1. Colloidal Organic Pollutants in Road Runoff: Sources, Emissions and Effective Treatment Technologies
Sammanfattning : Thousands of organic substances circulate in our society and are diffusely emitted through traffic, combustion and leaching from constructions and building materials into the urban environment. The research in this PhD thesis focuses on road runoff as the highest concentrations of pollutants are frequently found in runoff from areas with high traffic intensity. LÄS MER
2. Novel Technique for Analysing Volatile Compounds in Indoor Dust : Application of Gas Chromatography – UV Spectrometry to the Study of Building-Related Illness
Sammanfattning : It is now generally acknowledged that particulate air pollution can cause respiratory symptoms and that indoor dust particles may be associated with mucous membrane irritation and odour annoyance. One reason for this may be that dust particles adsorb large quantities of gases and other volatile compounds. LÄS MER
3. Titan’s ionosphere and dust : – as seen by a space weather station
Sammanfattning : Titan, the largest moon of Saturn, is the only known moon with a fully developed nitrogen-rich atmosphere, its ionosphere is detectable as high as 2200 km above its surface and hosts complex organic chemistry. Titan’s atmosphere and ionosphere has striking similarities to current theories of these regions around Earth 3.5 billion years ago. LÄS MER
4. Indoor air quality and chemical emissions of organic compounds in newly built low-energy preschools
Sammanfattning : In 2010, the European Union (EU) introduced the “Energy performance of Buildings” directive, which stipulates that all new buildings must reduce their energy consumption by constructing low-energy buildings. This could be achieved by constructing airtight and energy efficient envelopes with functional building materials such as age-resistant plastic films, insulation and different sealing products.

5. Organic dust from pig environment induces activation of human T cells
Sammanfattning : Farmers suffer more frequently from inflammatory airway disorders than the population in general and a ongoing airway inflammation has been shown also in symptom-free healthy farmers. Exposure in a swine confinement building causes an intense airway inflammation with recruitment of inflammatory cells, predominately neutrophils, in healthy, previously, non-exposed subjects.
