Penedo's air quality reflects the Alagoas lower São Francisco river valley, with vehicle emissions from the AL-101 and surrounding sugarcane, cattle, and agricultural operations contributing local sources in this historic colonial city. Atlantic trade winds from the Alagoas coast provide background maritime ventilation, while the sugarcane belt's processing operations add organic aerosols during the harvest season and the coastal proximity generally maintains moderate readings throughout most of the year.
