On Saturday, Mohammadreza Pir-Cheraghali, a fuel expert of the Iranian regime, said: “The main cause of air pollution in Iran’s mega cities is the diesel fuel produced domestically.”
“The reason for the air pollution, especially in winter, is the heavy hydrocarbons produced in oil refineries and petrochemical complexes that reach consumers as diesel fuel,” he said.
There have been 18 straight days of dangerously polluted air in Tehran.
