Determination of polycyclic aromatic hydrocarbons and their oxy-, nitro-, and hydroxy-oxidation products

► We describe a method for determining PAHs and their oxidation products. ► Solid-phase extraction was used to fractionate PAHs and their oxidation products. ► Gas chromatography-mass spectrometry methods were optimized. ► The developed method was applied to two particulate matter (PM) samples.
