AB  - Many novel brominated flame retardants (NBFRs) are used as substitutes of 
      polybrominated diphenyl ethers (PBDEs) in recent years. However, little is known 
      about their phototransformation behavior, which may influence the environmental 
      fate of these chemicals. In this study, photochemical behavior of five NBFRs, 
      allyl-2,4,6-tribromophenyl ether (ATE), 2-bromoallyl-2,4,6-tribromophenyl ether 
      (BATE), 2,3-dibromopropyl-2,4,6-tribromophenyl ether (DPTE), 
      1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), and 
      2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine (TTBP-TAZ) was investigated. 
      Results show all the five NBFRs can undergo photochemical transformation under 
      simulated sunlight irradiation. Quantum yields (Phi) of the five NBFRs varied from 
      0.012 of TTBP-TAZ in hexane to 0.091 of BTBPE in methanol. Half-lives (t1/2) 
      relevant with solar irradiation of these NBFRs were estimated using the 
      determined Phi, and the values are 1.5-12.0 d in summer and 17.1-165.0 d in winter. 
      Debrominated and ether bond cleavage products were identified in the 
      phototransformation of DPTE and BTBPE. Debromination on the phenyl is a main 
      phototransformation pathway for DPTE, and both debromination and ether bond 
      cleavage are main phototransformation pathways for BTBPE. This study is helpful 
      to better understand the phototransformation behavior of the NBFRs.
