Pinheiro's air quality reflects the Maranhão coastal lowlands, with vehicle emissions from the BR-316 and surrounding babaçu palm, cattle, and agricultural operations contributing local sources. Dry season burning from surrounding Maranhão Cerrado-Caatinga agricultural land contributes seasonal PM2.5 variation, while the flat Maranhão coastal plain generally allows reasonable wind dispersal on most days and Atlantic trade winds provide moderate coastal background ventilation throughout the year.
