Dunkerque's air quality faces significant industrial challenges as France's largest port and steel city, with ArcelorMittal's coastal steelworks and surrounding petrochemical operations generating elevated SO₂ and PM2.5 alongside the busy English Channel shipping lane. North Sea westerlies generally provide strong maritime ventilation, but the industrial complex's scale makes Dunkerque one of northern France's more persistently challenged urban industrial environments throughout the year.
