NTP 11th Report on Carcinogens

Rep Carcinog. 2004;11:1-A32.


The Report on Carcinogens (RoC) is a scientific and public health document mandated by Congress in 1978. The RoC identifies and discusses substances, chemicals, mixtures, or exposure circumstances (collectively called substances) that may pose a cancer hazard to human health and to which persons in the United States are exposed. Nominations to the RoC go through a rigorous review process with multiple opportunities for public comment. The RoC is a compilation of substance profiles and each new edition replaces the previous one. Each substance profile in the RoC identifies a substance as known or reasonably anticipated to be a human carcinogen and provides information on (1) the scientific evidence that supports the listing (human epidemiological studies, cancer studies in experimental animals, and toxicokinetic, genotoxic, and mechanistic data), (2) the potential for human exposure, such as data on use, production, environmental occurrence, occupational exposure, and exposure to the general population, and (3) current Federal regulations to limit exposure.
