New Substances Added to HHS Report on Carcinogens
On June 10, 2011, the U.S. Department of Health and Human Services added eight substances to its Report on Carcinogens, a science-based document that identifies chemicals and biological agents that may put people at increased risk for cancer.
The industrial chemical formaldehyde and a botanical known as aristolochic acids are listed as known human carcinogens. Six other substances - captafol, cobalt-tungsten carbide (in powder or hard metal form), certain inhalable glass wool fibers, o-nitrotoluene, riddelliine, and styrene - are added as substances that are reasonably anticipated to be human carcinogens. With these additions, the 12th Report on Carcinogens now includes 240 listings.
The Report on Carcinogens is a congressionally mandated document that is prepared for the HHS Secretary by the National Toxicology Program. The report identifies agents, substances, mixtures, or exposures in two categories: known to be a human carcinogen and reasonably anticipated to be a human carcinogen.
