On May 6, 2011, the U.S. Environmental Protection Agency (EPA) promulgated a final significant new use rule (SNUR) under Section 5(a)(2) of the Toxic Substances Control Act (TSCA) for the chemical substance identified generically as multi-walled carbon nanotubes (MWCNT), which was the subject of premanufacture notice (PMN) P-08-199. Under the final SNUR, persons intending to manufacture, import, or process MWCNT for a use that is designated as a significant new use by the final rule must...

In an important and little noticed May 3, 2011, Federal Register notice, the U.S. Department of Commerce (DOC) International Trade Administration (ITA) requested public comments concerning regulatory cooperation between the U.S. and the European Union (EU) that would help eliminate or reduce unnecessary divergences in regulation and in standards used in regulation that impede U.S. exports.  Of critical importance, the ITA plainly recognizes and acknowledges that the main impediments to...

In its 2011 position statement on sunscreens, the Nanodermatology Society states that it “believes that nano-based sunscreens do not pose serious health risks to consumers,” and agrees with the Environmental Working Group (EWG) that “[z]inc and titanium-based formulations are among the safest, most effective, sunscreens on the market.” According to the position statement, this is based on the current evidence showing: Consumers using zinc and titanium sunscreen...

On April 21, 2011, the United Kingdom’s (UK) Food Standards Agency (FSA) published a report of consumers’ views on the use of nanotechnology in food and food packaging. FSA convened a focus group in late 2010 and early 2011, and asked participants about their views on nanotechnology. According to FSA, the main findings are that: Participants’ reactions to nanotechnology and food reflected a variety of concerns. These included whether this was a necessary development,...

Environmental Science & Technology posted on April 5, 2011, an article entitled “Behavior of Metallic Silver Nanoparticles in a Pilot Wastewater Treatment Plant.” The abstract states: We investigated the behavior of metallic silver nanoparticles (Ag-NP) in a pilot wastewater treatment plant (WWTP) fed with municipal wastewater.  The treatment plant consisted of a nonaerated and an aerated tank and a secondary clarifier.  The average hydraulic retention time including...

Inhalation Toxicology has published an article entitled “Exposure assessment of workplace manufacturing nanosized TiO2 and silver,” which monitored the possible exposure to nanoparticles at workplaces that manufacture nano-titanium dioxide (TiO2) and nano-silver.  The abstract states: To estimate the potential exposure of workers, personal sampling, area monitoring, and real-time monitoring using a scanning mobility particle sizer (SMPS) and dust monitor were conducted at...

On April 12, 2011, the German Federal Institute for Risk Assessment (BfR) issued a statement entitled “Safety of Nano Silver in Consumer Products: Many Questions Remain Open,” which reports BfR’s conclusions from a February 2011 workshop discussing existing risks and possible options for comprehensive consumer protection from nanosilver. According to BfR, “the situation continues to be characterised by the fact that not enough secured scientific findings about the specific effects of...

The Strategic Approach to International Chemicals Management (SAICM) Secretariat seeks input from stakeholders by May 1, 2011, for a forthcoming report on nanotechnologies and manufactured nanomaterials, which will focus on issues relevant to developing countries and countries with economies in transition. The report will include ten sections, covering beneficial uses of nanomaterials for health and the environment; economic and social impact; and work of international organizations. A...

On April 14, 2011, the House Science, Space, and Technology Subcommittee on Research and Science Education held a hearing entitled “Nanotechnology: Oversight of the National Nanotechnology Initiative and Priorities for the Future.” Witnesses included: Dr. Clayton Teague, Director, National Nanotechnology Coordination Office (NNCO); Dr. Jeffrey Welser, Director, Nanoelectronics Research Initiative, Semiconductor Research Corporation; Dr. Seth Rudnick, Chairman of the Board, Liquidia...

On April 6, 2011, several members of the NanoSafety Consortium submitted to the U.S. Environmental Protection Agency (EPA) a proposed testing agreement under Section 4 of the Toxic Substances Control Act (TSCA). Under the proposed testing agreement, the substances to be tested may include multi-walled carbon nanotubes, double-walled carbon nanotubes, single-walled carbon nanotubes, and graphene nanoplatelets. Participants would conduct 90-day inhalation toxicity studies in rats, and submit...

On April 14, 2011, the House Committee on Science, Space, and Technology Subcommittee on Research and Science Education will hold a hearing entitled “Nanotechnology:  Oversight of the National Nanotechnology Initiative and Priorities for the Future.” Witnesses will include: Dr. Clayton Teague, Director, National Nanotechnology Coordination Office; Dr. Jeffrey Welser, Director, Nanoelectronics Research Initiative, Semiconductor Research Corporation; Dr. Seth Rudnick, Chairman of the...

The European Parliament (EP) and European Union (EU) Council failed to reach agreement on an update to the novel foods regulation, which would have updated the 1997 regulation to address several issues, including nanoscale ingredients in food. According to a March 29, 2011, press release, the EP and Council disagreed on labeling food from cloned animals and their descendents, as well as nanotechnology. The draft legislation passed by the EP in July 2010 would have banned nanoscale...

On March 25, 2011, the National Research Council (NRC) announced the availability of a report entitled Prudent Practices in the Laboratory, which updates NRC’s guidelines on the safe use of hazardous chemicals. NRC last updated the guidelines in 1995, and the new edition includes new topics, including the handling of nanomaterials. The update sets out general guidelines for the management of nanomaterials. NRC developed the guidelines “from accepted chemical hygiene protocols for...
