Particle size distribution of PBDEs and NBFRs studied. Concentrations of most target BFRs in ESD exceed significantly those in FD. Concentrations of more volatile BFRs higher in finer particle size fractions. Concentrations of less volatile BFRs do not vary significantly with particle size. a r t i c l e i n f o a b s t r a c t Article history: This study investigates the particle size distribution of eight polybrominated diphenyl ethers (PBDEs) Received 25 March 2016 and five “novel” brominated flame retardants (NBFRs) in settled house dust. Elevated surface dust (ESD) Received in revised form and floor dust (FD) were collected from 5 homes in Birmingham, UK, yielding a total of 10 samples. Each 11 May 2016 sample was fractionated into three different particle sizes: 125e250 mm (P1), 63e125 mm (P2) and 25 Accepted 12 May 2016 e63 mm (P3). Non-fractionated bulk dust samples (BD) were also anal
