Maisons-Alfort's air quality reflects Greater Paris' southeastern inner suburb on the Marne-Seine confluence, with vehicle traffic on the A4 and surrounding mixed residential and veterinary research character generating elevated NOₓ. The Marne-Seine confluence provides limited ventilation, while prevailing westerlies carry the broader Paris metropolitan pollution eastward and the dense urban industrial-residential character maintains consistent moderate to elevated readings in this major inner Paris commuter suburb throughout the year.
