Oxidative potential of subway PM2.5 - ScienceDirect

01/01/2017 · Chemical compositions of the subway PM 2.5 samples are provided on Table 3, based on averages of 6 samples per station (similar values are presented for average values for 30 days campaigns in Martins et al., 2016a; in agreement with the representativeness of the samples selected for this study). These results show high concentrations of Fe, Total Carbon (TC), Ba, Cu, Mn, Zn and Cr, all

Organophosphate esters in airborne particles from subway

The mean concentrations of OPEs in PM2.5 samples collected from different subway stations in Barcelona (Spain) are summarized in Table 2 (for individual sample results see Supporting information, Table S5). OPEs were detected in all the analysed samples, indicating widespread contamination by these emerging pollutants, with levels ranging between 1.59 and 202 ng/m 3 (mean value of 39.9 ng/m 3).
