TI  - Polybrominated Diphenyl Ethers (PBDEs) in paired human hair and serum from 
      e-waste recycling workers: source apportionment of hair PBDEs and relationship 
      between hair and serum.

AB  - Human hair has been widely used as a bioindicator for human persistent organic 
      pollutants (POPs) exposure, but studies on the sources of hair POPs and the 
      relationship between hair and body burden are limited. This study analyzed the 
      possible source apportionment of hair PBDEs and examined the relationship between 
      PBDE concentrations in paired hair and serum from e-waste recycling workers. 
      Using the ratio of BDE 99/47 and BDE 209/207 as indices, we calculated that only 
      15% of the highly brominated congeners (nona- and deca-BDE congeners) comes from 
      exogenous (external) exposure for both female and male hair, but an average of 
      64% and 55% of the lower-brominated congeners (tetra- to penta-BDE congeners) 
      come from exogenous exposure for female and male hair, respectively. The higher 
      contribution of exogenous exposure for less-brominated congeners could be related 
      to their relatively lower log KOW and higher volatility than higher-brominated 
      congeners, which make them more readily to evaporate from dust and then to be 
      adsorbed on hair. Higher hair PBDE levels and higher exogenous exposure of 
      less-brominated congeners in females than in males can be attributed to a longer 
      exogenous exposure time for females than males. Significant positive 
      relationships were found in tri- to hepta-BDE congeners (BDE 28, 47, 66, 85, 100, 
      153, 154, and 183) (R = 0.36-0.55, p < 0.05) between hair and serum, but this 
      relationship was not found for octa- to deca-BDE. Difference in the half-lives 
      between highly brominated congeners and less-brominated congeners could be a 
      reason. This result also implied that we should treat the results of correlation 
      analyses between hair and other organs cautiously.
