Lappeenranta's air quality is generally good by European standards, benefiting from the Finnish Lake Saimaa system's clean boreal lake district airflows providing natural ventilation in this southeastern Finnish city near the Russian border. Vehicle traffic on the E18 motorway and the surrounding paper and chemicals manufacturing industry contribute local sources, while wood-burning stoves add seasonal winter PM2.5 throughout the year.
