Strikes on four oil storage depots near Tehran created massive fires producing toxic black smoke over a city of 9 million. Black, oil-tainted rainfall has been reported. The environmental damage may persist for years, similar to Kuwait's 1991 oil field fires.
Yes. Residents have reported oil-tainted black rainfall as toxic smoke from burning oil depots mixes with atmospheric moisture. This is similar to what occurred during the 1991 Kuwait oil fires.
Kuwait's oil fires caused respiratory issues, soil contamination, and groundwater pollution lasting 15+ years. Tehran's proximity to a major population center makes the health impact potentially worse.
