DEPARTMENT OF HEALTH AND HUMAN SERVICES
PUBLIC HEALTH SERVICE
The National Toxicology Program (NTP) Announces the Availability of the Report on Carcinogens, Eleventh Edition.
The Department of Health and Human Services released the Report on Carcinogens, Eleventh Edition to the public on January 31, 2005. The report is available free-of-charge on the Internet from the NTP website at: http://ntp.niehs.nih.gov. Printed copies of the Report on Carcinogens, Eleventh Edition can be obtained by contacting: Central Data Management (CDM), MD-EC-03, National Institute of Environmental Health Sciences, P.O. Box 12233, 79 T.W. Alexander Dr., Building 4401, Suite 100, Research Triangle Park, NC 27709 USA; 919-541-3419 (phone), 919-541-3687 (fax), email: cdm@niehs.nih.gov.
Background
The Report on Carcinogens (RoC) (previously known as the Annual Report on Carcinogens) is a Congressionally mandated listing of known human carcinogens and reasonably anticipated human carcinogens whose preparation is delegated to the NTP by the Secretary, Department of Health and Human Services (DHHS). Section 301(b)(4) of the Public Health Service Act, as amended, provides that the Secretary, DHHS, shall publish a biennial report which contains a list of all substances (1) which either are known to be human carcinogens or may reasonably be anticipated to be human carcinogens; and (2) to which a significant number of persons residing in the United States are exposed. The law also states that the reports should provide available information on the nature of exposures, the estimated number of persons exposed, and the extent to which the implementation of federal regulations decreases the risk to public health from exposure to these chemicals.
The RoC is an informational, scientific, and public health document that identifies and discusses agents, substances, mixtures, or exposure circumstances that may pose a carcinogenic hazard to human health. It serves as a meaningful and useful compilation of data on the (1) carcinogenicity, genotoxicity, and biologic mechanisms of the listed substances in humans and/or animals, (2) the potential for exposure to these substances, and (3) the regulations promulgated by Federal agencies to limit exposures. The report does not present quantitative assessments of carcinogenic risk, an assessment that defines the conditions under which the hazard may be unacceptable. Listing of substances in the report, therefore, does not establish that such substances present carcinogenic risks to individuals in their daily lives. Such formal risk assessments are the purview of the appropriate federal, state, and local health regulatory and research agencies.
New Listings to the RoC, Eleventh Edition
The RoC, Eleventh Edition, contains 246 entries, 17 of which have not appeared in earlier RoCs. The table below summarizes the actions taken for the substances or exposure circumstances reviewed for possible listing in the RoC, Eleventh Edition.
The review of the new entries to the RoC, Eleventh Edition followed a formal process that included many phases of scientific peer review and multiple opportunities for public comment. The process included three scientific peer reviews: two separate, internal reviews conducted by scientists within the federal government and an external review in a public forum conducted by both non-government and government scientists. The three scientific review committees evaluated all available data relevant to the criteria for inclusion of candidate nominations in the report. The criteria used to evaluate the nominations and a description of the review procedures used are available on the NTP website at http://ntp.niehs.nih.gov/ or by contacting: Dr. C. W. Jameson, Head - Report on Carcinogens, National Toxicology Program, National Institute of Environmental Health Sciences, MD EC-14, P.O. Box 12233, Research Triangle Park, NC 27709; phone: (919) 541-4096, fax: (919) 541-0144, email: jameson@niehs.nih.gov.
Questions or comments concerning the RoC, Eleventh Edition should be directed to: Dr. Mary Wolfe, NTP Liaison and Scientific Review Office, National Institute of Environmental Health Sciences, MD-A3, P.O.

Summary of Actions for
Agents, Substances, Mixtures or Exposure Circumstances
Reviewed for Listing in the
Eleventh Edition of the Report on Carcinogens
| NOMINATIONS | PRIMARY USES OR EXPOSURES | ACTION |
|---|---|---|
| 1-Amino-2,4-dibromoanthraquinone | An anthraquinone-derived vat dye that is used in the textile industry. | Listed as reasonably anticipated to be a human carcinogen |
| Cobalt Sulfate | Used in electroplating and electrochemical industries. It is also used as a coloring agent for ceramics and as a drying agent in inks, paints, varnishes and linoleum, and has been added to animal feed as a mineral supplement. | Listed as reasonably anticipated to be a human carcinogen |
| Diazoaminobenzene | Used as an intermediate in the production of dyes and to promote adhesion of natural rubber to steel. | Listed as reasonably anticipated to be a human carcinogen |
| Diethanolamine | Used in the preparation of surfactants used in liquid laundry, dishwashing detergents, cosmetics, shampoos, and hair conditioners; as a surface-active agent and corrosion inhibitor in metalworking fluids; and as a dispersant in agricultural chemical formulations. | Not Listed |
| Hepatitis B Virus | A small DNA-enveloped virus that, along with Hepatitis C Virus, causes most parenterally transmitted viral hepatitis. | Listed as known to be a human carcinogen |
| Hepatitis C Virus | An RNA-enveloped virus that, along with Hepatitis B Virus, causes most parenterally transmitted viral hepatitis. | Listed as known to be a human carcinogen |
| Selected Heterocyclic Amines (three): 1) 2-Amino-3,4-dimethylimidazo[4,5-f]quinoline (MeIQ) 2) 2-Amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx) 3) 2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) |
Listed as reasonably anticipated to be a human carcinogen | |
| Human Papillomaviruses, Some Genital-Mucosal Types | Small, non-enveloped viruses that infect genital skin, and genital and non-genital mucosa. HPV infections are common throughout the world. | Listed as known to be a human carcinogen |
| Lead and Lead Compounds | Major use is in making lead-acid storage batteries. Other common uses include ammunition and cable covering. Lead compounds are used in paint, glass, ceramics, fuel additives, and some traditional cosmetics. | Listed as reasonably anticipated to be a human carcinogen |
| Naphthalene | Used as an intermediate in the synthesis of many industrial chemicals, and has been used as an ingredient in some moth repellants and toilet bowl deodorants. | Listed as reasonably anticipated to be a human carcinogen |
| Neutrons | Exposures normally occur from a mixed irradiation field in which neutrons are a minor component. The exceptions are exposure of patients to neutron radiotherapy beams and exposures of aircraft passengers and crew. | Listed as known to be a human carcinogen |
| Nitrobenzene | Used mainly in the production of aniline, itself a major chemical intermediate in the production of dyes. | Listed as reasonably anticipated to be a human carcinogen |
| Nitromethane | Used in specialized fuels, in explosives, and in the synthesis of nitromethane derivatives, pharmaceuticals, agricultural soil fumigants, and industrial antimicrobials | Listed as reasonably anticipated to be a human carcinogen |
| 4,4'-Thiodianiline | Used as an intermediate of several diazo dyes. | Listed as reasonably anticipated to be a human carcinogen |
