1. Analysis of tracer molecules from organic aerosols - Application of liquid phase microextraction to aerosol analysis
Abstract : Airborne particulate matter is well known because of its adverse impacts on human health and its role in climate processes. In order to understand completely the role of aerosols in atmosphere, their chemical composition is of basic importance. READ MORE

2. Development and Evaluation of Methods in Source Apportionment of the Carbonaceous Aerosol
Abstract : Carbonaceous aerosols are known to affect human health negatively and to affect the climate of Earth. As specific types of aerosols originate from specific sources, it is important to know the amount of aerosols emitted from each source. Aerosol source apportionment is an important tool in mitigating air pollution and improving air quality. READ MORE

3. Nitrogen-containing products from atmospheric oxidation of volatile organic compounds
Abstract : 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. READ MORE

4. Characteristics of fresh and aged carbonaceous aerosol from anthropogenic combustion sources
Abstract : Emissions from anthropogenic combustion sources, such as light duty vehicles and small scale biomass combustion, contribute significantly to ambient aerosol particle concentrations both on local and global scales. These emissions have controlling impacts on public health and global climate. READ MORE

5. Formation, ageing and thermal properties of secondary organic aerosol
Abstract : In order to properly represent and predict the effects of aerosol in climate systems, an accurate description of their formation and properties is needed. This thesis describes work done to increase the knowledge of processes and properties of atmospherically relevant secondary organic aerosol (SOA) from both biogenic and anthropogenic origin. READ MORE
