Simões Filho's air quality reflects the Salvador metropolitan northern industrial corridor in Bahia, with the CIA Aratu industrial complex generating elevated industrial PM2.5 and VOCs alongside vehicle traffic on the BR-324. Atlantic trade winds from the Bahia coast provide general background ventilation, while the industrial concentration of the Simões Filho-Camaçari corridor makes this one of northeastern Brazil's more industrially impacted metropolitan municipalities.
