N2 - Organophosphate flame retardants (OPFRs) have been increasingly consumed as alternative of PBDEs for their retardant and plastic properties. OPFRs are additives rather than chemical bonded to the products, allowing their release into the indoor and outdoor environments via volatilization, abrasion, and dissolution, which may lead to adverse health effects. The study is aimed to realize the profiles of OPFRs via different exposure routes and estimate the daily exposure doses for adults and children. The indoor and outdoor air, house dust and skin wipe samples were collected from 60 households and their residents. 11 OPFRs in indoor and outdoor air, house dust, skin wipe samples were analysed using GC-EI/MS. TBOEP and TCIPP were the dominant compounds in the paired skin wipe, house dust, indoor/outdoor air. Exposure dose of OPFRs for adults and children was mainly contributed from dermal absorption and inhalation of indoor air. The exposure risks of non-carcinogenic and carcinogenic effects would be acceptable.
