U.S. may name styrene monomer as a carcinogen

ERJ staff report (DS)

Washington DC -- The U.S. National Toxicology Programme has placed styrene monomer on its candidate list as being a possible carcinogen. The Programe has published the list of candidate substances for the 12th Report on Carcinogens (RoC), and styrene appears in the list on the basis of an allegation by one individual, based on an IARC finding of limited evidence of carcinogenicity in animals and limited evidence of carcinogenicity in humans.

Substances on the candidate list will now go for review which has two important stages: (1) the public peer review of draft background documents by ad hoc scientific expert panels and (2) the public peer review of draft substance profiles for candidate substances by the NTP Board of Scientific Counselors.The NTP will, on a trial basis, prepare a response to public comments for the 12th RoC.

The organisation now invites public comment.
