Crateús's air quality reflects the Ceará semi-arid Sertão interior in the Ibiapaba foothills, with vehicle emissions from the BR-020 and surrounding cattle, cotton, and agricultural operations contributing local sources. Drought conditions and Caatinga burning contribute seasonal PM10 and PM2.5 elevation, while the Ibiapaba highlands to the west create topographic variation and the semi-arid climate creates naturally dusty conditions during dry windy periods throughout the year.
