According to the Toxics Use Reduction Institute’s (TURI) website, the Toxics Use Reduction Act (TURA) Program in Massachusetts has received a petition to list carbon nanotubes (both single-walled and multi-walled) and carbon nanofibers.  The TURA Science Advisory Board (SAB) is beginning the process of reviewing these substances and seeks additional information from stakeholders.  SAB’s

On September 17, 2020, the U.S. Environmental Protection Agency (EPA) published final significant new use rules (SNUR) under the Toxic Substances Control Act (TSCA) for chemical substances that were the subject of premanufacture notices (PMN) and are subject to Orders issued by EPA pursuant to TSCA.  85 Fed. Reg. 57968.  The SNURs require persons who

As reported in our February 5, 2020, blog item, the American Conference of Governmental Industrial Hygienists (ACGIH®) Threshold Limit Values for Chemical Substances (TLV®-CS) Committee included carbon nanotubes on its 2020 list of chemical substances and other issues under study.  Being placed on the under study list indicated that the

The International Chemical Secretariat (ChemSec) announced on November 14, 2019, that it added more chemicals, including carbon nanotubes, to its Substitute It Now! (SIN) List.  ChemSec describes carbon nanotubes as “one of the more well-studied nanomaterials” and notes that “they are used to make durable, lightweight materials, for electrical conductivity, as a super black pigment

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

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 environment, as well as for mandatory labeling of all nanoscale materials used in the workplace and in consumer products.

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:
