Santa Isabel do Pará's air quality reflects its position in the greater Belém metropolitan area in the Pará Amazon estuary, with vehicle emissions from the BR-316 and surrounding mixed agricultural and urban growth contributing local sources. Atlantic equatorial airflows provide background ventilation, while dry season Amazon burning from surrounding Pará deforestation generates intense PM2.5 episodes between July and November that dominate the metropolitan air quality seasonally.
