AB  - Bioaccumulation factor (BAF) of pollutants is an important parameter for 
      evaluating their bioaccumulation potential and an important indicator for 
      evaluating their environmental risks. However, little study exits on the BAF of 
      novel brominated flame retardants (NBFRs). The present study determined 17 NBFRs 
      in 24 water samples in dissolved phase and 93 crucian carp samples collected from 
      an electronic waste recycling site in northern China, in order to examine their 
      contamination, distribution and bioaccumulation. The results showed that the 
      targeted NBFRs were widely detectable in the dissolved phase and crucian carps. 
      In dissolved phase, allyl 2,4,6-tribromophenyl ether (ATE) had the highest 
      detectable rate (100%) and concentration (mean: 1.3 +/- 0.62 ng/L), but in crucian 
      carp, hexachlorocyclopentenyl-dibromocyclooctane (HCDBCO) was the one with the 
      highest detectable rate (89%) and concentration (mean: 16 +/- 9.2 ng/g wet weight 
      (ww)) among all 17 NBFRs. The discharge and water solubility of NBFRs determined 
      their concentration in the dissolved phase, while the concentration of NBFRs in 
      crucian carp was the results of their discharge and food exposure. The estimated 
      BAFs exceeded 5000 L/kg for petabromoethylbenzene (PBEB), pentabromotoluene 
      (PBT), HCDBCO, pentabromobenzyl acrylate (PBBA), 1,2,3,4,5-pentabromobenzene 
      (PBBZ), 2,3-dibromopropyl-2,4,6-tribromophenyl ether (DPTE), hexabromobenzene 
      (HBBZ), and alpha-1,2,5,6-tetrabromocyclooctane (alpha-TBCO), suggesting that these 
      compounds were above the hazard standard of bioaccumulation. Although the BAFs of 
      2,3,5,6-tetrabromo-p-xylene (p-TBX), 1,2-bis(2,4,6-tribromophenoxy)-ethane 
      (BTBPE), alpha-/beta-tetrabromoethylcyclohexane (alpha-/beta-TBECH) and ATE were less than 
      5000, the potential of bioaccumulation cannot be ignored. The log BAF of tested 
      NBFRs showed a pattern of first increasing and then decreasing with the increase 
      of log K(OW), the water solubility of NBFRs, the exposure to fish, the uptake and 
      depuration of fish were the key factor to this pattern. To our knowledge, the BAF 
      values of the most of NBFRs calculated in this study were not reported in the 
      published work previously.
