AB  - As a class of alternative flame retardants, "novel" brominated flame retardants 
      (NBFRs) have been widely used in clothing, textiles, electronics, building 
      materials, and plastics and are frequently found in environmental samples. 
      Although the use and discharge of NBFRs are increasing all over the world, little 
      information is available about their fates and removal in wastewater treatment 
      plants (WWTPs). This study investigated the occurrence and behavior of 
      2,4,6-tribromophenyl allyl ether (ATE), 2,3-dibromopropyl tribromophenyl ether 
      (DPTE), 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) in a municipal WWTP in Beijing, China. Four of the NBFRs (ATE, 
      BTBPE, TBPH, and DBDPE) were detected in all wastewater and biosolid samples. The 
      dominant compound in both wastewater and biosolid samples was DBDPE, with 
      concentrations in the ranges of 6.4-18 ng/L and 83-288 ng/g dry weight (dw), 
      respectively. A mass flow analysis indicated that the overall removal 
      efficiencies were 31+/-18% for ATE, 97+/-1.5% for DPTE, 79+/-11% for BTBPE, 87+/-5.3% for 
      TBPH, and 93+/-3.3% for DBDPE, but the removal efficiency in aqueous phase only 
      ranged from -43 (ATE) to 57% (DBDPE). The low and negative removal efficiencies 
      of ATE were possibly due to the transformation of DPTE during the anaerobic 
      treatment processes. Under the aerobic conditions, BTBPE, TBPH and DBDPE 
      underwent a very slow biodegradation. A total of 68-91% of the initial mass 
      loadings of ATE, BTBPE, TBPH and DBDPE were found in the biosolid samples, 
      suggesting that the four NBFRs were removed mainly via sorption in the WWTP.The 
      biosolid was a huge reservoir of target NBFRs, and effective removal of NBFRs 
      during treatment in the WWTP is critical.
