Korydallós' air quality reflects the Piraeus western metropolitan corridor, with vehicle traffic on the surrounding Athenian port approach roads and the dense urban industrial and residential character generating elevated NOₓ and port-related PM2.5. The Attica basin's enclosed topography concentrates all metropolitan and maritime emissions under persistent temperature inversions, while Korydallós' port-adjacent industrial position and the Piraeus shipping corridor amplify maritime emission exposure throughout the year.
