AB  - A fast method for determination of polycyclic aromatic hydrocarbons (PAHs) in 
      water samples was established. The samples from the Dianchi Lake and Panlong 
      River were analyzed directly using stir bar sorptive extraction-thermal 
      desorption system-gas chromatography/ mass spectrometry (SBSE-TDS-GC/MS). 
      Polydimethylsiloxane (PDMS) was used as the extraction phase. The samples were 
      extracted with stir bars at 1100 r/min for 60 min at ambient temperature (25 
      degrees C). Desorption was carried out at 300 degrees C for 5 min under a helium 
      flow of 50 mL/min in the splitless mode while maintaining a cryofocusing 
      temperature of 0 degrees C in the programmed-temperature vaporization (PTV) 
      injector of the GC/MS system. The limits of detection of PAHs ranged from 1.0 pg 
      to 468.8 pg. The theoretical recoveries of PAHs were greater than 90% (except 
      that naphthalene was 64.90%), and the recoveries of 16 PAHs from water samples 
      ranged from 83.1% to 109.4%, and the relative standard deviations (RSDs) ranged 
      from 1.2% to 9.3% (n = 6). PAHs in Dianchi Lake and Panlong River samples were 
      quantified rapidly by this method. The results show that, the total content of 
      these 16 PAHs is 89.16 ng/L in Dianchi Lake, 65.41 ng/L in the up-stream of 
      Panlong River, 339.22 ng/L in the middle-stream of Panlong River and 62.25 ng/L 
      in the down-stream of Panlong River. It is demonstrated that the Dianchi Lake and 
      Panlong River were polluted by PAHs to some degree.
