A chemical analysis of air samples taken from California's San Joaquin Valley and an Oakland traffic tunnel show that diesel fuel emissions are more polluting than previously thought, according to researchers.

The pollutant is a major element of smog and can contribute to heart and respiratory problems. http://www.latimes.com/news/science/sciencenow/la-sci-sn-diesel-pollution-20121022,0,7643604.story?track=rss
