NOW ON YOUR MOBILE DEVICE: WHY YOU CAN’T BREATHE A team comprising researchers at UH, Air Alliance Houston, and the American Lung Association have launched OzoneMap, an app that “monitors chemical weather,” reports John Metcalfe of The Atlantic blog Cities. And whether the app helps explain your coughing fit or alerts you to the chance of a really pretty toxic sunset, the best part is that it’s only available in Houston! And why Houston, of all places? Besides the industrial flares, that is? Here’s Metcalfe: “The Houston/Baytown/Huntsville region comes in eighth place for most ozone-polluted cities in America, as ranked by the American Lung Association. Persistently sunny weather, a battalion of petrochemical facilities and scads of fuming cars on the road make Houston a nightmare for anyone who’s chemically sensitive. For these folks, walking outside is like playing a lower-stakes version of Russian roulette, with 30 to 40 days of the year fogged with hazardous levels of ozone.” [Cities; previously on Swamplot] Map: Cities
