Modeling of Atmospheric Pollution Factors and Public Health Risks in Assessing the Environmental Status of Mining Regions

An assessment of the environmental status of residential areas adjacent to the boundaries of a sulfide-containing waste dump was performed based on integrated modeling of atmospheric pollution factors and public health risks. The near-surface atmospheric layer above the dump surface, adjacent residential areas, and model animals was investigated. Methods of gas surveying and field modeling were used to determine the chemical composition and migration volumes of sulfur compounds, mathematical modeling of their dispersion, and experimental modeling of indicator pathology. Mathematical models of the spatial distribution of sulfur compounds in air flows were constructed; three-component mixtures subject to control were identified; the type of their combined effect and hazard indices were determined; risk pathologies were established. It is concluded that the obtained information can be used to predict morbidity levels of the population under changes in ambient air quality in risk areas.
