SUPPLEMENTARY INFORMATION: 

Background Information on the RoC

    The RoC is a congressionally mandated document that identifies and 
discusses agents, substances, mixtures, or exposure circumstances 
(collectively referred to as ``substances'') that may pose a hazard to 
human health by virtue of their carcinogenicity. Substances are listed 
in the report as either known or reasonably anticipated to be human 
carcinogens. The listing of a substance in the RoC indicates a 
potential hazard, but does not establish the exposure conditions that 
pose a cancer hazard to individuals in their daily lives. For each 
listed substance, the RoC provides information from cancer studies that 
support the listing as well as information about potential sources of 
exposure and current federal regulations to limit exposures. Each 
edition of the RoC is cumulative, that is, it lists newly reviewed 
substances in addition to substances listed in the previous edition. 
Information about the RoC is available on the RoC Web site (http://ntp.niehs.nih.gov/go/roc13) or by contacting Dr. Lunn (see ADDRESSES 
above).
    The NTP prepares the RoC on behalf of the Secretary of Health and 
Human Services. For the 13th RoC, the NTP followed an established, 
multi-step process with multiple opportunities for public input, and 
used established criteria to evaluate the scientific evidence on each 
candidate substance under review (http://ntp.niehs.nih.gov/go/rocprocess).

New Listings to the 13th RoC

    The 13th RoC contains 243 listings, some of which consist of a 
class of structurally related chemicals or agents. There are three new 
listings and one revised listing in this edition. The revised listing 
is for ortho-toluidine, which was previously listed as reasonably 
anticipated to be a human carcinogen and is now listed as known to be a 
human carcinogen. The new listings in the 13th RoC are three 
substances--1-bromopropane, cumene, and pentachlorophenol and by-
products of its synthesis--each listed as reasonably anticipated to be 
a human carcinogen.
