Vantaa's air quality is excellent by European standards, sharing Helsinki's clean Baltic Sea and Gulf of Finland airflows alongside the additional consideration of Helsinki-Vantaa Airport's significant aviation emissions contributing elevated NOₓ and ultrafine particles in the immediate airport corridor. The flat southern Finnish coastal plain generally allows reasonable dispersal on most days, while road dust from studded winter tyres and residential wood burning add seasonal PM variations.
