AB  - A high performance liquid chromatography-electrospray ionization-mass 
      spectrometry (HPLC-ESI-MS) method was developed for the determination of 
      hexabromocyclododecanes (HBCDs) in ambient air samples. The samples were 
      extracted by Soxhlet extractor with hexane, then purified on the composite gel 
      column. At first, the interfering substances were rinsed with 50 mL hexane and 
      100 mL hexane-dichloromethane (9:1, v/v), then 180 mL hexane -dichloromethane 
      (4:1, v/v) was used to elute the targets. The compounds were separated by 
      gradient elution with acetonitrile-methanol-water as mobile phases on a UF-ODS 
      column (150 mmx2.1 mm, 3.0 mum). Electrospray ionization negative ion source and 
      selective ion monitoring (SIM) mode were adopted in MS detection. The results 
      showed that alpha -HBCD, beta -HBCD and gamma -HBCD could be well separated, and the 
      chromatographic peak area ratio of alpha -HBCD, beta -HBCD and gamma -HBCD to internal 
      standard D(18)- gamma -HBCD with their concentrations had a good linear relationship, 
      with the correlation coefficients (R) >/= 0.9988. The limits of detection (LODs, 
      S/N=3) of alpha -HBCD, beta -HBCD and gamma -HBCD were 0.4, 0.5 and 0.4 mug/L, respectively. 
      The limits of quantification (LOQs, S/N=10) were 1.4, 1.6 and 1.3 mug/L, 
      respectively. The method detection limits (MDL) were 0.13, 0.17 and 0.13 pg/m(3) 
      (n=5), respectively. The recoveries of HBCDs spiked in the actual air samples 
      were in the range of 74.8%-95.8%. It is demonstrated that the method has high 
      sensitivity and good selectivity, and can meet the requirement of monitoring and 
      analyzing HBCDs in air samples.
