Montreuil's air quality reflects its position in Greater Paris' densely urbanised eastern inner suburbs, with the A3 and surrounding ring road network generating sustained NO₂ alongside the dense residential and commercial character. Prevailing westerlies carry the central Paris metropolitan pollution plume eastward through Montreuil, while the flat Seine plain's limited dispersal barriers keep readings consistently elevated throughout the year.
