In the present study, we investigated the presence of PBDEs and alternative FRs such as emerging halogenated FRs (EHFRs) and organophosphate flame retardants (PFRs) in indoor dust samples from British and Norwegian houses as well as British stores and offices. BDE209 was the most abundant PBDE congener with median concentrations of 4,700 ng g-1 and 3,400 ng g-1 in UK occupational and house dust, respectively, 30 and 20 fold higher than in Norwegian house dust. Monomeric PFRs (m-PFRs), including triphenyl phosphate (TPHP), tris(chloropropyl) phosphate (TCPP) and tris(2-chloroethyl) phosphate (TCEP) dominated all the studied environments. To the best of our knowledge, this is the first report of isodecyldiphenyl phosphate (iDPP) and trixylenyl phosphate (TXP) in indoor environments. iDPP was the most abundant oligomeric PFR (o-PFR) in all dust samples, with median concentrations one order of magnitude higher than TXP and bisphenol A bis(diphenyl phosphate (BDP). iDPP and TXP worst-case scenario exposures for British workers during an 8h exposure in the occupational environment were equal to 34 and 1.4 ng kg bw-1 day-1, respectively. The worst-case scenario for BDE209 estimated exposure for British toddlers (820 ng kg bw-1 day-1) did not exceeded the proposed reference dose (RfD) (7,000 ng kg bw-1 day-1), while exposures for sum of m-PFRs (Σm-PFRs) in British toddlers and adults (17,900 and 785 ng kg bw-1 day-1 respectively) were an order of magnitude higher than for Norwegian toddlers and adults (1,600 and 70 ng kg bw-1 day-1).
