Castellammare di Stabia's air quality reflects the Gulf of Naples coastal position between Vesuvius and the Sorrentine Peninsula, with vehicle traffic on the A3 motorway and surrounding industrial and port operations contributing local sources alongside Vesuvius's persistent fumarolic SO₂ background. The Bay of Naples sea breezes provide maritime ventilation, while the volcanic degassing contributes distinctive geogenic emissions and the dense Campanian coastal plain's concentration of traffic and industry maintains elevated readings throughout the year.
