Abstract
The study of the fine dust particles distribution in the working area of construction processes
Incoming article date: 20.12.2019This article deals with the study of the characteristics of fine dust particles released on the construction site during the production of works using the lognormal distribution in the calculations. Particles of fine dust, less than 10 microns, represent the greatest risk when inhaled, as they can penetrate into the lungs. The study of the granular composition of the dust released in the air of the working area is approximately expressed as a function of the normal distribution curve, when the diameter of the particles is calculated logarithmically. The presented calculations in the article allow us to determine the distribution of dust on the territory of the construction site and identify the boundaries of the sanitary protection zone, when the value of dust at the border of it will correspond to the maximum permissible emissions.
