AB  - Despite the increasing use and discharge of novel brominated flame retardants, 
      little information is available about their trophodynamics in the aquatic food 
      web, and their subsequent relationships to compound metabolism. In this study, 
      concentrations of 2,4,6-tribromophenyl allyl ether (ATE), 
      1,2-dibromo-4-(1,2-dibromoethyl)cyclohexane (TBECH), tetrabromo- o-chlorotoluene 
      (TBCT), pentabromobenzyl acrylate (PBBA), 1,2-bis(2,4,6-tribromophenoxy)ethane 
      (BTBPE), bis(2-ethylhexyl)-3,4,5,6-tetrabromo-phthalate (TBPH), and 
      decabromodiphenyl ethane (DBDPE) were measured in 17 species, including plankton, 
      invertebrates, and fish from Lake Taihu, South China. Trophodynamics of the 
      compounds were assessed, and metabolic rates were measured in the liver 
      microsomes of crucian (trophic level [TL]: 2.93), catfish (TL: 3.86), and 
      yellow-head catfish (TL: 4.3). Significantly positive relationships were found 
      between trophic levels and lipid-normalized concentrations of ATE, BTBPE, and 
      TBPH; their trophic magnification factors (TMFs) were 2.85, 2.83, and 2.42, 
      respectively. Consistently, the three chemicals were resistant to metabolism in 
      all fish microsomes. No significant relationship was observed for betaTBECH ( p = 
      0.116), and DBDPE underwent trophic dilution in the food web (TMFs = 0.37, p = 
      0.021). Moreover, these two chemicals showed steady metabolism with incubation 
      time in all fish microsomes. TBCT and PBBA exhibited significant trophic 
      magnifications in the food web (TMF = 4.56, 2.01). Though different metabolic 
      rates were observed for the two compounds among the tested fish species, TBCT and 
      PBBA both showed metabolic resistance in high-trophic-level fish. These results 
      indicated that metabolism of organisms at high trophic levels plays an important 
      role in the assessment of trophic magnification potentials of these flame 
      retardant chemicals.
