Table 2.

Concentrations of PAHs present in real-world samples. The table lists 15 PAHs, most of which are U.S. EPA priority PAHs, and gives the PAH concentration in nanogram per milliliter concentration. This table also calculates the nanogram PAH concentration at the highest dose tested 10 μg/mL OC. The last two rows of the table represent the average PAH concentration and the total sum of PAH concentration. Motor oil is not included in this table because it does not contain any PAHs.
