Kortrijk's air quality reflects the Leie river valley in the West Flanders industrial and textile corridor near the French border, with vehicle traffic on the E17 and surrounding manufacturing and technology industry contributing local sources. The flat Flemish plain provides reasonable dispersal, while cross-border pollution from the French Lille-Roubaix-Tourcoing textile metropolitan conurbation immediately to the south elevates background PM2.5 and NOₓ above typical Belgian suburban levels.
