Notes:
↵1 Obtained from GC/MS (derivatized) chromatograms; concentrations estimated via an internal standard.
↵2 Obtained from LC/UV/MS chromatograms; concentrations estimated from a calibration curve versus an authentic standard.
3ND = not detected.
↵4 The actual UV absorbance was measured on a diluted sample. These results represent the values adjusted for dilution.
↵5 This represents the total peak area of peaks in the LC/MS + ion total ion current (TIC) chromatograms that were attributed to ELO-related extractables. Although the reported data is in area response units and not concentration units, the data is adequate to show trends in accumulation.
