Just Accepted “Just Accepted” manuscripts have been peer-reviewed and accepted for publication. They are posted online prior to technical editing, formatting for publication and author proofing. The American Chemical Society provides “Just Accepted” as a free service to the research community to expedite the dissemination of scientific material as soon as possible after acceptance. “Just Accepted” manuscripts appear in full in PDF format accompanied by an HTML abstract. “Just Accepted” manuscripts have been fully peer reviewed, but should not be considered the official version of record. They are accessible to all readers and citable by the Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered to authors. Therefore, the “Just Accepted” Web site may not include all articles that will be published in the journal. After a manuscript is technically edited and formatted, it will be removed from the “Just Accepted” Web site and published as an ASAP article.

Abstract

17

Concentrations of 27 emerging (EFRs) and legacy flame retardants (LFRs) were measured in

18

samples of indoor air (n=35) and indoor dust (n=77) from UK homes and offices. All target

19

compounds were detected in indoor air and dust samples. Relatively volatile EFRs (e.g.

20

tetrabromoethylcyclohexane – DBE-DBCH) were more frequently detected in indoor air

21

(detection frequencies > 60%), while less volatile EFRs (e.g. tetrabromobisphenolA-bis(2,3-

22

dibromopropyl ether (TBBPA-BDBPE) and decabromodiphenyl ethane (DBDPE)) were

23

predominant in dust. Concentrations of some EFRs (e.g. DBDPE) exceeded significantly those

24

reported previously in UK dust (p
