Nano and Other Emerging Chemical Technologies Blog

On January 5, 2021, the National Institute for Occupational Safety and Health (NIOSH) posted a Science Blog item entitled “Understanding the Broad Class of Carbon Nanotubes and Nanofibers (CNT/F) Used or Produced in U.S. Facilities.”  The item summarizes a recently published article in the journal Particle and Fibre Toxicology, “Physicochemical characterization and genotoxicity of the broad class of carbon nanotubes and nanofibers used or produced in U.S. facilities” that...

The American Conference of Governmental Industrial Hygienists (ACGIH®) Threshold Limit Values for Chemical Substances (TLV®-CS) Committee has included carbon nanotubes on its 2021 list of chemical substances and other issues under study.  Being placed on the under study list indicates that the TLV®-CS Committee has selected carbon nanotubes for development of a threshold limit value (TLV®).  ACGIH® describes TLVs® as health-based values representing the...

On January 26, 2021, the Organization for Economic Cooperation and Development (OECD) will hold a webinar on Guidance Document on Aquatic and Sediment Toxicological Testing of Nanomaterials (No. 317).  The webinar will discuss the scope and use of the guidance document, which addresses practical aspects of carrying out valid tests on nanomaterials, and modifications or additions to OECD Test Guidelines procedures intended to improve the accuracy of test...

The Organization for Economic Cooperation and Development (OECD) published a report entitled Moving Towards a Safe(r) Innovation Approach (SIA) for More Sustainable Nanomaterials and Nano-enabled Products.  According to the Executive Summary, the report “presents common working descriptions to ensure a common understanding of concepts such as: Safe(r) Innovation Approach and its elements, Safe(r)-by-Design and Regulatory Preparedness.”  The report compiles existing risk...

The Organization for Economic Cooperation and Development (OECD) has posted a report entitled Ability of biopersistent/biodurable manufactured nanomaterials (MNs) to induce lysosomal membrane permeabilization (LMP) as a prediction of their long-term toxic effects.  The report describes “the expanding knowledge on the implications and biological significance of lysosomal and autophagy dysfunction and the subsequent assembly and activation of inflammasome NLRP3 induced by biodurable...

In 2016, the Organization for Economic Cooperation and Development’s (OECD) Working Party on Manufactured Nanomaterials (WPMN) included the Advancing Adverse Outcome Pathway (AOP) Development for Nanomaterial Risk Assessment and Categorization (NanoAOP) project in its program of work.  The objective of the project is to contribute to the future development and application of AOPs for manufactured nanomaterial regulatory decision making by following the principles established by the OECD...

The European Union (EU) Observatory for Nanomaterials (EUON) is conducting a web satisfaction survey.  EUON provides information on the safety, innovation, research, and uses of nanomaterials on the EU market.  It is intended for stakeholders developing policies in the area, consumers, industry representatives, and non-governmental organizations.  EUON is funded by the European Commission (EC) and hosted and maintained by the European Chemicals Agency (ECHA).  Information from the survey...

On December 1, 2020, the French Agency for Food, Environmental and Occupational Health and Safety (ANSES) announced the results of an assessment of R-Nano, France’s national reporting scheme for substances in nanoparticle form.  In 2013, France began requiring companies that manufacture, import, and/or distribute a “substance with nanoparticle status” in an amount of at least 100 grams per year to submit an annual report with substance identity, quantity, and use...

On December 3, 2020, a workshop will be held on “Creating a NanoRisk Governance Council:  Stakeholder evaluation and feedback.”  The workshop is aimed at working with stakeholders to obtain their feedback on the services and on the four scenarios being discussed for the establishment of the proposed NanoRisk Governance Council.  The workshop will comprise a plenary session plus up to four breakout sessions.  Some information about the scenarios will be provided prior...

The European Union (EU) Observatory for Nanomaterials (EUON) announced on November 16, 2020, the results of a study on how citizens perceive nanomaterials and their potential risks to human health and the environment.  According to EUON, the study found that general awareness about the nature, characteristics, and properties of nanomaterials is low.  EUON notes that the level of awareness has increased compared to earlier surveys, however, and is expected to continue...
