Where is it Commonly Found?
TCPP is widely used in sprayed-in building insulation and refrigerator casings (WHO 1998).TCPP has been used since the mid-1960s in rigid and flexible polyurethane foams, in thermoset and thermoplastic materials, and in textile finishes (OEHHA 2009).
TCPP is a suspected carcinogen (WHO 1998) and as of August 2011 is under study for genotoxicity and reproductive toxicity by the National Toxicology Program of the National Institute of Environmental Health Sciences. TCPP is structurally similar to three other halogenated flame retardants—TCEP, TDBPP and TDCPP--that have been identified as carcinogens (OEHHA 2009). TCEP and TDBPP are listed as known carcinogens under California Proposition 65.
TCPP and TCEP have been called “the most recalcitrant and ubiquitous in water and air” of organophosphate esters that have been studied (Reemtsma et al 2008). TCPP has been detected in household dust, though at lower levels than some other flame retardants (Stapleton et al 2009). TCPP showed “no significant removal” when passing through wastewater treatment plants (which “routinely” detect TCPP in effluents) in several European studies, thus downstream surface waters are also contaminated (Reemtsma et al 2008). PVC wallpaper treated with TCPP was found to emit TCPP into air (Ni et al 2007).
