Massive oil fires in Tehran have released a cocktail of toxic chemicals into the atmosphere, posing a significant health risk to millions of people. The impending black rain is expected to exacerbate this issue, as it will likely pull carcinogenic particles, soot, and petroleum residues from the smoke plumes, potentially leading to respiratory illnesses and increased cancer risk. Health experts warn that the combined effects of the oil fires and the black rain could have devastating consequences for the local population. The situation highlights the urgent need for effective measures to mitigate the environmental and health impacts of such disasters.
