Learning Outcomes

The course of Basic Principles and Applications of Aerosol Science is a science course in the area of ​​Atmospheric Pollution. The course deals with Aerosol science and technology.

 As aerosol, a fixed suspension of solid or liquid particles is defined in a gaseous medium, usually air. Aerosols are found everywhere in the environment and are very important for public health as their understanding of their dynamics will lead to an understanding of their effect on humans. Suspended particles or aerosols vary in both concentration and physical, chemical and morphological characteristics. The suspended particles are therefore a mixture of different chemical components derived from different sources and can act as conveyors for various chemical elements and compounds as well as for biological pollutants absorbed or adhered on.

Aerosols have significant effects ranging from human health, visibility, materials destruction to the global climate. Also, aerosols have significant applications in nanotechnology as well as the manufacture of drugs for the human respiratory system. The field of aerosol science and technology has advanced significantly over the last 20 years. There is a great deal of interest in subtle particles, not only in terms of effects on human health but also in relation to their industrial applications. Aerosols also play an important role in the global climate system.

The course examines basic principles of aerosol science and technological applications. First, the fundamental aspects of the aerosol are presented as well as introductory aspects of their dynamics. They also analyze the nucleation and agglomeration mechanisms that are very important for understanding the aerosol dynamics in the atmosphere. Basic principles of measurement and optical properties of aerosols are also presented in conjunction with a study of aerosols and their physicochemical characteristics in indoor and atmospheric conditions. It also examines the dynamics of bio-aerosol based on their sources, concentrations in the air, and methods for measuring them in the air as well as radioactive aerosols. Finally, the effects of aerosols on public health and aerosol deposition in the respiratory system as well as human exposure and dose issues are studied.

 Upon successful completion of the course the student will acquire new knowledge and will be able to:

  • Understand the basic concepts of aerosols and their physicochemical characteristics.
  • Create a set of equations to solve a complex problem for exposure and dose of aerosol.
  • Choose and successfully use the appropriate mathematical tools for the complete solution of a complex process problem.
  • Apply in the field of a simple aerosol test device.
  • Evaluate experimental data from a simple aerosol measuring device with weighted and real-time measurements.
