Piraçununga's air quality reflects the São Paulo state interior plateau at 634 metres, with vehicle emissions from the SP-330 Anhanguera and the Pirassununga air force base military aviation operations contributing elevated NOₓ and aviation PM2.5 alongside the primary local sources. Dry season burning from surrounding sugarcane agricultural land contributes seasonal PM2.5 variation, while the elevated plateau position aids background dispersal throughout the year.
