Distribution of Organophosphate Esters between the Gas and Particle Phase-Model Predictions vs Measured Data
Original language description
Gas-particle partitioning is one of the key factors that affect the environmental fate of semivolatile organic chemicals. Many organophosphate esters (OPEs) have been reported to primarily partition to particles in the atmosphere. However, because of the wide range of their physicochemical properties, it is unlikely that OPEs are mainly in the particle phase "as a class". We compared gas-particle partitioning predictions for 32 OPEs made by the commonly used OECD Pov and LRTP Screening Tool ("the Tool") with the partitioning models of Junge-Pankow (J-P) and Hamer-Bidleman (H-B), as well as recently measured data on OPE gas-particle partitioning. The results indicate that half of the tested OPEs partition into the gas phase. Partitioning into the gas phase seems to be determined by an octanol-air partition coefficient (log K-OA) < 10 and a subcooled liquid vapor pressure (log P-L) > -5 (P-L in Pa), as well as the total suspended particle concentration (TSP) in the sampling area.
