane (DeBDethane) were analysed in air and blood samples from workers at an electronics recycling facility. The samples were collected regularly for 18 months and were analysed by isomer specific GC/MS analysis in both electron impact (EI) and negative chemical ionisation (NCI) mode. LÄS MER

7. 5. Assessment of human exposure to per- and polyfluorinated compounds (PFCs) : exposure through food, drinking water, house dust and indoor air

   Författare :Ingrid Ericson Jogsten; Gunilla Lindström; Bert van Bavel; Stuart Harrad; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; human exposure; per- and polyfluorinated compunds PFCs ; dietary intake; drinking water; indoor environment; TECHNOLOGY; TEKNIKVETENSKAP; Environmental chemistry; Miljökemi; Chemistry; Kemi; Miljökemi; Environmental Chemistry; Kemi; Chemistry;

   Sammanfattning : Per- and polyfluorinated compounds (PFCs) are detected in humans worldwide but all sources of human exposure have not been fully characterized. The aim of this thesis was to evaluate the contributions from food, water, air and dust as sources for human PFC exposure in the general population. LÄS MER
