A: ozone exposure disrupts body weight gain and alters bronchoalveolar lavage fluid (BALF) immune cell counts. A: experimental design depicting exposure regimen and designated outcomes examined. B: increase (positive values) or decrease (negative values) in body weight over the 3 wk of exposure to filtered air or ozone. C: total cells recovered in 300 μL of the first two lavages from air- and ozone-exposed males and females. Error bars represent means ± SE. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001, using one-way ANOVA followed by the Tukey multiple-comparison post hoc test. (n = 13 or 14 per group). BALF, bronchoalveolar lavage fluid.
