Alfenas' air quality reflects the southern Minas Gerais plateau at 833 metres in the South de Minas coffee region, with vehicle emissions from the MG-179 and surrounding coffee, eucalyptus, and agribusiness operations contributing local sources. The elevated plateau position aids background dispersal, while dry season burning from surrounding Minas Gerais agricultural land contributes seasonal PM2.5 variation and the coffee processing operations add distinctive organic aerosol emissions during the harvest season.
