Numerical models of the distribution of chemically hazardous substances in the air during their emission at industrial enterprises are considered. Scenarios of unorganized emissions at industrial sites or inside industrial premises and organized emissions from low-level sources at an industrial site are modeled. It is known that the consequence of unorganized emissions of toxic substances is air pollution in working areas at industrial sites, atmospheric air pollution in residential areas, and contamination of the underlying surface. With organized emissions at industrial sites, areas with an increased concentration of hazardous substances can also be formed. Very often such situations arise at enterprises when there are organized emissions from low-level sources (emissions on the roof of industrial buildings) and under adverse weather conditions - calm, inversion. 2D and 3D CFD models based on the numerical integration of the fundamental equations of continuum mechanics are proposed.
