Nominate a Substance

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 Report on Carcinogens.

You can nominate a substance, an agent, mixture or exposure circumstance for listing or delisting in the report using an online form.

If possible, include the rationale for evaluating the reviewing the nominated substance for the Report on Carcinogens and information supporting that rationale such as journal articles, NTP Technical Reports, IARC listings, exposure surveys, or release inventories, and unpublished data. The rationale and supporting information is helpful for the review of your nomination.
