Principal Investigator:

Philip Bromberg, MD


Ozone is a common air pollutant. The level of ozone in the air during warmer seasons in many parts of the country can be as high as 0.07 parts per million (ppm) or even higher for a short period of time. Several recent studies have reported that exposure to ozone air pollution may increase risk of heart disease. These reports have raised concern about whether the amount of ozone allowed to be in the air we breathe should be lowered. The U.S. Environmental Protection Agency (EPA) needs additional information from studies of people like you (healthy, between the ages of 55 and 70) to better understand how ozone might affect the heart and blood vessels

A total of 40 people will participate in this study at this site.
