Recent U.S.-Israeli Bombardments of Iranian Oil Depots Pose Serious Short‑ and Long‑Term Risks for the Population and Ecosystems, Says WHO and Environmental Protection Groups

Sunday, 8 March 2026 – The sky over Tehran, Iran’s capital, was darkened. Fine particles released by the explosions at oil depots turned raindrops black.

“Black Rain” and “Acid Rain” Threaten Tehran Residents

Christian Lindmeier, spokesperson for the World Health Organization (WHO), warned that the “black rain” and “acid rain” falling on Tehran since the strikes “represent a danger” for Iranians.

He added that the WHO is in contact with hospitals and authorities. The United Nations agency is also monitoring health risks linked to the massive release of toxic hydrocarbons, sulfur oxides, and nitrogen compounds into the atmosphere.

Long‑Term Health and Environmental Impacts

The WHO spokesperson emphasized that these pollutants can have long‑term effects, especially on respiratory health, while also contaminating water sources.

  • Plants suffer too: Acid rain destroys minerals and essential nutrients needed for tree growth.
  • Although not an immediate threat to people directly exposed to the precipitation, acid rain enters the water cycle and can travel to regions far from its point of origin.

Growing Concern Over War‑Induced Environmental Damage

While environmental damage is secondary to the human casualties of armed conflict, it is receiving increasing attention because of its indirect consequences on public health.

Researchers from Kuwait have reported that pollutants released by oil‑well fires during the 1991 Gulf War tripled the number of cancer cases in Kuwait and raised the incidence of neurological diseases, asthma, and allergies.
