Observational study measures PM2.5 from a restaurant, showing community engagement can drive regulatory change.

PM2.5 levels were significantly higher near the restaurant during cooking, indicating local emission sources impact air quality.
Measurements showed mean PM2.5 of 36.9 µg/m3 within 50 m of the restaurant compared to 13.0 µg/m3 beyond that distance.
Regulatory review revealed only seven states regulate food cookers, underscoring the need for stricter air pollution rules.
Community engagement led to the restaurant changing its cooking fuel, which resulted in reduced smoke and normal PM2.5 levels.
