Pacatuba's air quality reflects the greater Fortaleza metropolitan area's southern suburban corridor in the Serra de Pacatuba hills, with vehicle emissions from the CE-060 and surrounding mixed residential and industrial character contributing local sources. Consistent Atlantic trade winds from the Ceará coast provide background ventilation, while the Pacatuba highland position at 255 metres provides marginally better dispersal than the flat coastal metropolitan plain and the growing metropolitan expansion drives increasing vehicle emissions.
