Study Summary
Purpose: The purpose of this protocol is to understand how individuals respond to the air pollutant ozone at elevated temperatures. Ultimately, this will help us understand what the risks from poor air quality are during a heat wave. Participants: We will recruit up to 30 healthy adults, 18-55 years old, to participate in this study. Procedures (methods): Subjects will be exposed to clean air and to 0.3 ppm of ozone for 2 hours with intermittent exercise in a controlled environment chamber. For each exposure the temperature in the chamber will be between 31-34oC (88-93 oF). Because the aim of the study is to mimic high exposure during a heat wave, we will perform exposures only on days when mean ambient temperatures was less than 24 oC in Chapel Hill on the previous day. Primary endpoints will include spirometry and Heart Rate Variability monitoring. Secondary endpoints will include analysis of blood clotting/coagulation factors, and analysis of soluble factors present in plasma.
