Short-Term Effects of Airport-Associated Ultrafine Particle Exposureon Lung Function and Inflammation in Adults with Asthma

摘要

Background:Exposure to ultrafine particles (UFP, particles with aerodynamic diameter less than 100nm) is associated with reduced lung function and airway inflammation in individuals with asthma. Recently, elevated UFP number concentrations (PN) from aircraft landing and takeoff activity were identified downwind of the Los Angeles International Airport (LAX) but little is known about the health impacts of airport-related UFP exposure.
