Néa Smýrni's air quality reflects the southern Athens metropolitan basin, with vehicle traffic on the surrounding Athenian ring roads and the dense urban residential character generating elevated NOₓ under the enclosed Attica basin's persistent temperature inversions. The Hymettus mountain ridge to the east provides topographic backdrop, while the Attica basin's characteristic enclosed geometry concentrates all metropolitan emissions across this southern Athens suburb throughout the year.
