The Report on Carcinogens (RoC) is an informational scienti.c and public health document that identifies and discusses agents, substances, mixtures, or exposure circumstances (hereinafter referred to as substances) that may pose a hazard to human health by virtue of their carcinogenicity. For each listed substance, the RoC contains a substance profile which provides information on (1) the listing status, (2) cancer studies in humans and animals, (3) studies of genotoxicity (ability to damage genes) and biologic mechanisms, (4) the potential for human exposure to these substances, and (5) Federal regulations to limit exposures. The RoC does not present quantitative assessments of the risks of cancer associated with these substances. Thus, the listing of substances in the RoC only indicates a potential hazard and does not establish the exposure conditions that would pose cancer risks to individuals in their daily lives.
