Project description It is planned to conduct the research in two stages. Within the scope of this project (the first stage), the subject of research will be an aerosol containing solid particles in the range of (0.5 5) mg/m³, which corresponds to the range of the dust concentration in the air of the working zone. At the next stage, the subject of research will be an aerosol medium, containing solid particles in the range of ( ) mg/m³. This range covers the atmospheric levels of dust concentration.
