Rezumat:

Honey and propolis samples from different flowering plants in 15 regions of Romania, collected from beekeepers and the local market
during the period 2002–2005, were analyzed to detect 15 polycyclic aromatic hydrocarbons (PAHs). An analytical procedure based on
previous liquid–liquid extraction (LLE) with hexane, after which the extract was cleaned up in a mixture of silica gel, aluminum oxide
and anhydrous sodium sulfate column, has been developed. The fractions eluted from the columns were further analyzed by gas
chromatography with mass spectrometric detection (GC–MS). The limits of detection ranged from 0.03 to 0.12 mg/kg. Some PAHs were
detected in honey and propolis samples within the range 0.6–665.0 ng/g, and some PAHs were not detected or were under the detection
limit of the method. Thus, consumers should not be concerned about PAHs in Romanian honey and propolis.
