Dramatic improvements in air quality in U.S. cities since the 1990s may not be enough to ensure normal lung function in children, according to new research published in the April 15 American Journal of Respiratory and Critical Care, a journal of the American Thoracic Society.

In "Lifetime Exposure to Ambient Air Pollution and Lung Function in Children," researchers report that children exposed to higher levels of air pollution, including fine particulate matter (PM2.5) and soot (black carbon), had worse lung function than those living in less polluted areas. By age eight, the lung function of children living within 100 meters of a major roadway was on average 6 percent lower than that of children living 400 meters or more away.
