The Chahar-Shanbe Suri culture in Iran is a significant and direct factor leading to air pollution in Iran. Unfortunately, few people recognize the role of culture in dealing with environmental problems. Culture plays an important role in many environmental problems. This study investigates why and how “Chahar-Shanbe Suri” culture leads to increase air pollution in Iran. Following the fireworks of Chahar-Shanbe Suri in Tehran, Tehran's air quality index increase by a high slope, and the clean condition with the 49 index at 20 pm was unhealthy for all segments of society with a 177 index at 23 o'clock.
