With increasing industrialization, numerous air pollutants are generated. This research aimed to investigate the effects of inhalation of oxidative pollutants. H_2O_2 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. H_2O_2 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 biom...
