You might be saying, “oh great, another list from Down To Earth."  And that’s what I thought when it was emailed to me too - but there’s a lot of interesting information to look at here. After all, you can't be too careful with the air you breathe.

The American Lung Association (ALA) has released their annual report, State of the Air 2011, highlighting which cities have the worst air for ozone pollution, short-term particle pollution, and year-long particle pollution.

This slideshow highlights the top cities ranked in the their "10 Cities Most Polluted by Year-Round Particle Pollution." According to the report, over 18.5 million people in the U.S. live in a region with unhealthy levels of year-round particle pollution.

According to the ALA, particle pollution from power plants kills approximately 13,000 people per year.

The worst offender? Los Angeles.

Here are their stats:

Total Population: 17,820,893
Under 18: 4,682,410
