They aren't comparable at the moment. But London used to have "London fogs" that contained a large air pollution component. At least one was so bad that a doctor hired a blind man to guide him on his house visits, since the doctor couldn't see enough to tell where he was (even on foot on the sidewalk), but the blind guy wasn't handicapped at all by the smog.

Oh I know, I'm just clearing up some possible misconceptions, I think some people aren't aware just how bad pollution in China is right now. Even in tertiary cities there's significant smog. If their authoritarian government does one think I hope it makes fixing that a priority.
