Kinetic analysis of Tris(chloropropyl)phosphate (TCPP) emission from fireproofed upholstered furniture under realistic indoor conditions
Résumé
This study deals with the emission kinetic of TCPP from a source material under realistic in-door conditions. The analysis is based on the results of a measurement campaign carried out over a period of almost one year in two rooms after introduction of fireproofed upholstered furniture where the gaseous concentration at the material surface (y°) and airborne concentra-tion (Ca) were regularly measured. Basing on data, the emission rate was estimated at 8 μg.m-2.h-1 on average with no decline trend observed after about one year’s emission. The released mass of TCPP over one year represented about 0.2% of the initial content of TCPP in the ma-terial. A model was developed to provide predictions on the long-term trend in TCPP emis-sion from the source material. The simulations showed that the TCPP emission persists over long periods of time (several years) with the same intensity level under indoor conditions
