União dos Palmares' air quality reflects the Alagoas coastal Zona da Mata, with vehicle emissions from the BR-104 and surrounding sugarcane processing and agricultural operations contributing local sources. Atlantic trade winds from the Alagoas coast provide general background maritime ventilation, while the sugarcane belt's harvest season processing operations add organic aerosols and the coastal proximity and consistent Atlantic winds generally maintain moderate readings throughout most of the year.
