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.
