Figure 7

ROS formation in BEAS-2B cells. Cells were exposed for 2 h to 7.5 μg/cm2 of winter PM2.5 and to the equivalent amount of organic fraction and of washed particles. The results are reported as fluorescence arbitrary units (mean ± SEM of 3 independent experiments). * Statistically significant difference from untreated cells (control), P < 0.05.
