Tris(1-chloro-2-propyl)phosphate (TCPP) is an additive flame retardant. It is used extensively in rigid and flexible polyurethane foam. TCPP is also used in thermoset and thermoplastic materials and in textile finishes. Annual . production/import volume was 10-50 million pounds for the reporting years 1990, 1994, 1998 and 2002 (. EPA, 2002). An increased use of TCPP in Europe has been linked to a decreased use of tris(2-chloroethyl)phosphate (TCEP). Studies in Sweden found high levels of TCPP in indoor environments (Marklund et al., 2005). Particularly high concentrations were found in the interiors of automobiles, buses and subway.
