Air pollution dispersion is an academic concept and research field that studies the physical and chemical processes by which pollutants introduced into the atmosphere are transported, diluted, and removed. The field investigates the influence of atmospheric conditions, topographical features, and chemical transformations on the spatial and temporal distribution of pollutant concentrations. Its significance lies in enabling the prediction of pollutant levels, assessing their environmental and health impacts, and informing strategies for air quality management and regulatory control.
