AB  - A new method has been developed for the determination of selected polybrominated 
      diphenylethers (PBDEs) and polybrominated biphenyl (PBB) in four polymers: 
      high-density polyethylene (HDPE), polystyrene (PS), 
      acrylonitrile-butadiene-styrene copolymer (ABS), and polypropylene (PP). PBDEs 
      and PBB in the polymers were extracted with toluene, using ultrasonic-assisted 
      extraction (UAE). The extracts were then determined by high-performance liquid 
      chromatography-inductively coupled plasma mass spectrometry (HPLC-ICP-MS), using 
      external calibration (single-point). Extraction parameters of UAE and several 
      ICP-MS parameters were optimized. Extraction efficiencies almost reached 100%. 
      The relative standard deviations (RSDs) were in the range of 0.7%-5.4%. The 
      results demonstrate that the method possesses advantages of good precision, as 
      well as high extraction efficiency and accuracy. The method especially overcomes 
      the problem of the thermal degradation of highly brominated PBDEs, such as 
      PBDE-209.
