Rueil-Malmaison's air quality reflects Greater Paris' western inner suburb adjacent to La Défense, with vehicle traffic on the A86 and the surrounding corporate headquarters and residential corridor contributing elevated NOₓ. The Seine river provides limited ventilation, while prevailing westerlies carry Atlantic air through the Paris basin and the La Défense proximity keeps readings above central Paris residential averages for much of the year.
