This research analyzed the relationship between urban block typology and the dispersion of NO₂ and PM10 using the ENVI-met model. Six typologies were studied: vertical, perimeter, semi-open, open, and row. Compact typologies and those with central courtyards showed higher pollutant concentrations due to restricted air circulation but can also create wind corridors that improve air quality along major avenues. The study highlighted the influence of the height-to-width ratio and sky view factor on pollutant dispersion. More open environments, characterized by lower height-to-width ratios and greater sky visibility, promote better air circulation and reduce pollution. These findings emphasize the importance of integrating urban morphology into planning to mitigate pollution and improve public health.
