São Miguel dos Campos' air quality reflects the Alagoas coastal lowland zone, with vehicle emissions from the BR-101 and surrounding sugarcane processing and irrigated agriculture contributing local sources. Atlantic trade winds from the Alagoas coast provide background maritime ventilation, while the sugarcane belt's processing operations and seasonal burning add organic aerosols and PM2.5 respectively throughout the harvest season and the coastal proximity generally maintains moderate readings.
