AB  - To understand human exposure to dust-associated flame retardants in the biggest 
      metropolitan area (city of Shanghai) of East China, our study determined a suite 
      of legacy and emerging flame retardants in dust from dwellings, cars, and 
      university computer labs. The results exhibited a consistent dominance of 
      organophosphate flame retardants (OPFRs) over polybrominated diphenyl ethers 
      (PBDEs) and other alternative flame retardants (AFRs) regardless of 
      microenvironments. In addition to OPFRs, some alternative flame retardants, such 
      as decabromodiphenyl ethane (DBDPE), 2-ethylhexyltetrabromobenzoate (EH-TBB), 
      bis(2-ethylhexyl)-3,4,5,6-tetrabromobenzoate (BEH-TEBP), and 
      1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), were also frequently detected. 
      Among them, DBDPE exhibited concentrations comparable to those of PBDEs. 
      Comparison with international studies indicated that concentrations of  summation operatorPBDEs 
      (0.2-12.3 mug/g dry weight or dw) and  summation operatorOPFRs (3.8-165.5 mug/g dw) from Shanghai 
      dwellings (bedroom and living room) were generally in the middle of concentration 
      ranges reported worldwide, whereas elevated DBDPE concentrations (0.1-9.5 mug/g 
      dw) was observed compared with most other countries or regions. OPFR compositions 
      in house dust from this study also differed from those from many other countries. 
      This suggested inter-regional differences in market demands on the quantities and 
      types of flame retardants. Human intake estimation suggested elevated exposure 
      for toddlers when compared with adults, although the daily intake estimations of 
      individual flame retardants were generally 2-4 orders of magnitude lower than the 
      reference doses. The findings from this preliminary study developed a baseline 
      for future evaluation of the sources and fate of emerging flame retardants and 
      related human exposure risks in East China.
