The atmospheric aerosol is a complex and dynamic mixture of solid and liquid particles suspended in the atmosphere. These particles are of central importance not only for atmospheric chemistry and physics and for climate, but also they have a profound effect on our lives. Aerosol particles vary greatly in size, sources, chemical composition, concentration, and how long they survive in the atmosphere. They can be primarily emitted by different sources, or form in the atmosphere by condensation or chemical reactions.  

In the seminar, we will explore the aerosol particles major physical and chemical characteristics (size distribution, aerodynamic diameter, chemical composition), how they are emitted in the atmosphere and removed, what are the different emission sources (natural and anthropogenic), how they influence our life (climate, air pollution and health). We will learn how to measure the particulate matter, with focus on the forefront sampling technologies.

In the Czech Republic, several air pollution sampling stations are measuring high levels of particulate matter (PM) every year. The European Union limits for PM10 are frequently exceeded, especially in the winter. The Moravian-Silesia region in particular, is considered as a EU air pollution hot spot. An overview on the air pollution levels in the Czech Republic will be provided. Additionally, the most recent research activities of the Laboratory of Air Quality of the IES will be presented.
