      Workers in Southern China: Concentrations, Chiral Signatures, Correlations, and 
      Source Identification.

AB  - Hair is increasingly used as a biomarker for human exposure to persistent organic 
      pollutants (POPs). However, the internal and external sources of hair POPs remain 
      a controversial issue. This study analyzed polychlorinated biphenyls (PCBs) in 
      human hair and serum from electronic waste recycling workers. The median 
      concentrations were 894 ng/g and 2868 ng/g lipid in hair and serum, respectively. 
      The PCB concentrations in male and female serum were similar, while 
      concentrations in male hair were significantly lower than in female hair. 
      Significant correlations between the hair and serum PCB levels and congener 
      profiles suggest that air is the predominant PCB source in hair and that hair and 
      blood PCB levels are largely dependent on recent accumulation. The PCB95, 132, 
      and 183 chiral signatures in serum were significantly nonracemic, with mean 
      enantiomer fractions (EFs) of 0.440-0.693. Nevertheless, the hair EFs were 
      essentially racemic (mean EFs = 0.495-0.503). Source apportionment using the 
      Chemical Mass Balance model also indicated primary external PCB sources in human 
      hair from the study area. Air, blood, and indoor dust are responsible for, on 
      average, 64.2%, 27.2%, and 8.79% of the hair PCBs, respectively. This study 
      evidenced that hair is a reliable matrix for monitoring human POP exposure.
