NTP Board of Scientific Counselors Reviews Nomination of Nanoscale Silver for Testing

Lynn L. Bergeson

At its June 22, 2007, meeting, the National Toxicology Program’s (NTP) Board of Scientific Counselors (BSC) reviewed nominations of several substances for testing, including nanoscale silver. The Food and Drug Administration nominated nanoscale silver for toxicological studies “based on (a) increasing widespread use in drug, food and cosmetic products, and (b) the general lack of data on the toxicology and pharmacokinetics of these materials.” Comments on the testing nomination were submitted by the People for the Ethical Treatment of Animals (PETA) and the Physicians Committee for Responsible Medicine (PCRM); the Nano Testing Consortium; and the Silver Institute.
