Boa Vista's air quality faces severe seasonal challenges as the capital of the northern Brazilian state of Roraima, bordering Venezuela and Guyana where dry season savanna and forest burning can generate some of Brazil's most extreme PM2.5 episodes. Vehicle emissions from the growing city contribute year-round, while the flat northern Brazilian savanna's dry season burning events between January and April regularly dominate regional air quality.
