On August 18, 2021, the U.S. Environmental Protection Agency (EPA) issued several significant new use rules (SNUR) under the Toxic Substances Control Act (TSCA) for chemical substances that were the subject of premanufacture notices (PMN), including the chemical substance identified generically as multiwalled carbon nanotubes (PMN P-18-182). 86 Fed. Reg. 46133. The SNUR requires

As reported in our January 4, 2021, blog item, the American Conference of Governmental Industrial Hygienists (ACGIH®) Threshold Limit Values for Chemical Substances (TLV®-CS) Committee included carbon nanotubes on its 2021 list of chemical substances and other issues under study. Being placed on the under study list indicated that the

On July 13, 2021, the National Institute for Occupational Safety and Health (NIOSH) announced the availability of a draft technical report entitled Approaches to Developing Occupational Exposure Limits or Bands for Engineered Nanomaterials: User Guide and Technical Report. 86 Fed. Reg. 36748. NIOSH states that the draft report describes an evidence-based approach to

Registration has opened for a June 8, 2021, webinar held by the U.S. National Nanotechnology Initiative on “What We Know about NanoEHS: Human Health.” The webinar will feature experts from diverse disciplines who will share their perspectives on key findings on the effects of engineered nanomaterials on human health. Janet Carter, Senior Scientist,

The U.S. National Nanotechnology Initiative (NNI) will hold a webinar on June 2, 2021, on nanosensors for food and agriculture. NNI states that nanotechnology-enabled sensors (nanosensors) “are promising tools to advance precision agriculture and support a safe and robust food supply chain, from farm to fork.” Panelists will discuss how the development and deployment

The National Institute for Occupational Safety and Health (NIOSH) has published Current Intelligence Bulletin 70: Health Effects of Occupational Exposure to Silver Nanomaterials. According to the Current Intelligence Bulletin (CIB), NIOSH assessed potential health risk from exposure to silver nanomaterials by evaluating more than 100 studies of silver nanomaterials in animals or cells. The
