Listed here, BTEX compounds ended up employed for instance of urban VOC emissions and benzene/toluene ratios and PM2.5 as opportunity wildfire smoke markers. Originally we quantified and archived nine compounds using our raw TD-GC-MS info and reference UTRs (Markes International, 2015). With the UTRs derived within our existing review, a number of vital compounds, which include toluene and xylenes (all isomers) had been calculated from the initial Uncooked mass sorbed onto these tubes . Other compounds were not constantly detected or relevant at our sampling site. Benzene and ethylbenzene concentrations were being in comparison with People derived Formerly from reference UTRs to our UTRs in Table two (see Figure 3).
