Ercolano's air quality reflects the Gulf of Naples coastal corridor between Vesuvius and the Tyrrhenian Sea, with vehicle traffic on the A3 motorway and the dense urban residential character generating elevated NOₓ. The Bay of Naples sea breezes provide maritime ventilation, while Vesuvius's fumarolic SO₂ emissions contribute a distinctive volcanic background source and the extremely dense Campanian coastal urban fabric maintains consistently elevated traffic and residential emission readings throughout the year.
