What affects air quality for runners in New York
New York air quality varies significantly between dense traffic corridors, waterfront zones, and neighborhood streets with lighter flow. Nitrogen dioxide often peaks near highways, bridges, and major bus routes, while PM2.5 reflects both local emissions and regional background transport. Building density can intensify street-level exposure in some parts of Manhattan and the Bronx.
