This paper proposes a simple HPLC method for the determination of polycyclic aromatic hydrocarbons (PAHs) in water, wine and beer. Samples were purified by PAH collection in solid-phase extraction (SPE) and analysed by reversed-phase HPLC (Supelcosil LC-PAH column from Supelco). For the beer sample, recoveries amounted to 28% for naphthalene and varied from 57% to 103% for the other PAHs; results are quantitative starting from fluoranthene (FI, the seventh component eluted). Almost all the beer and wine samples showed the presence of benzo(b)fluoranthene (BbF), benzo(k)fluoranthene (BkF), benzo(a)pyrene (BaP), benz(ghi)perylene (BghiP) and indeno(1,2,3-cd)pyrene (IP), and in some cases there were traces of FI, benzo(a)anthracene (BaA) and dibenz(ah) anthracene (DBahA). Total contents of PAHs ranged from trace amounts to 0.72 ppb. Traces of BbF, BkF, BaP, BghiP and IP were also found in the wine samples.
