Smoggiest cities for 2007
Not surprisingly, Los Angeles is listed as the smoggiest major city in the United States. This is based on a report released today by the American Lung Association. Yet LA is much better than it was 20 years ago before the strict smog laws (if you can imagine that). I remember feeling a burning in the throat on hot summer days if you spent any time outside anywhere near the inland empire. It is surrounded by mountains and the onshore air currents would pin the smog in the valley.
Miami shows up as the city with the cleanest air. Of course, this is largely because it is flat area with no mountains to hold these pollutants in. Combined with the vast presence of water gives Miami a certain advantage over other US cities.
The 10 most polluted are (population 1mil+):
- Los Angeles, CA
- Pittsburgh, PA
- Fresno, CA
- Birmingham, AL
- Salt Lake City, UT
- Detroit, MI
- Cleveland, OH
- Washington, DC

The 10 cities with the cleanest air are (population 350K+)

How can Phoenix have clean air? Phoenix has high smog and Ozone alerts every winter and summer - it’s so bad that you can’t use your fireplace during the cold winters or use a leaf-blower. Phoenix has a term they call “Brown Cloud” every winter because of the air they can see that they breathe. Please update your information - there is no way Phoenix has clean air.
