Pacajus' air quality reflects the Ceará metropolitan eastern coastal corridor adjacent to Fortaleza, with vehicle emissions from the CE-040 and surrounding industrial district and residential growth contributing local sources. Consistent Atlantic northeast trade winds from the Ceará coast provide background maritime ventilation, while the coastal proximity generally maintains moderate readings and the growing Fortaleza metropolitan expansion drives increasing vehicle emissions throughout the year.
