Unaí's air quality reflects the northwestern Minas Gerais Cerrado at 614 metres, with vehicle emissions from the BR-251 and surrounding soybean, corn, and cattle ranching agribusiness contributing local sources. Dry season burning from surrounding Cerrado agricultural land contributes seasonal PM2.5 variation between June and September, while the elevated plateau position aids background dispersal and the open agricultural plain generally provides reasonable wind dispersal.
