This trial is testing how different environmental and genetic factors may affect lung function. It will screen participants over the course of one day, then have them come back for two days for more testing. This will include a blood draw and a breathing test before and after being exposed to either filtered air or ozone. Then, they will have a bronchoscopy to evaluate the lungs. They will repeat this process once more, 18-20 days later. There will be follow-up phone calls from the study team after each two-day test series. The whole study will last one to one-and-a-half months.
