I did grad school in SLC and they suffer from the same geographical/topological problems as Beijing: both cities are basically bowls trapped in by mountains on all sides, where wicked inversions often occur in the winter that trap pollution in with no relief until the winds blow in. Now for this from the article:
> For weeks, industrialized cities in northern China have been dealing with bouts of sickening smog several times more toxic than Utah's. But by U.S. standards, Utah's pollution index is off the charts with readings routinely exceeding a scale that tops out at 70 micrograms a cubic meter. The EPA sets a standard for clean air at no more than 35 micrograms.
70 AQI, talk about first world problems! Right now in Beijing its around 90, and that is considered very good for us! Last night was 486, and I was crazy enough to go for a walk. Many of us laowai in Beijing get depressed in the winter because of the poor air quality.
