Environment Canada (EC) and Health Canada (HC) have released a document entitled Proposed Regulatory Framework for Nanomaterials Under the Canadian Environmental Protection Act, 1999 (Proposed Framework). EC/HC will hold a public workshop for stakeholders regarding the Proposed Framework on September 27, 2007, in Toronto. At the workshop, EC/HC will gather comments from participating stakeholders through discussion groups and plenary sessions. EC/HC will invite all...

The European Commission (EC) Directorate General for Health and Consumer Protection retained GreenFacts to summarize the EC’s 2006 report entitled Modified Opinion (After Public Consultation) on the Appropriateness of Existing Methodologies to Assess the Potential Risks Associated with Engineered and Adventitious Products of Nanotechnologies. According to GreenFacts, the EC’s Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) wrote its Opinion for a...

On August 14, 2007, the Department of Health and Human Services (DHHS) published a Federal Register notice announcing the 30th meeting of the President’s Council on Bioethics. The agenda items listed in the notice include “continue the exploratory phase of a potential inquiry into ethical issues associated with nanotechnology with expert presentations and Council discussions.” The meeting will be September 6-7, 2007....

On August 3, 2007, EHP-in-Press posted an article entitled “Nanosize Titanium Dioxide Stimulates Reactive Oxygen Species in Brain Microglia and Damages Neurons, In Vitro.” The article describes the in vitro neurotoxicity of P25, a commercially available titanium dioxide nanomaterial. According to the study, P25 appears to be non-toxic to isolated N27 neurons, but stimulates BV2 microglia to produce reactive oxygen species and damages oxidative...

The National Institute for Occupational Safety and Health (NIOSH) has posted several material safety data sheets (MSDS) for nanomaterials in its Nanoparticle Information Library (NIL). The goal of the NIL is to help occupational health professionals, industrial users, worker groups, and researchers organize and share information on nanomaterials, including their health and safety-associated properties.  To view the MSDSs, enter msds in the search field....

On August 8, 2007, the European Commission (EC) released the scientific opinion of the Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) on the appropriateness of the risk assessment methodology in accordance with the European Union’s (EU) technical guidance documents for new and existing substances for assessing the risks of nanomaterials. SCENIHR concluded that modifications to the existing technical guidance documents are necessary because special...

On May 11, 2007, the United Kingdom (UK) Health & Safety Executive (HSE) published its first bulletin on nanotechnology research. The bulletin is intended to provide an overview of published studies that have examined the exposure and potential health effects of nanomaterials, particularly in the occupational setting. According to HSE, inevitably there will be some overlap between studies of exposure of other groups (i.e. consumers).  HSE screened the literature search...

On April 11, 2007, the European Commission (EC) announced that the report prepared by the Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) regarding the appropriateness of the risk assessment methodology for assessing the risks of nanomaterials is available for comment. Comments are due May 23, 2007. EC states that the report “provides the Commission with a sound scientific approach on how to modify the Technical Guidance Documents of the EU...

In a March 15, 2007, letter, the Senate Committee on Commerce, Science, and Transportation and the Congressional Nanotechnology Caucus requested that the Government Accountability Office (GAO) review the National Nanotechnology Initiative (NNI), which was created to accelerate the discovery, development, and deployment of nanoscale science and technology. For fiscal year 2006, NNI received $1.2 billion in research and development funding, and 22 federal agencies, including the...
