IARC: chlorinated FR TCPP carcinogenic
TCPP (tris(chloropropyl) phosphate), a halogenated FR, has been classed probably carcinogenic to humans (Group 2A) by IARC (International Agency for Research on Cancer), on the basis of sufficient evidence for cancer in animal tests and strong mechanistic evidence in primary human cells. A summary of the IARC findings has been published and the full report will be published in ‘IARC Monographs on the Identification of Carcinogenic Hazards to Humans’.
