AB  - Alternative brominated flame-retardants (BFRs), 2-ethylhexyl 
      2,3,4,5-tetrabromobenzoate (TBB), 2-ethylhexyl 2,3,4,5-tetrabromophthalate 
      (TBPH), 1,2-bis(2,4,6-tribromophenoxy) ethane (BTBPE) and decabromodiphenyl 
      ethane (DBDPE), are now being detected in the environment. However, contaminant 
      bioavailability is influenced by the organisms' ecology (i.e., route of uptake) 
      and in situ environmental factors. We observed that the filter-feeding bivalve 
      (Corbicula fluminea) and grazing gastropod (Elimia proxima), collected downstream 
      from a textile manufacturing outfall, exhibited TBB, TBPH, and BTBPE 
      concentrations from 152 to 2230 ng g(-1) lipid weight (lw). These species also 
      contained additional BFRs. Maximum levels of total hexabromocyclododecane 
      diastereomers ( summation operatorHBCDs) in these species were 363,000 and 151,000 ng g(-1) lw, and 
      those of polybrominated diphenyl ethers ( summation operatorPBDEs) were 64,900 and 47,200 ng g(-1) 
      lw, respectively. These concentrations are among the highest reported to date 
      worldwide. While BDE-209 was once thought to be nonbioavailable and resistant to 
      degradation, it was the dominant BFR present and likely debromination products 
      were detected. Contributions of alpha- and beta-HBCD were higher in tissues than 
      sediments, consistent with gamma-HBCD bioisomerization. Mollusk bioaccumulation 
      factors were similar between HBCD and PBDEs with 4 to 6 bromines, but factors for 
      TBB, TBPH, and BTBPE were lower. Despite different feeding strategies, the 
      bivalves and gastropods exhibited similar BFR water and sediment accumulation 
      factors.
