Asthma & Exposure to Peaks in Particulate Air Pollution

NCT00013728 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 24

Last updated 2006-03-23

No results posted yet for this study

Summary

We are testing the following two hypotheses: 1) Peaks in hourly exposures to airborne particulate matter (PM) of outdoor origin will be more closely associated with acute asthmatic responses to particles than 24-hour average exposures in susceptible individuals; 2) Personal exposure to PM, and estimated particle dose to the lungs, will be more closely associated with daily asthma severity than standard outdoor particle concentrations measured as 24-hour averages at governmental monitoring sites.
