Chignahuapan's air quality reflects the Puebla Sierra Norte's Apulco River valley at 2,800 metres, with vehicle traffic on surrounding roads and the traditional handicrafts, Christmas ornament manufacturing, and agricultural corridor contributing distinctive craft emissions alongside primary vehicle sources. The elevated highland position aids dispersal, while the Christmas ornament industry's distinctive glass and lacquer operations represent Chignahuapan's most locally unique air quality contribution throughout most of the year.
