According to the Office of the Federal Register, tomorrow the U.S. Environmental Protection Agency (EPA) will publish a notice regarding the Toxic Substances Control Act (TSCA) requirements potentially applicable to carbon nanotubes (CNT). EPA states that it “generally considers CNTs to be chemical substances distinct from graphite or other allotropes of carbon listed on the TSCA Inventory.” As a result, many CNTs may therefore be new chemicals under TSCA Section 5. Manufacturers or...

EPA Issues Consent Order for Multiwalled Carbon Nanotubes
The Environmental Defense Fund (EDF) recently posted two blog items regarding a consent order negotiated by the U.S. Environmental Protection Agency (EPA). The October 9, 2008, item states that EPA intends to issue a sanitized version of a consent order negotiated with a producer of multiwalled carbon nanotubes (MWCNT). According to EDF, the order was prompted by EPA’s review of a premanufacturing notification (PMN). EDF obtained a redacted copy of the consent order, and...

Friends of the Earth Australia Calls for an Immediate Moratorium on the Use of Carbon Nanotubes
In its latest Background Paper, entitled Mounting Evidence That Carbon Nanotubes May Be the New Asbestos, Friends of the Earth Australia (FOEA) is calling “for an immediate moratorium on the commercial use of carbon nanotubes and the sale of products that incorporate nanotubes until research can demonstrate whether or not there is any safe level of exposure to them.” FOEA also is calling for new nanotechnology-specific regulation to protect human health and the...

IARC Announces Carbon Nanotubes Nominated for Review
The International Agency for Research on Cancer (IARC) recently solicited nominations for substances for review in future IARC Monographs, which identify environmental factors that can increase the risk of human cancer. IARC states that it will select substances for review based on: (a) evidence of human exposure; and (b) evidence or suspicion of carcinogenicity. The 51 substances nominated include carbon nanotubes, which received three nominations: Name...
On May 10, 2007, EHP-in-Press posted an article entitled “Reviewing the Environmental and Human Health Knowledge Base of Carbon Nanotubes.” The authors reviewed the currently available literature about the human health and environmental risk potential of carbon nanotubes (CNT). The authors also investigated the life cycle of the CNT, as release into different environmental compartments may occur at the production stages as well as the product’s usage and disposal...
