Reply #1: I like the report, I didn't know Pittsburgh was in California

From the cite:
Dirt Devils
The nation's 10 most polluted cities by amount of particulates.
Metro area State Average particles level (2005-2007)
Bakersfield CA 20.3
Pittsburgh CA 19.8
Visalia CA 19.3
Birmingham AL 18.9
Hanford CA 17.6
Fresno CA 17.4
Cincinnati OH 17.3
Detroit MI 17.2
Los Angeles CA 17.1
Cleveland OH 16.

Now Pittsburg Ca does exist, but I doubt it was the city referred to in the article as:

"There's some criticism of the findings based on where the EPA monitoring stations are located. In Pittsburgh, for example, one station sits near the largest coke plant in the nation. Coke, an ingredient in steel manufacturing, is made by baking coal and produces lots of ash and other particles.

The "largest coke mill in the Country" is in Allegheny County PA whose county seat is Pittsburgh PA (I mean Pittsburgh CA, CNN can't be wrong).

Yes, we native Pittsburghers are proud of our H in the name of the City.

It would not be bad, but the Actual coke Works are in Clairton PA, an old River Town up the Monongahela River from Pittsburgh. Clariton is in the same County as Pittsburgh, but technically the Coke plant is NOT in the City of Pittsburgh:
