Congonhas's air quality reflects the Minas Gerais iron quadrilateral mining corridor at 858 metres, with the CSN Presidente Vargas iron ore mining and the surrounding Vale and Gerdau operations generating elevated mineral PM10 and heavy metals alongside vehicle traffic on the BR-040. The elevated Espinhaço highland position aids background dispersal, while the iron ore mining industry's pervasive dust represents the most distinctive local air quality influence throughout the year.
