"Atmospheric dispersion and transmission play an important role in the behavior and effects of air pollution. Human health can be adversely affected by air pollution in a variety of ways, both immediately and over time. The Hybrid Single Particle Lagrangian Integrated Trajectory Model (HYSPLIT) modeling program, a computer model and software package, tracks the transport trajectories and distributions of air pollution and various pollutants, including radioactive pollutants, in the atmosphere. It also facilitates research on pollution sources. This study simulated the transport of hazardous aerosols in St. Louis region for the years 2020, 2021, and 2022 using the HYSPLIT modeling program. First, the monthly and seasonal atmospheric transport of St. Louis region was determined using the HYSPLIT program in 2020, 2021, and 2022. It also analyzed the air pollutants observed in St. Louis region in 2020, 2021, and 2022. Then, the dates when hazardous aerosols would be at their highest were determined. Backward and forward trajectories were calculated using the HYSPLIT modeling program, and cluster analyses were performed on pollutants entering the region and pollutants being transported out of the region. As a result of the research, the use of fireworks during Fourth of July celebrations has been linked to an increase in the concentration of PM2.5 and SO2 in the atmosphere"-- Abstract, p. iii
