Nickel Nanoparticles Nominated for Listing in Report on Carcinogens

Lynn L. Bergeson

On September 20, 2013, the National Toxicology Program (NTP) published a Federal Register notice requesting information on 20 substances, mixtures, and exposure circumstances, including nickel nanoparticles, nominated for possible review for future editions of the Report on Carcinogens (RoC). NTP seeks information concerning:  (1) data on current production, use patterns, and human exposure; (2) information about published, ongoing, or planned studies related to evaluating carcinogenicity; (3) scientific issues important for assessing carcinogenicity of the substance; and (4) names of scientists with expertise or knowledge about the substance. The 12th RoC lists nickel compounds as “known to be human carcinogens.” Metallic nickel is listed as “reasonably anticipated to be a human carcinogen.” Information on nickel nanoparticles is due October 18, 2013.
