Rijeka's air quality reflects its position in the Kvarner Gulf, with the Bakar industrial zone's oil refinery and petrochemical operations generating elevated SO₂ and industrial PM2.5 alongside vehicle traffic on the A6 motorway and the busy Adriatic ferry port. The surrounding Gorski Kotar and Učka massifs create topographic variation, while the Bura wind provides powerful periodic ventilation from the Dinaric Alps throughout the year.
