Abstract
Atmospheric aerosol is a complex of solid, liquid or mixed particle size of 1 nm to 100 micron suspended in the atmosphere. A significant component of atmospheric aerosols are also fine particles of minerals from the soil and building materials.
As mineral particles dangerous for human health and with a proven carcinogenic effects are considered fibrous asbestos particles. According the World Health Organization (WHO), as the critical are defined fibers of lenght of 5 microns or longer and in diameter of 3 microns, with a length to diameter ratio of 3: 1 or larger.
Currently, automatic air quality monitoring in city of Pilsen is proceeded by h instruments measured the mass concentration of PM10, PM2.5 and PM1. This method of monitoring only allows a limited analyzes of the size distribution of aerosol mass, or its morphology and chemical composition.
The project aims is to introduce a new method of continuous sampling size separated aerosols with high temporal resolution using 8DRUM or 3DRUM followed by analysis by SEM EDX samples, allowing detailed characteristics of atmospheric aerosols in the atmosphere of Pilsen.
