INTRODUCTION
Polycyclic Aromatic Hydrocarbons (PAHs) are prevalent in the environment. They either occur naturally in fossil fuel products (e.g., coal and oil), or amon the effluents of combustion processes commonly usedfor heating, incineration, and electric power generation
PAHs are classified as carcinogenic compounds and consequently are monitored worldwide in a wide range of environmental matrices, including drinking water,waste water, furnace emissions, soil, and hazardouswaste extracts.Methods for the determination of PAHs in the
environment include gas chromatography with flame ionization detection (GC/FID) and high-performance liquid chromatography (HPLC) with ultraviolet or fluorescence detection. While GC/FID is the more
sensitive technique, it is subject to background interfer-ences from other carbonaceous sources. HPLC is the preferred method of analysis, because it provides the necessary sensitivity in combination with higher specificity. This application note presents two different reversed-phase high-performance liquid chromatogra-
phy (RP-HPLC) methods for the determination of PAHs in extracted environmental samples.
