AB  - A method was established for the simultaneous determination of 23 volatile 
      organic compounds (VOCs) in ambient air with combination of thermal desorption 
      (TD) and gas chromatography-triple quadrupole tandem mass spectrometry 
      (GC-MS/MS). The air samples were collected by active sampling method using 
      Tenax-TA sorbent tubes, and desorbed by thermal desorption. The analytes were 
      determined by GC-MS/MS in selected reaction monitoring (SRM) mode, and internal 
      standard method was applied to quantify the VOCs. The results of all the 23 VOCs 
      showed good linearities in low level (0. 01-1 ng) and high level (1-100 ng) with 
      all the correlation coefficients (r2) more than 0. 99. The method quantification 
      limits were between 0. 000 08-1 microg/m3. The method was validated by means of 
      recovery experiments (n = 6) at three spiked levels of 2, 10 and 50 ng. The 
      recoveries between 77% and 124% were generally obtained. The relative standard 
      deviations (RSDs) in all cases were lower than 20%, except for chlorobenzene at 
      the low spiked level. The developed method was applied to determine VOCs in 
      ambient air collected at three sites in Shanghai. Several compounds, like 
      benzene, toluene, ethylbenzene, m-xylenes, p-xylenes, styrene, 1, 2, 
      4-trimethylbenzene and hexachlorobutadiene were detected and confirmed in all the 
      samples analyzed. The method is highly accurate, reliable and sensitive for 
      monitoring the VOCs in ambient air.
