AB  - A method for the determination of 39 polychlorinated biphenyls (PCBs) in indoor 
      dust was developed. A vacuum cleaner was used for gathering the house dust. 
      N-Hexane-dichloromethane (1: 1, v/v) was added and the extraction was performed 
      in an ultrasonic bath. The supernatant was concentrated and then 0.1 mL 
      n-hexane-dichloromethane (1: 1, v/v) was added. Gas chromatography-tandem mass 
      spectrometry (GC-MS/MS) in selected-reaction monitoring (SRM) mode has been 
      investigated for the determination of the 39 PCBs congeners in indoor dust. The 
      39 PCBs had highly efficient separation within 30 min and showed good linearity 
      in the range of 0.1 - 100 microg/L with the correlation coefficients of 0.991 0 - 
      0.999 9. The spiked recoveries were 57.2% - 120.3%. The intra-day relative 
      standard deviations (RSDs) were between 0.3% and 24.7%, while the inter-day RSDs 
      were between 0.6% and 29.9%. This method has good linearity, high sensitivity, 
      high accuracy and precision. Also, it is simple, rapid and low solvent 
      consumption. The low chemical background interference allowed it to be used in 
      more complex matrices.
