Initially we quantified and archived nine compounds employing our Uncooked TD-GC-MS information and reference UTRs (Markes Intercontinental, 2015). With all the UTRs derived inside our recent examine, a handful of vital compounds, which includes toluene and xylenes (all isomers) were being calculated from the original Uncooked mass sorbed onto these tubes . Other compounds weren't continuously detected or pertinent at our sampling web-site. Benzene and ethylbenzene concentrations have been when compared with All those derived Earlier from reference UTRs to our UTRs in Table 2 (see Figure three).
