In a troubling development, air strikes targeting oil facilities around Tehran have led to a significant spike in pollution, resulting in what experts describe as “unprecedented” environmental degradation. Satellite imagery reveals that smoke from these sites has enveloped the city, prompting warnings from the World Health Organization (WHO) about the potential health risks posed to residents. Since the commencement of US-Israeli military actions on February 28, strikes have been confirmed at multiple oil installations, raising alarms about the immediate and long-term impacts on air quality.
Pollution Plumes and Immediate Health Risks
Recent satellite images indicate that two major oil facilities in Tehran were ablaze as of March 9, following air strikes reported over the weekend. The Shahran depot in the north-west and the Tehran oil refinery in the south-east have been particularly affected, with video footage capturing the intense fireballs that lit up the night sky after the attacks. Reports from local residents describe a thick layer of smog that has obscured sunlight and filled the air with the acrid scent of burning materials.
Air quality has become a pressing concern, as the ongoing fires release a cocktail of hazardous chemicals into the atmosphere. The complex nature of the pollutants—comprising carbon monoxide, soot, sulphur, and nitrogen oxides—suggests that residents are facing significant health risks. The WHO has highlighted that such attacks on oil infrastructure could severely contaminate essential resources such as food and water, exacerbating health issues, especially among vulnerable populations like children and the elderly.
The Phenomenon of ‘Black Rain’
On Sunday, residents reported experiencing “black rain,” a term used to describe rainfall tainted with pollutants. This occurrence is not typical; it signifies high levels of soot and other contaminants in the air. According to Dr Akshay Deoras from the University of Reading, raindrops can act as collectors, trapping airborne pollutants as they descend. While it is standard for rain to wash out some pollutants, the phenomenon of black rain is rare and indicates a severe environmental crisis.
The presence of black rain suggests that the fallout from the air strikes is not merely an immediate concern but poses ongoing risks. As these pollutants settle, they can enter waterways or be resuspended into the air by wind, prolonging the exposure of Tehran’s population to harmful substances.
Expert Opinions on the Environmental Impact
Leading researchers are alarmed by the scale of the pollution generated by the strikes. Dr Eloise Marais, an expert in atmospheric chemistry at University College London, stated that the level of pollutants released through these air strikes is typically only seen in the aftermath of catastrophic industrial accidents. This unique situation, characterised by a wide range of harmful chemicals being discharged into a densely populated urban environment, has raised significant environmental and health concerns.
Doug Weir, director of the Conflict and Environment Observatory, emphasised the rarity of such attacks occurring in such a populated area, which heightens the risks of exposure. Unlike rural oil fields, facilities in urban centres like Tehran pose immediate dangers to a large number of people.
Rain Forecasts and Ongoing Risks
Despite forecasts of rain predicted for the coming days, which could help disperse some of the airborne pollutants, experts caution that the threats posed by these contaminants will not simply dissipate. Pollutants could infiltrate local water systems or become airborne again as the ground dries, maintaining the risk to public health.
The WHO’s Director-General, Dr Tedros Adhanom Ghebreyesus, has voiced serious concerns regarding the health implications of the ongoing conflict. He stressed that the intense particulate exposure is likely to have immediate effects on respiratory health and could lead to long-term complications, including increased cancer risks.
Why it Matters
The situation in Tehran serves as a stark reminder of the interplay between military conflict and environmental health. The unprecedented levels of pollution resulting from targeted air strikes on oil facilities not only compromise air quality but also threaten the health and well-being of millions of residents. As these conflicts unfold, the ramifications extend beyond immediate military objectives, laying bare the critical need for comprehensive strategies to safeguard public health in war-torn regions. The unfolding crisis highlights the urgent requirement for international attention and action to mitigate the impacts of such environmental disasters on civilian populations.
