The NTP solicits and encourages the broadest participation from interested individuals or parties in nominating agents, substances, mixtures or exposure circumstances for listing in or delisting from the RoC.
You may nominate an agent, substance, mixture or exposure circumstance for listing or delisting in the RoC using an online form or by submitting the nomination to Dr. Ruth Lunn.
Your nomination must contain a rationale for listing or delisting as either a known to be human carcinogen or as reasonably anticipated to be a human carcinogen. Provide or reference supporting background information and relevant data when possible. Examples of supporting materials are journal articles, NTP Technical Reports, IARC listings, exposure surveys, or release inventories.
