Effects of ozone and nitrogen dioxide on lung function in healthy and asthmatic adolescents. Research report, April 1983-April 1987
This project investigated whether or not well-characterized groups of healthy adolescents and adolescents with asthma differed in their sensitivity to ozone and nitrogen dioxide (NO/sub 2/). During Phase I, pulmonary function was not consistently altered in either the asthmatic or the healthy adolescents with these exposures. In Phase II, small but significant increases in total respiratory resistance to all test atmospheres were seen, after exposure at 0.12 ppm during 10 minutes of exercise, in both healthy and asthmatic adolescents, but were not statistically different between the groups. In Phase III, statistically significant changes were seen in average total respiratory resistance values in both healthy and asthmatic adolescents exposed to 0.18 ppm ozone while exercising. Again, the difference between the groups was not significant.
