Salo's air quality is excellent by European standards, with Finland's interior lake and boreal forest airflows providing outstanding natural ventilation in this Häme lakeside city. Vehicle traffic on the E18 motorway and surrounding manufacturing operations contribute local sources, while wood-burning stoves during the long cold winters add seasonal PM2.5 and the surrounding Finnish lake and forest landscape generally maintains excellent conditions throughout most of the year.
