Results from standard addition calibration of PAH species for the two filters from each city. Concentrations of higher-mass PAHs > 202.078 were found to be much more reliable due to their lower vapour pressure

*Reported values are too high due to intrinsic properties of the PAHs resulting in large calibration errors
