What affects air quality for runners in Paris
Paris experiences strong urban contrasts, with cleaner parkside zones and higher roadside exposure near the périphérique and major radial routes. Nitrogen dioxide commonly spikes during commuter windows, especially under weak wind conditions. Dense building patterns in older districts can further reduce street-level dispersion and keep pollution concentrated for longer than expected.
