摘      要：Organophosphate flame retardants(OPFRs)are a group of semi-volatile organic compounds(SVOCs)and among the most abundant contaminants *** indoor presence has been associated with potential health risks however there is limited understanding as to how they are released from indoor *** study uses an emission micro-chamber to explore one of the currently understudied chemical migration pathways;direct transfer between a source material and settled dust in contact with the source.A tris(2-chloroisopropyl)phosphate(TCIPP)-treated insulation board is used as the source *** and substantial transfer was observed after only 8 h of source-dust contact,resulting in 80 times higher concentrations in dust compared to pre-experiment *** time points at 24 h and 7 d showed similarly high average dust levels and the TCIPP in the dust and air in the chamber was calculated to be close to thermodynamic *** was concluded that TCIPP was effectively transferred from the insulation board to the dust on its surface and the surrounding air via gas-phase *** a real room,a gradient of TCIPP concentrations in air above the surface of a product could result in higher concentrations in dust sitting on the product than dust in the rest of the room.
