AB  - A novel method for the analysis of four polybrominated diphenyl ethers (PBDEs) in 
      environmental and human serum samples based on hollow fiber-liquid phase 
      microextraction (HF-LPME) followed by gas chromatography-inductively coupled 
      plasma mass spectrometric (GC-ICP-MS) detection has been developed. The organic 
      solvent in the porous hollow fiber was first dipped into the sample for 
      extraction at a given time, and the retracted organic phase was introduced into 
      the GC-ICP-MS for analysis. The addition of methanol has a strong effect on the 
      HF-LPME extraction efficiency. Other significant parameters affecting the 
      extraction efficiency of HF-LPME were also studied. HF-LPME was effective to 
      isolate the analytes from the complex matrix. Under the optimized conditions, the 
      detection limits of the proposed method varied from 15.2 to 40.5 ng/L. In 
      general, the relative standard deviations (RSDs) were less than 10%. Good 
      linearity was obtained with the correlation coefficients all better than 0.999. 
      The proposed method is simple, quick, few microliters of organic solvent 
      required, and is especially suitable for the analysis of the real sample with 
      small amount available. The overall process of HF-LPME with GC-ICP-MS was applied 
      successfully for the determination of polybrominated diphenyl ethers (PBDEs) in 
      environmental and spiked human serum samples, and the results were satisfactory.
