AB  - This study investigated the quantitative sources of persistent organic pollutants 
      (POPs), their biomagnification factors, and their effect on POP biomagnification 
      in a typical waterbird (common kingfisher, Alcedo atthis) food web in South 
      China. The median concentrations of polychlorinated biphenyls (PCBs) and 
      polybrominated diphenyl ethers (PBDEs) in kingfishers were 32,500 ng/g lw and 
      130 ng/g lw, respectively. The congener profiles of PBDEs and PCBs showed 
      significant temporal changes because of the restriction time points and 
      biomagnification potential of different contaminants. The concentrations of most 
      bioaccumulative POPs, such as CBs 138 and 180 and BDEs 153 and 154, decreased at 
      lower rates than those of other POPs. Pelagic fish (metzia lineata) and benthic 
      fish (common carp) were the primary prey of kingfishers, as indicated by 
      quantitative fatty acid signature analysis (QFASA) results. Pelagic and benthic 
      prey species were the primary sources of low and high hydrophobic contaminants 
      for kingfishers, respectively. Biomagnification factors (BMFs) and trophic 
      magnification factors (TMFs) had parabolic relationships with log K(OW), with 
      peak values of approximately 7. Significant negative correlations were found 
      between the whole-body elimination rates of POPs in waterbirds and the 
      log-transformed TMFs and BMFs, indicating that the strong metabolism of 
      waterbirds could potentially affect POP biomagnification.
