Organophosphorus FR metabolites detected in urban air

Organophosphorus FR metabolites detected in urban air across the world. Metabolites of five OPFR (organophosphate ester flame retardants) TCEP, TCPP, TDCPP (chlorinated) and TBEP, TPhP (non-chlorinated) were analysed in samples of air from 18 megacities worldwide (Global Atmospheric Passive Sampling – Megacities programme). Nineteen metabolites were detected, of which ten metabolites (6 chlorinated, 4 non-chlorinated) were identified to specific molecules. Total concentrations were in all cases < 0.005 µg/m3. The authors suggest that the results show the need to consider atmospheric transformations when assessing chemical risks.
