Fig. 2: Targeted and non-targeted analysis identify elevated VOCs within and outside the evacuation zone.

From: The application of PTR-MS and non-targeted analysis to characterize VOCs emitted from a plastic recycling facility fire

Fig. 2

A EPA targeted analysis of benzene and hydrogen cyanide (HCN) within the evacuation zone between April 12–15th, 2023. B Targeted detection levels of benzene across sampling site visits on April 15th, 2023. C Non-targeted estimated detection levels of hydrogen cyanide across sampling site visits on April 15th, 2023. D Non-targeted analysis of VOCs within and outside the evacuation zone with estimated average levels at least 1.8-fold higher than background (site 0) levels. The numerical fold change value is shown for compounds that exceeded a 5-fold increase.
