ABOUT NEW APPROACHES IN THE ESTIMATION OF THE IMPACT OF DUST ON THE RESPIRATORY SYSTEM
Features of the aerodynamics of aerosols in the respiratory tract during respiration are considered. New methodological approaches to the evaluation of the intensity of the exposure to dust on the human respiratory organs are proposed. The difference in the dispersion composition and in the weight concentrations of the inhaled dust from the dust of the working zone air was studied. The dispersed composition and weight concentrations of cotton dust retained by separate parts of the respiratory organs were investigated. The selective ability of separate parts of respiratory organs to detain dust particles of various sizes has been detected. The regularity of the distribution of dust particles of different disperse composition and weight concentrations over separate parts of the respiratory organs is established.
