Last week the American Lung Association released their State of the Air 2013 report, a (forgive the pun) breathtaking look at levels of ozone and particle pollution found in official monitoring sites across the United States.
According to the report, more than 131 million people (a full 42% of the U.S. population) live in counties that have unhealthy levels of either ozone or particle pollution. Are you in one of them? Visit http://www.stateoftheair.org/ and enter your zip code to see how your area stacks up.
If your county doesn’t make the grade, don’t despair: Check out Environmental Defense Fund health scientist Elena Craft’s tips for protecting yourself against ground level ozone, or smog, pollution. Your lungs will thank you.
