Abstract


Several honey samples from Cluj County and one sample from its territorial limit were investigated in order to establish their contamination degree in relation with polycyclic aromatic hydrocarbons (PAH) and heavy metals. High Performance Liquid Chromatography (HPLC) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) techniques were used in order to perform the proposed analysis. The HPLC analysis showed that the investigated honey samples have close concentrations of PAH. Benzo[a]pyrene, the representative marker of PAH in food have a concentration lower than limit of detection. Low concentration of heavy metals (As, Cd, Pb and Sr) in honey samples were obtained by ICP-MS analysis. The obtained results suggest that the investigated honey samples are appropriate for human consumption.
