Franca's air quality reflects its position on the São Paulo state northeastern plateau at 1,029 metres, with vehicle emissions from the BR-146 and the leather footwear and manufacturing industry that defines this major shoe production centre contributing elevated PM2.5 and VOCs. The elevated plateau position aids background dispersal, while dry season burning from surrounding São Paulo state agricultural land contributes seasonal variation and the leather tanning operations add localised chemical emissions.
