      bioaccumulative: evidence from field determined bioaccumulation factors.

AB  - With the phaseout of brominated flame retardants (BFRs) polybrominated diphenyl 
      ethers (PBDEs), some non-PBDE BFRs have prompted to be alternatives to the 
      discontinued PBDEs. To assess the bioaccumulation potential of these chemicals, 
      field bioaccumulation factors (BAFs) for several non-PBDE BFRs including 
      hexabromocyclododecanes (HBCDs), 1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), 
      pentabromotoluene (PBT), pentabromoethylbenzene (PBEB), and hexabromobenzene 
      (HBB), were determined in the aquatic species from a natural pond in an 
      electronic waste recycling site in South China. The log BAFs ranged 2.58-6.01, 
      3.24-5.58, 3.44-5.98, 2.85-5.98, 3.32-6.08, 2.04-4.77, 2.72-4.09 and 3.31-5.54 
      for alpha-HBCD, beta-HBCD, gamma-HBCD,  summation operatorHBCDs, BTBPE, PBT, PBEB, and HBB, respectively. The 
      log BAF values for HBCD isomers, BTBPE, and HBB were greater than 3.7 
      (corresponding BAF value 5000) in most of the investigated species, demonstrating 
      their highly bioaccumulative properties. alpha-, beta-, and gamma-HBCDs, BTBPE, and HBB 
      appeared comparable or had even greater BAFs compared to PBDE congeners with 
      similar K(OW), suggesting that these BFRs may have a potentially high 
      environmental risk. The BAFs for the given BFR compound were largely variable 
      between species, due to the species-specific feeding ecology, trophic level, and 
      metabolic capacity for these pollutants. Positive linear relationships between 
      log BAF and log K(OW) (r(2) = 0.59, p = 0.04), and molecular weight (r(2) = 0.54, p = 
      0.06) of non-PBDE BFRs were observed in the species with low trophic level 
      (Chinese mysterysnail), suggesting that the chemical's physicochemical properties 
      also played key roles in the bioaccumulation processes.
