The recent US-Israeli bombing campaign in northern Iran has caused catastrophic scenes, with black smoke filling the skies and black rain falling on the capital city of Tehran. The impact of these attacks raises concerns about the threats to civilian health in Iran and potentially in other countries as well.
On the night of 7 and 8 March, strikes targeted Iran’s oil facilities, resulting in fires in four oil storage facilities and an oil transfer center in Tehran and the nearby Alborz province. The fires created a dramatic sight with flames looming over the city at night and black smoke billowing during the day. The aftermath of the attacks saw soot covering the streets and cars, and most alarmingly, thick black raindrops falling on rooftops and streets in Tehran.
The black rain, likely caused by the smoke from the oil facility fires, poses environmental and health risks. When precipitation passes through polluted air, it can carry soot and other particles to the ground as black raindrops. Experts are concerned about the chemical composition of the smoke and its potential impact on human health.
The smoke from the fires is expected to contain a mix of burnt and unburnt particles, including soot, polyaromatic hydrocarbons, sulphur, and nitrogen oxides. These substances can lead to the formation of acid rain and create a toxic environment. The smoke may also carry particles of materials like concrete, glass, and plastics from the buildings hit by the missiles.
Ingesting black rainwater could cause gastrointestinal symptoms, while exposure to nitrogen and sulphur dioxide in the form of acid rain may irritate the eyes and throat. Inhaling smoke particles can have severe health consequences, including cardiovascular disease, lung cancer, and respiratory issues. The bioaccumulation of toxins in the environment could also contaminate food sources, posing long-term health risks.
While larger particles from the fires may fall out of the atmosphere quickly, smaller particles can travel long distances on the wind. Smoke from the fires could potentially reach other parts of Iran and neighboring countries in the Middle East. People in affected areas are advised to minimize exposure by staying indoors, wearing protective gear, and using alternative water sources if necessary.
The impact of such environmental damage transcends borders, highlighting the interconnectedness of global ecosystems. Vigilance and proactive measures are essential to mitigate the health risks posed by the aftermath of the US-Israeli attacks in Iran.
