Abstract

The author of the article analyzes existing methods for calculation of pollutants’ dispersion in the atmosphere from a short continuous source under constant meteorological conditions. For this purpose the “SKAT” copyright software system elaborated by author was used. Furthermore, the author makes conclusions about advantages of using “Paskvilla method” for the calculation of gaseous substances’ dispersion from sources of this type.

Highlights

  • The ecology of the regions is significantly affected by pollutants from the sources of natural and anthropogenic origin

  • - The pollutant dispersion in the atmosphere is affected by meteorological parameters; - The ground-level concentration of pollutants depends on the parameters of the emission source and composition of the air-gas mixture

  • The OND-86 technique is currently approved at the state level and recommended for use to calculate the emission dispersion in the air while rationing and limiting maximum permissible emissions (MPE)

Summary

Introduction

The ecology of the regions is significantly affected by pollutants from the sources of natural and anthropogenic origin. Pollutant emissions enter various processes of air traffic, are released to the ground, spread in the hydrosphere contaminating the surface and groundwater. Mathematical models and techniques adequately reflecting the dispersion of these substances in the atmosphere are required to describe and predict pollutant transport in the environment
