Dias d'Ávila's air quality reflects its position in the Salvador metropolitan northern industrial corridor in Bahia, with vehicle emissions from the BA-093 and the surrounding Polo Petroquímico de Camaçari's industrial expansion northward contributing elevated industrial PM2.5 and vehicle NOₓ. Atlantic trade winds from the Bahia coast provide background ventilation, while the growing petrochemical industrial development drives increasing emissions throughout the year.
