Children spend a considerable part of their day in preschool, where they may be exposed to hazardous chemicals indoor dust. In this study, brominated flame retardants (BFRs) and organophosphate esters (OPEs) were analyzed preschool dust (n = 100) children's hand wipe samples 100), diphenyl phosphate (DPHP) was urine 113). Here we assessed exposure via dust, identified predictors for studied correlations between different measures. The most abundant BFRs decabromodiphenyl ether (BDE-209) ethane (DBDPE) found at median levels 270 110 ng/g respectively. Tris(2-butoxyethyl) (TBOEP) the OPE, level 79 000 For all OPEs some BFRs, there significant wipes. addition, triphenyl (TPHP) significantly correlated with corresponding metabolite DPHP urine. pentaBDEs higher older preschools compared newer, whereas DBDPE newer preschools. Children's estimated intakes individual below available health-based reference values. However, are uncertainties about potential health effects emerging OPEs.
