An analytical procedure based on solid-phase extraction, using ethyl acetate as the elution solvent, and high-performance liquid chromatography with fluorescence and diode array detection was developed for the identification and quantification of polycyclic aromatic hydrocarbons (PAHs) in honey. The method has been optimized and validated in accordance with Commission Regulation 333/2007 and Commission Decision 2002/657/EC. This method allows the identification of the 15 PAHs that should be monitored in food matrices, as proposed in 2002 by the Scientific Committee on Food and later by the European Union in the Commission Recommendation 2005/108/EC, because of their genotoxic and carcinogenic properties. The results of the validation study were in agreement with quality criteria described in European legislation in terms of sensitivity, accuracy, and ruggedness, and the method was applied to the analysis of 42 honey samples (21 from Spain and 21 from other regions). The honey samples were not contaminated by PAHs at detectable levels and thus could be marketed without health risk.

Based on the principle of solid phase extraction and the purification method using Florida silica, sixteen various kinds of polycyclic aromatic hydrocarbons such as naphthalene, acenaphthene and fluorene were measured in Urumqi snow by means of HPLC. The results showed that the concentration of PAHs was different in different sampling sites in Urumqi. The total concentration of PAHs was in the range of 0.2883 ~ 8.814 µg/mL and the content of PAHs snow was higher than that in water, which indicated that the snow was polluted by organic matters to a certain degree and the pollution was not so serious compared with the groundwater. So the snow has a certain application value for life.
