On October 10, 2011, ACS Nano accepted an article entitled “Generation of Metal Nanoparticles from Silver and Copper Objects:  Nanoparticle Dynamics on Surfaces and Potential Sources of Nanoparticles in the Environment,” in which the authors monitor nanoparticles and their transformations under a variety of environmental conditions.  According to the authors, their studies reveal “unprecedented dynamic behavior” of silver nanoparticles on surfaces.  The authors...

The European Commission (EC) adopted on October 18, 2011, a Recommendation on the definition of a nanomaterial. The Recommendation “invites” member states, European Union agencies, and economic operators to use the following definition of nanomaterial “in the adoption and implementation of legislation and policy and research programmes concerning products of nanotechnologies”: 2.         “Nanomaterial” means a natural, incidental or...

The National Nanotechnology Initiative (NNI) will hold a webinar on October 20, 2011, to announce the release of the 2011 NNI Environmental, Health, and Safety (EHS) Research Strategy, and to discuss the development of the Strategy and its key focus areas. Dr. John Howard, Co-Chair of the Nanotechnology Environmental and Health Implications (NEHI) Working Group, will serve as the moderator. Panelists will include: Dr. Treye Thomas, NEHI Working Group Co-Chair; Dr. Shaun...

On October 11, 2011, Health Canada announced the availability of its Policy Statement on Health Canada’s Working Definition for Nanomaterials. Health Canada received 29 comments from stakeholders on its March 2010 Interim Policy Statement, which it revised based on stakeholders’ feedback. According to Health Canada, other revisions were prompted by developments in international norms, evolving scientific evidence, and regulatory program needs. Health Canada states...

On October 6, 2011, Senator Mark L. Pryor (D-AR) introduced the Nanotechnology Regulatory Science Act of 2011 (S. 1662), which is intended to address potential health and safety risks from products that contain nanotechnology materials. The bill would establish a program within the U.S. Food and Drug Administration (FDA) to assess the health and safety implications of using nanotechnology in everyday products and develop best practices for companies using nanotechnology. The legislation would...

The European Commission (EC) has asked the Scientific Committee on Consumer Safety (SCCS) to prepare a guidance document on the safety assessment of nanomaterials in cosmetics. In its request for guidance, the EC notes that a number of documents provide general guidance on the health risk assessment of manufactured nanomaterials, but experience with the assessment of specific substances is limited. The guidance, which is due February 2012, should address the essential...

On September 28, 2011, the U.S. Environmental Protection Agency (EPA) issued its final guidance on the weight-of-evidence (WoE) (Final WoE Guidance) analysis that it will use to evaluate the results of data submitted in response to test orders issued for Tier 1 screening under the Endocrine Disruptor Screening Program (EDSP). This WoE analysis, in turn, will be used to determine what substances merit further study under Tier 2 as substances that have the potential to interact with the estrogen,...

Australia’s National Industrial Chemicals Notification and Assessment Scheme (NICNAS) announced on September 28, 2011, the availability of a review of the 2007-2009 literature on toxicological and health effects relating to six nanomaterials. NICNAS commissioned the review and analysis of literature concerning fullerenes, carbon nanotubes, and nanoforms of zinc oxide, titanium dioxide, cerium oxide, and silver. According to NICNAS, it chose these nanomaterials because it...

During the September 23, 2011, Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) conference organized by the European Chemicals Agency (ECHA) and European Commission (EC), Astrid Schomaker, Directorate-General (DG) Environment, stated that the EC has been working on a definition of nanomaterials, and that it “should be coming after the summer.” The EC previously stated in a letter to the Dutch Environment Ministry that it would publish a definition by the end of...

The Office of Environmental Health Hazard Assessment (OEHHA) has posted comments received on its July 29, 2011, revised proposed regulation concerning the specification of hazard traits, environmental and toxicological endpoints, and other relevant data that are to be included in California’s Toxics Information Clearinghouse.  The California Department of Toxic Substances Control (DTSC) will use information from the Clearinghouse to help identify chemicals of concern in consumer...
