Igarapé-Miri's air quality reflects the Pará Amazon estuary tidal zone, with consistent Atlantic equatorial airflows providing background ventilation. Vehicle emissions from the PA-154 and the surrounding açaí, timber, and palm heart industry contribute local sources, while dry season Amazon burning from surrounding Pará deforestation generates regional PM2.5 episodes between July and November that represent the primary seasonal air quality challenge throughout the Amazon estuary region.
