Santana's air quality in Brazil reflects the Amapá state capital's position on the Amazon estuary near Macapá, with vehicle emissions from the local road network and surrounding port and industrial operations contributing local sources. Atlantic equatorial airflows provide general background ventilation, while dry season burning from surrounding Amapá and Pará Amazon deforestation generates regional PM2.5 episodes between July and November that represent the primary seasonal challenge.
