I like some of the California (CARB) particulate data:

Most of the highest PM10 levels occur where?  In the deserts (blowing
dust, especially in the Owens Valley where LA has siphoned off all the
surface water) and the mountains (darn pine trees and the haze they
produce).  I guess reducing the added particulates from diesel and
gasoline is a good thing, but particulates won't be eliminated.
