      polychlorinated dibenzo-p-dioxins and -furans and planar polychlorobiphenyls in 
      milk].

AB  - Since the chemical nature and toxicity of planar polychlorobiphenyls (PCBs) are 
      similar to those of polychlorinated dibenzo-p-dioxins and -furans (PCDD/Fs). 
      Dioxin-like PCBs and PCDD/Fs are often surveyed together in their exposure 
      assessments. The analysis of PCBs and PCDD/Fs in breast milk is specially 
      emphasized by World Health Organization (WHO) due to their severe toxicity. The 
      development of a method for the simultaneous analysis of PCBs and PCDD/Fs in milk 
      samples is invaluable. In this work, three certified milk powder materials with 
      different PCDD/Fs levels were Soxhlet-extracted and then cleaned up using 
      Power-Prep system automatically. PCDD/Fs and planar PCBs were determined using 
      isotope dilution and high resolution gas chromatography-high resolution mass 
      spectrometry. The determined values of 17 PCDD/Fs were consistent with the 
      certified values and the relative standard deviations (RSDs) of the determined 
      values were less than 20%. The recoveries of 13C labeled PCDD/Fs and planar PCBs, 
      and their RSDs were within the ranges specified in EPA1613 and 1668a methods, 
      respectively. Meanwhile, the analytical results of breast milk in an 
      interlaboratory comparison showed that this method has good reproducibility 
      between different laboratories. An accurate and reliable method was successfully 
      developed and can be used in the simultaneous analysis of PCDD/Fs and planar PCBs 
      in milk.
