      rural areas in South China.

AB  - Human nails have been increasingly used as a biomarker for human exposure to 
      persistent organic pollutants (POPs). In the present study, the fingernails of 
      e-waste-dismantling workers from Longtang town, Qingyuan city, rural residents 
      from Shijiao town, Qingyuan city, and urban residents from Guangzhou city, 
      respectively, were collected from South China to monitor the human burdens of 
      polybrominated diphenyl ether (PBDEs) and polychlorinated biphenyl (PCBs). The 
      median concentrations of in the nails of the e-waste-dismantling workers, and 
      urban and rural residents were 412, 129, and 82.1 ng g(-1), respectively, and the 
      median concentrations of were 108, 8.4, and 22.1 ng g(-1), respectively. The 
      levels of PCBs and PBDEs in the nails of e-waste-dismantling workers were 
      significantly higher as compared to those for urban and rural residents (p < 
      0.05), implying the continuous and greater exposure to these chemicals in the 
      e-waste recycling areas. BDE 209 (92-98%) was the major congener of PBDEs and CB 
      52 (26-51%) was the main congener of PCB in nail samples. However, no significant 
      gender difference was observed for PBDE and PCB levels in nails from all three 
      investigated areas, and no significant correlation was found between their levels 
      and the age of the participants. The enantiomer fractions (EFs) of CBs 95 and 132 
      indicated that the external sources (e.g. dust and/or air) were the primary 
      sources for CBs 95 and 132 in human nails from the e-waste area, while the 
      contribution from the internal sources (e.g. serum) could be in a small 
      percentage. The results of this study indicate that human nails can be used as a 
      proper indicator of human exposure to PCBs and PBDEs, and further studies are 
      needed by a comprehensive investigation of the relationships between the PCB and 
      PBDE levels in the nails and serum and/or other internal tissues.
