Abstract

A rapid method for the determination of PAHs in soil samples based on their extraction with methylene chloride by sonication and subsequent separation by HPLC with fluorimetric detection is proposed. A Hypersil Green PAH column was used with a gradient of acetonitrile/water as the mobile phase, together with a program of nine excitation and emission wavelength pairs. Recoveries were in the range 70–98%, except for acenaphthene and naphthalene, at concentration levels 1.08–442 μg/kg with relative standard deviations in the range 2–15% (n = 4). Total PAHs found in soil samples were in the range 15–282 μg/kg. The results were compared with those obtained by applying the 3540 EPA method for two samples.
