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
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.
In an October 5, 2010, Chemical Gazette notice, the National Industrial Chemicals Notification and Assessment Scheme (NICNAS) announced that it is introducing new administrative processes for the notification and assessment of industrial nanomaterials that are considered to be new chemicals. The new administrative arrangements will be effective from January 1, 2011, and will apply to any new chemical that falls under the following working definition of “industrial nanomaterial”:
. . . industrial materials intentionally produced, manufactured or engineered to have unique properties or specific composition at the nanoscale, that is a size range typically between 1 [nanometer (nm)] and 100 nm, and is either a nano-object (i.e. that is confined in one, two, or three dimensions at the nanoscale) or is nanostructured (i.e. having an internal or surface structure at the nanoscale).
On November 9, 2009, Australia announced the availability of a public discussion paper proposing to strengthen regulation of industrial nanomaterials used in Australia. The National Industrial Chemicals Notification and Assessment Scheme (NICNAS) developed the proposal in conjunction with its Nanotechnology Advisory Group, which includes representatives from industry, the community, and research sectors. Major regulatory reforms would include:…
