Ariquemes' air quality faces severe seasonal challenges as a major Rondônia Amazon frontier city, with dry season burning from surrounding deforestation generating intense PM2.5 episodes between June and October. Vehicle emissions from the BR-364 contribute year-round, while the flat western Amazon basin's calm dry season conditions allow agricultural smoke to accumulate extensively throughout the region.
