Figure 2. Hierarchical clustering of top 50 most abundant features detected by LC-IMS-MS.

Figure 2.

Heatmap shows the relative abundance of the top 50 features obtained from Mass Profiler (ver. B.08.01) for all open water (SCW1–5) and shore-access (Baytown Nature Center, BNC; Lynchburg Ferry, LF; Morgan’s Point, MP; River Terrace Park, RTP) surface water samples across all time points (April–August 2019). See SI Table 2 for sample location information. Open water samples were not collected in August. Seven PFAS species (labeled above map) were identified within the top 50 features. See SI Table 7 for data used to create this heatmap.
