[Comparison of Characteristics and Source Apportionment of Polycyclic Aromatic Hydrocarbons in Different Environmental Media in the Urban Area of Daqing City].

In order to investigate the various pollution characteristics and sources of polycyclic aromatic hydrocarbons (PAHs) in different environmental media, 23 street dust samples and four soil samples were collected in October 2012 in Daqing City. After extraction by Dionex ASE300 and purification, the content of the US EPA priority pollutants[16 individual PAH and total PAHs (ΣPAHs)] was determined by using gas chromatography-mass spectrometry (GC/MS). The results showed that the range of ΣPAHs content in street dust was 579.
