Research on the extent of environmental pollution by foundry emissions

Abstract

The results of the study of emissions of harmful substances from sources of foundries with different production patterns are given, the share of foundry shops in emissions is determined, calculations of dispersion of harmful substances in the atmosphere are made, and air pollution is estimated in nearby residential areas and enterprise territories.The assessment of the share of foundries in environmental pollution by machine-building enterprises showed that they make up about 82% of dust, about 60% of carbon oxide, about 70% of nitrogen dioxide, about 93% of phenol, formaldehyde, etc.
