I didn’t know that. I looked it up and saw you’re right source
I will say that my worst experience was in Dehli India, which is currently twice as worse as Tehran! The air pollution in Dehli was so bad you could visually see hanging in the air, indoors at the airport. It was surreal to be walking around the terminal with the heavy smell of diesel exhaust as though you were surrounded by heavy trucks idling around you.
Tehran’s one of the world’s most polluted cities, so smog would be my bet. It’s a gorgeous look though!
