Ílion's air quality reflects the western Athens metropolitan basin in Attica, with vehicle traffic on the surrounding Athenian ring road and the dense urban industrial and residential character generating elevated NOₓ alongside concentrated metropolitan traffic. The enclosed Attica basin concentrates all emissions under persistent temperature inversions, making Ílion one of the Athens metropolitan area's more persistently polluted western suburban environments.
