Improvement of the scheme of neutralization of dust emissions into the atmosphere

Abstract

Emissions of industrial enterprises in their structure are mostly aerodisperse systems, in which the dispersed phase is organic and inorganic dust or fine droplets, and the dispersion phase is a gas-air mixture. This mixture may comprise several contaminating gaseous components. In many cases, the components of the exhaust gases have an additive effect or are capable of transforming into more dangerous compounds, which in the conditions of background concentrations characteristic of most industrialized areas makes them dangerous even at relatively low concentrations in emissions. This problem is exacerbated by changes in industrial infrastructure, the convergence of industrial and residential areas, as well as the emergence of new toxic substances with an insufficiently studied effect. At present, dust is becoming one of the priority pollutants that must be considered when organizing monitoring of the surrounding air. Atmospheric monitoring of dust pollution of the air, being a complex modern task, allows us to determine the actual data on air quality, dust concentration, and trends in its change, and assess the degree of damage caused to human health. We conducted a detailed analysis of the literary data and proposed an influence scheme of fine dust on the environment and ways to improve the neutralization scheme of pollutants on the biosphere, in particular the atmosphere.
