Turku's air quality is generally good by European standards, benefiting from the Baltic Sea and the Archipelago Sea providing consistent maritime ventilation across Finland's oldest city. The Port of Turku's ferry operations to Stockholm and Tallinn contribute shipping NOₓ along the harbour corridor, while vehicle traffic on the E18 and wood-burning stoves during cold winters are the primary local sources throughout the year.
