Pollution Superheroes

My imagination has been running wild vividly envisioning the duel of two super-heroes, the clash of an irresistible force against an immovable force, like Superman versus a black hole. Well, that was just to help you get a sense of magnitude for my real query, wondering which city has worse air pollution: Mexico City or Kathmandu. Without getting into an ecological study I imagine that both cities could compete well for the title. Mexico city is considered to be among the world’s worst cities for air pollution because of its location surrounded by tall mountains. Its position locks in all the smog, fire and dust from the city and perpetually keeps the skies in Mexico city a thick brown haze. I believe the conditions would be the same if the perimeter of Kathmandu were also lined with inescapable mountain passes.
