1. Aerosol characterization in real life and a methodology for human exposure studies in controlled chamber settings
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
2. Human Pheromones : Psychological and Neurological Modulation of a Putative Human Pheromone
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.

3. Exposure to brominated flame retardants in electronics recycling : air and human plasma levels
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
4. Assessment of human exposure to per- and polyfluorinated compounds (PFCs) : exposure through food, drinking water, house dust and indoor air
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
5. Phthalates: A Full Chain Story : Connecting phthalate sources, indoor dust, human intake, and airway symptoms in children
Sammanfattning : Phthalates are widely used in a large number of consumer goods and building materials from which they can leach and contaminate the environment such as indoor dust and air. It is unclear how phthalate sources in our homes and indoor dust contribute to human intake and airway symptoms in children. LÄS MER
