Argenteuil's air quality reflects Greater Paris' northwestern inner suburbs, with the A15 motorway and the Seine river industrial corridor generating elevated NOₓ and industrial PM2.5 alongside the dense urban character. The Seine provides limited ventilation, while prevailing westerlies carry Atlantic air through the Paris basin and the surrounding industrial and logistics character keeps readings among the higher values in the greater Paris metropolitan area.
