With increasing industrialization, numerous air pollutants are generated. This research aimed to investigate the effects of inhalation of oxidative pollutants. H2O2 was used to simulate oxidative air pollutants, and glutathione, a reducing agent that is widely distributed in organisms, was used as an antagonist, to protect cells from oxidative stress. H2O2 was diluted using two gradients (0.05 mM, 0.20 mM, 0.80 mM, 3.20 mM and 0.05 mM, 0.10 mM, 0.15 mM, 0.20 mM) and GSH was dissolved at 20 μM. MTT, MDA, ROS, GSH, and TSLP were used as biomarkers to evaluate oxidative stress and possible resulting molecular events. A dose–response relationship was observed between H2O2 concentrations and the above-mentioned biomarkers. Glutathione significantly reduced levels of oxidative stress.
