On October 22, 2012, Safe Work Australia announced the availability of a report entitled Human Health Hazard Assessment and Classification of Carbon Nanotubes, as well as an information sheet on the report. The report recommends that multi-walled carbon nanotubes should be classified as hazardous unless toxicological or other data for specific types imply otherwise. The National

On August 1, 2012, the U.S. Environmental Protection Agency (EPA) posted a final report entitled Nanomaterial Case Study: Nanoscale Silver in Disinfectant Spray, which EPA states “is intended to be used as part of a process to identify what is known and, more importantly, what is not yet known that could be of value in

On April 30, 2012, the European Chemicals Agency (ECHA) announced the availability of three appendices, updating Chapters R.7a, R.7b, and R.7c of the Guidance on Information Requirements and Chemical Safety Assessment (IR & CSA). ECHA prepared a draft revision of the Guidance, based on the outcome of the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH)

On February 9, 2012, the U.S. Environmental Protection Agency (EPA) posted a summary report on its January 2011 workshop on nanoscale silver. The workshop was the second in a series conducted by the National Center for Environmental Assessment (NCEA) to further the development of a research strategy for completing comprehensive environmental assessments of nanomaterials.  The basis of the workshop was the report Nanomaterial Case Study:  Nanoscale Silver in Disinfectant Spray.  According to the summary report, the outcomes of this and future workshops in the series — prioritized information gaps and risk tradeoffs — will be used in developing and refining a long-term research strategy to assess potential human health and ecological risks of nanomaterials and to manage associated risks of specific nanomaterials.

A coalition of nonprofit consumer safety and environmental groups sued the Food and Drug Administration (FDA) in the U.S. District Court for the Northern District of California on December 21, 2011.  The coalition is led by the International Center for Technology Assessment (ICTA), and includes Friends of the Earth, Food and Water Watch, the Center

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 considers them “to already be in, or close to, commercial use in Australia.”  The goal of the review was to identify any available scientific evidence of important toxicological/health effects that had not been covered by the scope of previous reviews and therefore supplement currently available scientific information on these substances.

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

The Office of Environmental Health Hazard Assessment (OEHHA) announced on July 29, 2011, that it revised its proposed regulation concerning the specification of hazard traits, environmental and toxicological end-points, 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 products as part of its Green Chemistry Program. Comments are due September 12, 2011.

The Silver Nanotechnology Working Group (SNWG) prepared a May 2, 2011, statement regarding the German Federal Institute for Risk Assessment’s (BfR) April 12, 2011, statement concerning consumer products containing nanosilver. SNWG notes that, in December 2009, BfR published an opinion advising against the use of nanosilver in consumer products. Industry and other groups, including SNWG, asked BfR

Last week, the University of California, San Francisco’s (UCSF) Program on Reproductive Health and the Environment announced the publication of its “Recommendations for Addressing Potential Health Risks from Nanomaterials in California,” which provides recommendations for addressing potential health risks from nanomaterials to the Office of Environmental Health Hazard Assessment (OEHHA) and to the state of California.  OEHHA contracted with UCSF to prepare the report, which provides an overview of nanotechnology materials, potential exposures, and human-health risks, and recommendations for addressing potential health hazards and risks from nanotechnology. Recommendations include those that can be implemented under the existing regulatory structure of OEHHA, such as establishing a publicly accessible clearinghouse and inventory of nanomaterial sources and products. The report also includes recommendations that are outside the scope of OEHHA, many of which may require legislative changes, such as requiring testing of release and exposure potential for nanomaterials in existing and new consumer products, and implementing a labeling system that requires labeling of products that contain nanomaterials.  According to UCSF, the recommendations primarily focus on requiring information on potential exposures and health hazards for nanomaterials used in the marketplace.
