Should NTP Review Nanotech Toxicity?
The Department of Health and Human Services runs the National Toxicology Program. According to HHS, the NTP “actively seeks to identify and select for study chemicals and other substances for which sufficient information is not available to adequately evaluate potential human health hazards.”
The U.S. Food and Drug Administration has nominated “Nanoscale materials Nanoscale gold [7440-57-5] Nanoscale silver [7440-22-4]” for NTP review.
The Federal Register notice states that the Program is considering review of these Nanoscale materials for
“– Nanoscale materials characterization.
– Metabolism and pharmacokinetic studies
– Acute, subacute and subchronic toxicity studies.
– mechanistic studies to assess the role of size and surface coating on biological disposition and toxicity. “
The NTP seeks public comment by May 10, 2007, on whether they should review these nanoscale materials, and on whether they should review eight other materials identified in NTP’s March 29, 2007 Federal Register notice.
