The method using soxhlet extraction pretreatment and gas chromatography-triple quadrupole mass spectrometry to analyze 15 compounds of PAHs in Ambient Air has been established. The method detection limit was 0.008~0.071μg/mL for liquid condition,The RSD range of blank matrix spike was from 1.1%~9.3%,the average recovery was from 89.4%~113%;The method was used to analyze air samples and a comparative analysis with the result of GC-MS was done. The result proved that this method had high selectivity and precision,it can be applied to the determination of polycyclic ar?omatic hydrocarbons in ambient air.
