AB  - Biomagnification of persistent organic pollutants (POPs) in food webs has been 
      studied for many years. However, the different processes and influencing factors 
      in biomagnification of POPs in aquatic and terrestrial food webs still need 
      clarification. Polychlorinated biphenyls (PCBs) and short-chain chlorinated 
      paraffins (SCCPs) were measured in organisms from adjacent terrestrial and 
      aquatic environment in this study. The median levels of PCBs in terrestrial and 
      aquatic organisms were 21.7-138 ng/g lw and 37.1-149 ng/g lw, respectively. SCCP 
      concentrations were 18.6-87.3 mug/g lw and 21.4-93.9 mug/g lw in terrestrial and 
      aquatic organisms, respectively. Biomagnification factors (BMFs) of PCBs 
      increased with higher log K(OW) in all food chains. BMFs of SCCPs were negatively 
      correlated with log K(OW) in aquatic food chains, but positively correlated with 
      log K(OW) in terrestrial food chains. The terrestrial food web had similar 
      trophic magnification factors (TMFs) of PCBs, and higher TMFs of SCCPs than the 
      aquatic food web. Biomagnification of PCBs was consistent in aquatic and 
      terrestrial food webs, while SCCPs had higher biomagnification potential in 
      terrestrial than aquatic organisms. The distinct biomagnification of SCCPs was 
      affected by the respiratory elimination for terrestrial organisms, the different 
      metabolism rates in various species, and more homotherms in terrestrial food 
      webs. Fugacity model can well predict levels of less hydrophobic chemicals, and 
      warrants more precise toxicokinetic data of SCCPs.
