From: Diesel exhaust but not ozone increases fraction of exhaled nitric oxide in a randomized controlled experimental exposure study of healthy human subjects

Figure 1

FENO responses after exposure to diesel exhaust and ozone. a) Exposure to diesel exhaust for one hour increased the fraction of exhaled nitric oxide (FENO) compared to filtered air at expiratory flow rates of FENO10 [60.8 ± 6.0 vs. 50.2 ± 5.9 ppb repeated measures ANOVA P = 0.01] and at FENO50 [18.6 ± 1.6 vs.15.9 ± 1.5 ppb repeated measures ANOVA P = 0.011]. b) Exposure to ozone for one hour did not alter FENO concentrations compared to filtered air at expiratory flow rates of FENO10 and FENO50.
