Scientists have found that soot leads a “<a href="http://www.prx.org/pieces/99993#description">secret life</a>” after being released into the air, during which it picks up gases and other poisonous hitchhikers.&nbsp; Before the soot actually enters the lungs these particles go through a unique evolution that involves a surprising combination of molecules.</p><p> Wed, 24 Jul 2013 21:51:31 +0000 Katherine Blackley 13680 at http://wesa.fm Tracking the "Secret" Life of Soot EPA School Flag Program Monitors Pittsburgh Region’s Air Quality http://wesa.fm/post/epa-school-flag-program-monitors-pittsburgh-region-s-air-quality <p>The Group Against Smog and Pollution (GASP) and the federal Environmental Protection Agency are partnering on the so-called School Flag Program, which debuted last week at the Environmental Charter School at Frick Park.</p><p>“The School Flag Program was developed by the EPA, and it’s an engaging, hands-on way for students to inform their entire school and community about the region’s air quality and then to take necessary steps to minimize their exposure to high levels of air pollution,” said Karrie Kressler, of GASP.</p> Tue, 28 May 2013 15:34:16 +0000 Deanna Garcia 10321 at http://wesa.fm EPA School Flag Program Monitors Pittsburgh Region’s Air Quality Pittsburgh Air Is Getting Cleaner, But It's Still Dirty http://wesa.fm/post/pittsburgh-air-getting-cleaner-its-still-dirty <p>Pittsburgh’s air has gotten cleaner, but the city still ranks as one of the most polluted in the country.</p><p>That's according to the American Lung Association’s annual <a href="http://www.stateoftheair.org/2013/">State of the Air report</a> released Wednesday. According to the report, Pittsburgh ranks eighth in year-round particle pollution, the mix of tiny solid and liquid particles in the air. These particles can increase the risk of heart and lung disease and adverse birth outcomes.</p> Wed, 24 Apr 2013 18:49:17 +0000 Jared Adkins 8405 at http://wesa.fm
