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. Emissions of volatile organic compounds from wood
Sammanfattning : The central aim of this thesis is to support the efforts to counteract certain environmental problems caused by emissions of volatile organic compounds. The purpose of this work was (1) to develop a method to establish the amount of emitted substances from dryers, (2) to determine the effect of drying medium temperature and end moisture content of the processed material on emissions of monoterpenes and other hydrocarbons, (3) to examine the emissions of monoterpenes during production of pellets, and (4) to examine the natural emissions from forests with an eye to implications for modelling.

3. Nitrogen-containing products from atmospheric oxidation of volatile organic compounds
Sammanfattning : Atmospheric oxidation of volatile organic compounds (VOC) produces a wide range of oxygenated organic products that lead to formation of secondary organic aerosol (SOA). SOA represents a significant fraction of the tropospheric aerosol that influence climate and human health. LÄS MER
4. Designing Quinone-based Organic Batteries
Sammanfattning : The demand for secondary energy storage is ever increasing, being at the forefront of the transformation to a sustainable society. Conventional batteries, whose electrode materials require mining and high temperature refining, generate substantial carbon dioxide emissions during production. LÄS MER
5. Chemical emissions from building structures : emission sources and their impact on indoor air
Sammanfattning : Chemical compounds in indoor air can adversely affect our comfort and health. However, in most cases there is only a limited amount of information available that can be used to assess their health risk. Instead the precautionary principle is often applied, i.e. LÄS MER
