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