This has raised concerns because indoor dust has been identified as one of the major non-dietary exposure pathways for children. In this study, 26 BFRs and OPEs were measured in indoor dust samples collected from 26 preschools in Sweden to identify potential indoor contamination sources and estimate the exposure risk of the detected levels.
