Wisconsin Legislature Considers Nanotechnology Registry

In a December 16, 2009, letter, three members of the Wisconsin Assembly requested that a Legislative Council study be conducted on the feasibility of creating a nanotechnology registry and the development of subsequent legislation to monitor the use, manufacture, and disposal of nanomaterials in Wisconsin. The letter, signed by State Representatives Terese Berceau (D), Chuck Benedict (D), and Penny Bernard Schaber (D), notes that entities manufacturing or using nanomaterials in Wisconsin are not required by state or federal regulation to identify materials they are using, how they transport and dispose of them, or where such work is taking place. According to the letter, data gaps present “serious concerns” to first responders and public agencies responsible for addressing health consequences or releases into air or water. The letter states: “The development of a registry in partnership with science, business, and the public sector -- and which enhances the economic development of our state -- is our ultimate goal.”

Bayer Material Sciences Announces OEL for Baytubes

Last month, Bayer Material Science (BMS) announced that it derived an occupational exposure limit (OEL) of 0.05 milligrams per cubic meter (mg/m3) for Baytubes, BMS multi-wall carbon nanotubes. According to BMS, “[t]he latest results of sub-chronic inhalation studies support the conclusion that Baytubes act like poorly soluble particles.” BMS derived the OEL based on previous single and recent repeated inhalation studies. BMS states: “All relevant information are now included in the updated Safety Data Sheet and will further ensure that our customers work safely with our Baytubes.”

NIOSH Announces Conference on Nanomaterials and Worker Health

The National Institute for Occupational Safety and Health (NIOSH) announced that it will hold a conference entitled “Nanomaterials and Worker Health:  Medical Surveillance, Exposure Registries, and Epidemiologic Research,” on July 21-23, 2010, at the Keystone Resort and Conference Center in Keystone, Colorado. According to NIOSH, the goal of the conference is to identify gaps in information and address questions focusing on occupational health surveillance, exposure registries, and epidemiologic research involving nanotechnology workers.  The conference will include invited and submitted papers, breakout sessions to allow for small group discussions, and poster presentation.

SNWG Presents Data on Silver and Nanotechnology to the SAP

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.
