Paris's Opéra and Grands Boulevards district records elevated air quality exposure driven by some of central Paris's heaviest commercial and tourist traffic. The wide Haussmann boulevards aid dispersal compared to narrower side streets, but sustained vehicle density keeps NO₂ and PM10 consistently above residential averages.
