their poor desorption from the Carbograph 2TD/1TD tubes, the data for acenaphthene, fluorene, and anthracene was omitted from the plots. The 6/15/16 plots show the tightest distributions among the PAHs with the fewest outlier measurements, indicating good reproducibility in the measurements. The calibration levels (1-8) correspond to the following PAH amounts: 0, 0.02, 0.05, 0.1, 0.2, 0.5, 1, and 2 ng. Figure S5a: Figure S5b:
