AB  - A clean-up method was developed to enable the determination of tri-decabrominated 
      diphenyl ethers, isomer-specific hexabromocyclododecanes (HBCDs), 
      1,2-bis(2,4,6-tribromophenoxy)ethane (BTBPE), decabromodiphenyl ethane (DBDPE), 
      (2-ethylhexyl)tetrabromobenzoate (TBB), and bis(2-ethylhexyl)tetrabromophthalate 
      (TBPH) in the same dust sample extract using reasonable amounts of solvents and 
      without dividing the sample. After extraction, the sample was separated on a 
      silica column into three fractions that were subsequently cleaned up 
      individually. The polybrominated diphenyl ethers (PBDEs) and DBDPE were eluted in 
      Fraction I, TBB, TBPH, and BTBPE in Fraction II, and HBCDs in Fraction III. 
      Fractions I and II were analyzed using gas chromatography/mass spectrometry and 
      Fraction III using liquid chromatography/mass spectrometry. The method gave good 
      recoveries (60-120%), precise results using (13) C-labelled internal standards 
      and was accurate when comparing results to certified values (PBDEs in NIST SRM 
      2585). The method was applied to dust samples from the Stockholm (Sweden) area. 
      All the emerging brominated flame retardants (BFRs) studied, except BTBPE, were 
      present in all the samples in quantifiable concentrations, often higher than the 
      PBDEs. BTBPE was quantified in only one sample. It is evident that emerging BFRs 
      are present in Swedish homes, and these compounds should be included in the BFR 
      analyses of indoor environments.
