PM2.5 exposure-induced oxidative damage inhibits the viability and induces the apoptosis of BEAS-2B cells. BEAS-2B cells were exposed to various concentrations of PM2.5 for 24 h. (A) Cell viability was analyzed by CCK-8 assay. Cell apoptosis was evaluated by (B) flow cytometry and (C) Hoechst 33258 staining. (D) Intracellular ROS production was examined using the fluorogenic dye, DCFH-DA. Data are presented as the means ± SD; n=3, **P<0.01 compared with the control (0 mg/ml). PM2.5, fine particulate matter.
