La Spezia's air quality reflects the Gulf of La Spezia's partially enclosed coastal basin between the Ligurian Apennines and the Portofino promontory, with the Italian Navy Arsenal, container port operations, and vehicle traffic on the A15 motorway generating local sources. The Golfo dei Poeti's enclosed geometry can concentrate port and naval base emissions under calm Mediterranean anticyclonic conditions, while the Ligurian sea breezes provide periodic ventilation.
