The aim of this work is to analyze the applicability of mathematical models for assessing the degree of atmospheric air pollution, considering the meteorological and geographical conditions of the area. The article systematizes international experience and the accumulated experience of Tajik scientists in monitoring and researching aerosols. A review and comparative analysis of mathematical models have been conducted. Using the city of Khujand as an example, it is shown that to assess the pollution situation, it is necessary to consider the aggregate of industrial, transport, residential, and natural sources, including dust. A phased approach is substantiated as the final methodology, starting with the creation of an emissions inventory and concluding with the validation of mathematical models for subsequent forecasting.
Keywords: atmospheric air pollution, mathematical modeling, air quality, PM2.5, pollution sources, CFD, environmental monitoring.
