In a February 5, 2010, letter to the U.S. Environmental Protection Agency (EPA) Office of Pesticide Programs, the Silver Nanotechnology Working Group (SNWG) provides its reactions to the recent Scientific Advisory Panel (SAP) report on nanosilver and other nanometal oxide pesticide products. In its letter, SNWG highlights a number of the statements and recommendations from the SAP report that it considers “highly relevant for the shaping of EPA policy towards nanosilver materials.” SNWG notes that nanosilver is not a new material; clarity is needed on EPA concept of nano; real-life conditions are essential for realistic risk assessment; EPA policy must allow for sustainable technology development; and SAP frequently confounded general “nano”-related issues and uncertainties with issues specific to nanosilver.

The Silver Nanotechnology Working Group (SNWG) issued a press release regarding its presentation to the U.S. Environmental Protection Agency’s (EPA) Scientific Advisory Panel (SAP) at its November 3-6, 2009, meeting. EPA asked the 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.” According to EPA, companies with an interest in marketing products that contain nanosilver and/or other nanometals or nanometal oxides as pesticides regulated under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) have approached the Office of Pesticide Programs (OPP) seeking product registration. SNWG’s analysis included the key conclusions that nanosilver is not a new material and that EPA has “safely and successfully” regulated nanosilver products for decades.
