The August 25, 2011, issue of Nature includes a letter from Hermann Stamm, European Commission (EC) Joint Research Centre (JRC), Institute for Health and Consumer Protection (IHCP). In response to Andrew Maynard’s article entitled “Don’t define nanomaterials,” in the July 7, 2011, issue of Nature, Stamm argues that a definition of engineered nanomaterials for regulatory purposes is “urgently needed.” Maynard proposes that a “‘one size fits all’ definition of nanomaterials...

Earlier this month the Danish Environmental Protection Agency (DEPA) published a document entitled Survey on Basic Knowledge about Exposure and Potential Environmental and Health Risks for Selected Nanomaterials, which is intended to provide an overview of the existing knowledge about seven of the most common nanomaterials, their environmental and health properties, the use of those nanomaterials, and the possibility of exposure of humans and the environment.  DEPA selected fullerenes, iron,...

The National Nanotechnology Initiative (NNI) has posted the presentations from the March 10-11, 2011, workshop entitled “US-EU: Bridging NanoEHS Research Efforts,” which was intended to continue the robust dialogue between the U.S. and European Union (EU) on issues of shared concern pertinent to nanotechnology research initiatives. The workshop covered the following areas:...

The European Commission (EC) announced on July 13, 2011, that European Union (EU)-funded scientists have developed risk assessment criteria for engineered nanomaterials “that will help support experts in making innovation and policy decisions.” According to the EC, findings reveal that product design can affect the unintentional release of engineered nanomaterials. The scientists suggest that the risk assessment criteria should be used to assess and minimize potential risks, which the EC...

On July 19, 2011, the National Nanotechnology Initiative (NNI) announced the release of four reports from a series of workshops focusing on issues in the nanotechnology environmental, health, and safety (EHS) arena. According to NNI, the workshops were a part of an ongoing strategy to coordinate nanotechnology-related EHS research by convening experts from industry, academia, and the federal government to share the latest information and newest developments, to discuss the current...

On May 10, 2011, the European Food Safety Authority (EFSA) published a guidance document for the risk assessment of engineered nanomaterial (ENM) applications in food and feed. According to EFSA, the guidance “is the first of its kind to give practical guidance for addressing potential risks arising from applications of nanoscience and nanotechnologies in the food and feed chain.” The guidance covers risk assessments for food and feed applications, including food additives, enzymes,...

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 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: The witnesses emphasized the need for Congress to reauthorize the National Nanotechnology Initiative (NNI) to ensure that the U.S. remains the global leader in nanotechnology. Other countries, such as Japan, China, and South...

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...
