Agency Considers Agents for Listing as Known or Likely Human Carcinogens

RESEARCH TRIANGLE PARK, North Carolina—Sixteen chemicals and other agents will undergo toxicologic review by the National Toxicology Program for possible listing as known or reasonably anticipated to be human carcinogens in the 11th edition of the federal Report on Carcinogens.

The agency plans to review three viruses (hepatitis B, hepatitis C, and high-risk human papillomaviruses), three types of radiation (x-rays, gamma radiation, and neutrons), two substances formed in cooking, and nine chemicals to which certain industrial workers are exposed.
