Três Corações' air quality reflects the southern Minas Gerais plateau at 848 metres in the historic South de Minas coffee and dairy region, with vehicle emissions from the BR-491 and surrounding coffee, dairy, 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 throughout the year.
