Sousa's air quality reflects the Paraíba semi-arid Sertão interior in the upper Piranhas-Açu basin, with vehicle emissions from the BR-230 and surrounding cotton, cattle, and irrigated agriculture contributing local sources. Drought conditions and Caatinga burning contribute seasonal PM10 elevation, while the flat semi-arid terrain generally allows reasonable wind dispersal on most days and the inland position reduces the beneficial Atlantic trade wind coastal ventilation throughout the year.
