This week on The Allegheny Front, stories about the air we breathe: neighbors of an industrial coke plant say a recent fire there has made air pollution worse in their community; a new book looks at air pollution from a global perspective. Plus, the story of a Pittsburgh environmental group that started in the 1960s with a guerrilla marketing campaign and outrage over smoky skies.
On many days, Pittsburgh's air pollution is hard to ignore. Even with recent improvements in air quality, Allegheny County still does not meet federal air quality standards for fine-particulate pollution. Photo: Matt Niemi via Flickr
