Peer Consultation on Materials Characterization of Nanoscale Materials: September 6-7, 2007
Note: EPA no longer updates this information, but it may be useful as a reference or resource.
EPA has announced in the Federal Register a "peer consultation" to gather information on characterizing nanomaterials. The meeting will be held Thursday, September 6 and Friday, September 7, 2007 in Arlington, Va.
The meeting's goal is to help develop EPA's Nanoscale Materials Stewardship Program under the Toxic Substances Control Act (TSCA). It's one of several actions EPA has been taking to gather information to better understand potential risks and benefits of nanotechnology.
EPA is requesting comment on:
- Characteristics currently used or potentially available to characterize nanoscale materials;
- Rationale for the use of these characteristics; and
- Issues to consider regarding use of these characteristics in the Nanoscale Materials Stewardship Program
- For more information please see the Federal Register.
A growing class of materials known as engineered nanoscale materials, or nanoscale substances, have structures with the dimensions of roughly one to 100 nanometers, a size at which unique phenomena enable novel applications. A nanometer is about one ten-thousandth the diameter of a human hair. Many of these are regarded as "chemical substances" under TSCA.
On October 18, 2006, EPA launched a collaborative process and invited stakeholders to participate in the design, development, and implementation of a Nanoscale Materials Stewardship Program under TSCA. Its goal is to provide a firmer scientific foundation for regulatory decisions by encouraging the development of key scientific information and appropriate risk management practices for nanoscale materials.
