Ecological Forecasting of Industrial Dust Emissions: Problems and Solutions

Abstract

The results of the study of the levels of atmospheric air pollution by solid particles with different approaches to the accounting of dust and the analysis of the sufficiency and validity of permissible emission standards are presented. On the example of an operating enterprise, taking into account the current inventory, a comparative analysis of the levels of exposure to solid chemicals and the sum of all dusts (TSP) was performed. It is established that the dust factor at the total emission, forms the values of the maximum concentrations 2 times more than the individual chemical components. The presented results confirm the need to review the existing approaches to the regulation of emissions of solid components, including the inclusion in the system of the assessment of the sufficiency of emissions by the criterion of the total impact of dust in general. A correctly estimated level of total dust exposure will allow to exclude an unacceptable level of exposure to solid industrial emissions at the initial stage of the formation of project and environmental documentation (NDV projects).
