Black-Pigmented Material in Airway Macrophages from Healthy Children: Association with Lung Function and Modeled PM10

Research Report 134,
2008

Research Report 134 describes a study that evaluated whether there was an association between particles detectable in the airways of healthy children and a) estimates of local, traffic-derived PM10 at the children's home addresses or b) their lung function. Dr. Jonathan Grigg and colleagues recruited 116 healthy children aged 8 to 15 years who lived in Leicester, UK. In addition to modeling each child's exposure, the investigators measured lung function and evaluated induced sputum for particles in airway macrophages and markers of inflammation.
