Abstract
Subjects were exposed to different concentrations of CFC-113 for variable duration while conducting 30-minute exercise regiments. End-exhaled breath samples were collected 25, 30 and 35 minutes after the exercise regiment and quantified using gas chromatography. Three comparative studies were conducted.;A short duration administration delivered at the beginning or at the end of the regiment was compared to a long duration administration delivered at the beginning or at the end of the exercise regiment. The second study compared breath samples when 500 ppm of CFC-113 was administered at the beginning or end six minutes of the regiment. The third compared continuous exposures (30 min of 100 ppm) to intermittent exposures (three intermittent 2-min exposures of 500 ppm). This study determined that equivalent doses of CFC-113 administered with variable exposure profiles to human subjects produced statistically equivalent end-exhaled CFC-113 concentration, except in two cases.
