The Finnish Institute of Occupational Health released a report in October 2013 entitled Evaluation of the health effects of carbon nanotubes. According to the Institute, recent studies have suggested that some types of multiwalled carbon nanotubes (MWCNT) have similar effects as asbestos.  The Institute states that the report “shows that rigid, long and needle-like MWCNTs induce inflammation and DNA damage in the lungs and in cultured cells, while flexible, long and tangled MWCNTs do not....

On November 19, 2013, the National Science and Technology Council, Committee on Technology, and Subcommittee on Nanoscale Science, Engineering, and Technology requested public comments on the draft 2014 National Nanotechnology Initiative Strategic Plan. The Strategic Plan provides the framework within which each National Nanotechnology Initiative (NNI) agency will carry out its nanotechnology programs and is intended to sustain coordination of interagency activities. The Strategic Plan...

In November 2013, Switzerland’s Federal Office of Public Health (FOPH) updated its precautionary matrix for synthetic nanomaterials, which industry can use to assess nano-specific health and environmental risks of nanoproducts. FOPH states that the precautionary matrix “enables the structured assessment of the ‘nano-specific need for precautions’ when handling synthetic nanomaterials.” FOPH intends the matrix to assist industry with due diligence requirements, and their “duty to...

Japan’s National Institute of Advanced Industrial Science and Technology (AIST) announced in October 2013 a voluntary guidance document on measuring airborne carbon nanotubes (CNT) in workplaces. The Technology Research Association for Single Wall CNTs (TASC), a consortium of nine companies and AIST, prepared the guidance, which is intended to provide a means of CNT safety management.  The guidance summarizes the available practical methods for measuring airborne CNTs:  (1) on-line...

The Air & Waste Management Association (A&WMA) is currently seeking authors, presenters, and panelists for its 107th Annual Conference and Exhibition, which will be held June 24-27, 2014, in Long Beach, California.  The A&WMA Intercommittee Task Force (ITF) on Nanoscale Science and Engineering is sponsoring a track in the technical program that will span a wide array of subjects, including environmental policy, measurement, health effects, monitoring, management, and safety...

On November 8, 2013, the National Institute for Occupational Safety and Health (NIOSH) published a report entitled Current Strategies for Engineering Controls in Nanomaterial Production and Downstream Handling Processes, which identifies and describes strategies for the engineering control of worker exposure during the production or use of engineered nanomaterials. NIOSH notes that there are currently more than 1,000 nanomaterial-containing consumer products available, including “makeup,...

On November 7, 2013, the U.S. Court of Appeals for the Ninth Circuit granted in part and denied in part the Natural Resources Defense Council’s (NRDC) petition for review of the U.S. Environmental Protection Agency’s (EPA) conditional registration of HeiQ AGS-20 and AGS-20 U (collectively, AGS-20) nanosilver products. The court held that “substantial evidence” supported EPA’s decision to use the characteristics of toddlers rather than infants in determining whether AGS-20 placed...

The World Health Organization (WHO) recently published the report of the December 10-11, 2012, WHO expert meeting entitled Nanotechnology and human health: Scientific evidence and risk governance. The conclusion states that while “first generation nanomaterials are being used in a variety of applications and products, they do not seem to present an imminent public health issue.” The conclusion continues, however, and states: “Given the scientific uncertainty and still emerging...

On October 28, 2013, the Wilson Center announced that the updated Nanotechnology Consumer Products Inventory contains 1,628 consumer products that have been introduced to the market since 2005, which is a 24 percent increase since the last update in 2010. The Wilson Center states that the re-launched inventory “seeks to address scientific uncertainty with contributions from those involved with nanomaterials production, use, and analysis.” The Project on Emerging...

The U.S. Food and Drug Administration (FDA) Center for Drug Evaluation and Research (CDER) posted a blog item on October 24, 2013, concerning the use of nanotechnology to develop new drugs. According to the item, “[t]here are already many products made using materials at the nanoscale, including new kinds of clothing, packaging materials, and light-weight, but strong, building materials.” CDER conducted a series of risk assessment and risk management exercises concerning...
