Abstract Human exposure to brominated flame retardants (BFRs) such as hexabromocyclododecane (HBCD) mainly occurs through diet and dust ingestion. In this study, the HBCD concentrations in 124 vacuum dust samples of six indoor environments (homes, offices, kindergartens, cars, schools, and public indoor environments) and 32 surface dust samples were investigated. The median HBCD concentrations ranged from 106.30 ng g-1 in home dust to 496.13 ng g-1 in office dust. The estimated daily intakes (EDI) of HBCD (dust+diet) for toddlers were 6.18 ng kg-1 bw d-1. In general, the ΣHBCD estimated body burden of Korean adults showed good agreement with the reported HBCD median concentrations in their sera. Since the developmental health effect of exposure to HBCD was categorized as “high hazard” by the US Environmental Protection Agency, the estimated high body burden of ΣHBCD in Korean toddlers (9.76 ng g-1 lw) warns us of possible adverse effects on the development of essential systems in their bodies.
