OECD Revises Guidance on Testing of Manufactured Nanomaterials

The Working Party on Manufactured Nanomaterials (“WPMN”) of the Organisation for Economic Co-operation and Development (“OECD”) has revised its nanomaterial testing guidance document, first published in 2009 to support nanotechnology safety in the industry.

The guidance manual was conceived primarily to assist sponsors of the OECD Sponsorship Programme for the Testing of Manufactured Nanomaterials, who conduct testing in support of the WPMN's exploratory testing program. The manual addresses includes general and common issues in nanomaterials safety as well as specific consideration on sample preparation and dosimetry for the safety testing of manufactured nanomaterials. Specific consideration includes  i) physic-chemical properties; ii) ecotoxicity studies; iii) degradation, transformation and accumulation; and iv) health effects.

EPA Scientific Advisory Panel to Discuss Nanoscale Silver at Public Meeting

A much valued contributor from CyberRegs provided us with the following information from the Federal Register that may be of interest to readers:

There will be a 4-day consultation meeting of the Federal Insecticide, Fungicide, and Rodenticide Act Scientific Advisory Panel (FIFRA SAP) to consider and review a set of scientific issues related to the assessment of hazard and exposure associated with nanosilver and other nanometal pesticide products.

DATES: The consultation meeting will be held on November 3 - 6, 2009, from approximately 8:30 a.m. to 5:00 p.m. The consultation meeting will be held at the Environmental Protection Agency, Conference Center, Lobby Level, One Potomac Yard (South Bldg.), 2777 S. Crystal Dr., Arlington, VA 22202.
