Alagoinhas's air quality reflects its position in the Bahia interior Agreste region, with vehicle emissions from the BR-101 and the surrounding agricultural and petroleum extraction operations contributing local sources in this oil industry service hub. The elevated Bahia Agreste plateau position generally aids background dispersal, while dry season burning from surrounding Bahia agricultural land contributes seasonal PM2.5 variation, and the Petrobras oil field extraction operations in the surrounding Remanso-Alagoinhas petroleum area add localised industrial emissions.
