Several large cities in Iran, especially Tehran, recently observed peak air pollution. That has exceeded the acceptable concentration of air pollutants, especially particulate matter, black carbon, sulfur dioxide, and ozone levels. The primary origins of air pollutants in Tehran include human activities, such as road transportation, oil refineries, industrial bases, and mines, as well as natural origins, such as local and regional dust events, which can expose citizens to high levels of air pollutants. Although guidelines are in position and massive actions are being taken to manage air pollution issues in Iran, performance and enforcement could be more practical. The significant challenges are the inefficiency of policies and management approaches, the requirement for more air quality monitoring techniques and technology, especially in industrial cities rather than Tehran, and the demand for examinations on the efficiency of principles. Screening such information can carry possibilities for global cooperation, which is essential in addressing air pollution worldwide. It is critical to be aware of the hazards of air pollution and report them to people to minimize their exposure threats by supplying air purifiers, clean spaces, and masks.
