Phosphorous flame-retardant concentration in Finnish daycares dust and children's exposure.

Children in daycare centers are exposed to various chemicals present in indoor dust, including organophosphorus flame retardants (OPFRs). This study analyzed OPFR levels in dust from 18 daycare centers in Tampere, Finland, to assess children's exposure through dust ingestion, inhalation, and dermal absorption. The OPFRs measured included tris(2-chloroisopropyl) phosphate (TCIPP), tris(1,3-dichloro-2-propyl) phosphate (TDCIPP), triphenyl phosphate (TPHP), and 2-ethylhexyl diphenyl phosphate (EHDPP).
