What affects air quality for runners in Bangkok
Bangkok's air quality is strongly influenced by dense traffic, urban development, and meteorology that can limit dispersion. Major roads and freight routes are persistent hotspots for nitrogen dioxide and fine particles. In tightly built districts, low wind speeds can allow pollutants to accumulate and produce noticeable day-to-day exposure differences.
