Petrolina's air quality reflects its position in the São Francisco River valley in the Pernambuco-Bahia semi-arid border region, with vehicle emissions from the BR-407 and the surrounding irrigated fruit farming and wine production corridor contributing local sources. Drought conditions and dry season burning from the Caatinga landscape contribute elevated PM10, while the São Francisco valley's channelling of northerly and southerly winds provides generally reasonable ventilation across this major semi-arid agricultural and energy hub.
