Table 1.
Calculated log K fs and m f values for ten exemplary PAHs included in this work, determined for a SPME fiber (100 μm × 10 mm, 0.6 μL), a PAL SPME Arrow (250 μm × 20 mm, 10.2 μL), and an SBSE bar (500 μm × 20 mm, 47 μL) for a c 0 of 10 ng L−1, sorted by ascending log K fs value, based on solute descriptors from literature [23]
