Less pollution = improvement in children's respiratory health

A USC study that tracked Southern California children over a 20 year period has found they now have significantly fewer respiratory symptoms as a result of improved air quality. The finding expands on the landmark USC Children’s Health Study, which a year ago reported that kids’ lungs had grown stronger over the past 20 years as pollution levels in the Los Angeles Basin declined. In the current study, USC researchers examined a health issue that makes many parents anxious while pulling at their pocketbooks: bronchitic symptoms that could land otherwise healthy children in a doctor’s office or hospital.
