Of this list, I've only been to China. Seeing it only ranks 19th is kinda scary. Smog is pretty rough there in even medium sized cities.

If you look closely, this is specifically gauging PM 2.5, or the very fine (and therefore dangerous) particulate matter. Most smog is generally larger particulates, PM 10, etc. I imagine China would probably rank higher on a more expansive list.
