Thérmi's air quality reflects the eastern Thessaloniki metropolitan suburban corridor near the Macedonian International Airport, with aviation and vehicle emissions generating elevated NOₓ and ultrafine particles alongside vehicle traffic on the surrounding Thessaloniki ring road. The airport's flight corridor makes Thérmi one of Macedonia's more aviation-influenced suburban communities, while the enclosed Thessaloniki basin concentrates all metropolitan emissions under winter temperature inversions throughout the heating season.
