Queluz's air quality reflects the northern Sintra-Cascais metropolitan corridor west of Lisbon, with vehicle traffic on the IC19 and A9 CREL motorways and the surrounding dense suburban residential character contributing elevated NOₓ and PM2.5. The Tagus estuary's Atlantic ventilation is partially blocked by the Sintra ridge, while Queluz's motorway corridor proximity and dense urban character keep readings consistently among the higher values in the greater Lisbon metropolitan area.
