Bacabal's air quality reflects the Maranhão interior, with vehicle emissions from the BR-316 and surrounding babaçu palm, agricultural, and light manufacturing operations contributing local sources. Dry season burning from surrounding Maranhão Cerrado-Caatinga agricultural land contributes seasonal PM2.5 variation, while the flat Maranhão interior generally allows reasonable wind dispersal on most days throughout the burning season.
