Naples' air quality faces challenges from the dense Campanian coastal basin topography, with Vesuvius to the east and the Camaldoli hills to the north limiting dispersal of vehicle and industrial emissions on calm days. High traffic density, scooter emissions, and the Bagnoli industrial legacy site contribute sustained local pollution, while summer Tyrrhenian sea breezes provide afternoon ventilation relief.
