Researchers from UC Davis have found a closer link between bronchitis in infants and some gases and particles in air pollution, findings that bolster efforts in the Sacramento region to control emissions from vehicles and wood-burning stoves.
In one of the first studies to look at air pollution and infants, researchers said last week they found young lungs more vulnerable to little-studied components in air pollution called polycyclic aromatic hydrocarbons, or PAHs. Such contaminants get into the air from coal burning, vehicle exhaust, wood-burning stoves and tobacco smoke, and from grilling food.
"Our work suggests that regulators consider efforts to curb PAHs as well," lead researcher Irva Hertz-Picciotto said in a statement.
