Iran's Fight Against Air Pollution: Strategies And Challenges

Iran has been facing air pollution issues, with many of its major cities experiencing smoke, haze, and fumes in the air during certain times of the year. This is due to massive vehicular and factory emissions, construction sites, and the burning of fossil fuels. In 2018, Iran made headlines for a massive dust storm that shut down elementary schools in 15 cities in the Khuzestan province, with people forced to stay indoors and almost 800 hospitalized. Tehran, the capital, is also affected by air pollution, with economic costs of around $2.6 billion annually. To combat this, the Tehran Municipality has shut down businesses and restricted older vehicles, and Iran has adopted higher fuel quality standards, congestion management, and encouraged the use of hybrid and electric vehicles.

The role of industrialization and developing nation status

Iran's industrialization, coupled with its status as a developing nation, plays a significant role in its air pollution challenges. Industrialization, particularly in developing countries, has been a key contributor to environmental degradation, and Iran is no exception.

The process of industrialization has led to increased energy production through the burning of coal and other industrial activities, which contribute to higher levels of air pollution. Iran, as a developing nation, may lack the necessary technology and resources to effectively manage and mitigate the polluting waste generated by these industrial processes. This results in elevated levels of pollutants such as nitrogen dioxide (NO2) and sulfur dioxide (SO2) in the atmosphere, which have detrimental effects on human health and the environment.

Additionally, industrialization has led to a rise in private vehicle ownership and an increase in the number of vehicles on Iran's roads. This increase in vehicular traffic, particularly in major cities like Tehran, contributes significantly to air pollution. The high volume of traffic, including older vehicles with poorer emission standards, leads to higher emissions of nitrogen dioxide and other pollutants. Furthermore, Iran's urbanization has resulted in construction sites, which further contribute to air pollution through the release of particulate matter and other pollutants.

The combination of industrial activities, vehicle emissions, and construction has led to instances of smoke, haze, and fumes blanketing Iranian cities during certain times of the year. This has prompted the implementation of various strategies to combat air pollution, including the adoption of higher fuel quality standards and the encouragement of electric vehicles and bicycles. Tehran, in particular, has taken steps to address air pollution by shutting down polluting businesses and restricting the use of older vehicles.

Moreover, Iran's developing nation status has resulted in challenges in enforcing strict environmental regulations and managing pollution effectively. The lack of resources and infrastructure in urban areas can exacerbate the impact of industrialization on air quality. However, Iran has made some progress in recent years, with the Clean Air Law adopted in 2017 introducing heavier punishments and fines for those who exceed pollution limits.

Vehicular emissions and fuel quality

Iran has been facing air pollution issues, with many of its major cities witnessing smoke, haze, and fumes in the air during certain times of the year. This is primarily due to massive vehicular and factory emissions, as well as construction sites and the burning of fossil fuels. In 2019, Iran's PM2.5 reading was 24.27 μg/m³, which is more than twice the WHO exposure recommendation, ranking it 23rd among all countries.

Vehicular emissions are a significant contributor to air pollution in Iran, particularly in large cities like Tehran. High levels of nitrogen dioxide in the atmosphere indicate a substantial presence of vehicle emissions. The use of older vehicles with archaic technology, such as outdated trucks and buses, has been a persistent issue. To address this, Tehran Municipality has taken steps to restrict the use of these older vehicles and shut down several businesses. Additionally, Iran has been encouraging the production and adoption of vehicles with updated technology, such as hybrid and electric cars, to reduce air pollution.

The country is also facing challenges with fuel quality. Low-quality fuel has been identified as one of the factors contributing to air pollution. Iran has recognized this issue and has implemented higher fuel quality standards in recent years. This includes stricter regulations on the chemical composition of fuels, particularly for ship fuels, which tend to have elevated sulfur content, leading to increased sulfur dioxide emissions.

To further mitigate vehicular emissions, Iran has been promoting the use of bicycles and managing congestion in areas with high vehicle activity. These efforts are supported by the Clean Air Law, adopted in July 2017, which imposes heavier punishments and fines for industries or individuals who exceed pollution limits. As a result of these collective actions, Iran has achieved notable success, reducing black carbon, a major air pollutant, by 50%.

Air pollution control and environmental regulations

Iran has been facing air pollution issues, which have led to a decline in air quality. Many of its major cities experience smoke, haze, and fumes blanketing the air during certain times of the year. This is due to massive vehicular and factory emissions, as well as construction sites and the burning of fossil fuels. In 2019, Iran's PM2.5 reading was 24.27 μg/m³, which is in the 'moderate' pollution bracket according to the WHO. However, in 2020, Iran's PM2.5 concentration increased to 27.2 μg/m3, more than twice the WHO exposure recommendation. Tehran, Iran's capital city, ranked 19th in the world capital city ranking for PM2.5 concentration in 2020.

Air pollution control in Iran is complex and requires strict environmental regulations due to various factors contributing to the issue. One major factor is industrialization, which has led to increased private vehicle ownership, unmaintained vehicles, low-quality fuel, poorly paved roads, and inadequate infrastructure in urban areas. Other sources of pollution include refineries, power plants, industries, household sources, and gas terminals. The burning of fossil fuels, such as coal, and other industrial activities also contribute to air pollution in Iran.

To address these issues, Iran has implemented various measures. The Clean Air Law, adopted in July 2017, introduces heavier punishments and fines for industries or individuals who do not adhere to pollution limits. Tehran Municipality has shut down several businesses and restricted the use of older trucks and buses to combat air pollution. Iran has also adopted higher fuel quality standards and is working to improve traffic management in congested areas. Additionally, the country encourages the use of hybrid and electric vehicles, as well as bicycles, to reduce vehicle emissions.

Despite these efforts, Iran continues to face challenges in reducing air pollution. In 2018, a major dust storm hit the Khuzestan province, leading to the shutdown of elementary schools in 15 cities and causing health issues for residents. Ahvaz, the largest city in southwestern Iran, has particularly high pollution levels due to its industrial activities and proximity to Iraq. The economic costs of air pollution in Tehran are significant, amounting to approximately $2.6 billion annually.

Health and economic costs of air pollution

Iran has been facing air pollution issues that have led to a decline in air quality. This is due to massive vehicular and factory emissions, construction sites, and the burning of fossil fuels. In 2019, Iran's PM2.5 reading was 24.27 μg/m³, which is in the 'moderate' pollution bracket according to the World Health Organization (WHO). However, in 2020, Iran's PM2.5 concentration increased to 27.2 μg/m3, more than twice the WHO's recommended exposure limit.

The health consequences of air pollution are significant. Diseases caused by air pollution cost Iran $260 million, damaging the country's economy by 0.023% of its gross domestic product (GDP). In Tehran, the economic health costs associated with air pollution are about $2.6 billion annually. During a large dust storm in 2018, people in the Khuzestan province were forced to stay indoors, and 806 people were taken to emergency wards, with 39 hospitalized.

The main health risks from air pollution are respiratory and cardiovascular diseases. Fine particulate matter (PM2.5) can penetrate deep into the lungs and enter the bloodstream, causing or exacerbating respiratory and heart conditions. Nitrogen dioxide (NO2) and sulfur dioxide (SO2) are also harmful. NO2 is a major vehicle emission and a helpful indicator of vehicle pollution. SO2 is released from ship fuels and can cause respiratory issues and environmental damage.

Air pollution also has economic costs. In Tehran, for example, the municipality has shut down eight businesses and restricted older trucks and buses to combat air pollution. Iran is also encouraging the production of vehicles with updated technology and the use of hybrid and electric vehicles, as well as bicycles, to reduce pollution from older vehicles.

Overall, air pollution in Iran has resulted in significant health and economic costs, and the country is taking steps to address these issues and improve air quality.
