10-1 Cardiovascular Effects of Exposure to Low Levels of Ozone in the Presence or Absence of Other Ambient Pollutants

Not Active
RFA 10-1

Two types of studies are sought to evaluate cardiovascular and respiratory effects in healthy human volunteers, aged 55 and above. In Phase 1, volunteers will be exposed to ozone alone, at concentrations between 60 and 100 ppb, in a controlled laboratory setting. In Phase 2, volunteers will be exposed to real-world ambient air pollution at sites with ozone concentrations comparable to those used in Phase 1. Interested scientists may apply for Phase 1, Phase 2, or both.

HEI Research Report 192 describes a multicenter study by John Balmes at the University of California–San Francisco, Phil Bromberg at the University of North Carolina–Chapel Hill, and Mark Frampton at the University of Rochester, New York. The study was designed to test whether ozone has short-term cardiovascular effects at present-day ambient levels. It evaluated respiratory and cardiovascular outcomes in 87 healthy participants (60 years old on average) who were exposed to 0, 70, or 120 ppb ozone for 3 hours while exercising moderately.
