On August 15, 2023, the European Union (EU) Observatory for Nanomaterials (EUON) published a Nanopinion entitled “Nanocrystals Coating by Friction. A New Approach for Advanced Materials” by Dr. Bentejui Medina-Clavijo, Senior Fellow at the European Organization for Nuclear Research (CERN), and Professor Andrey Chuvilin, head of the Electron Microscopy Laboratory at nanoGUNE. According to the authors, it has been found that friction “can dramatically change the surface properties of a...

The U.S. Environmental Protection Agency (EPA) will hold a two-day training on its high throughput toxicokinetic (HTTK) R package as part of its New Approach Methods (NAM) Training Program: According to EPA, toxicokinetics (TK) provides a bridge between toxicity and exposure assessment by predicting tissue concentrations due to exposure. EPA notes that traditional TK methods can be resource intensive and require chemical-specific data. EPA states that its freely available HTTK R...

On July 27, 2023, the United Nations (UN) published an electronic version of the tenth revision (Rev 10) of the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) available for free for consultation purposes. The amendments to the ninth revision of the GHS (Rev 9) include the classification procedure for desensitized explosives (Chapter 2.17); the use of non-animal testing methods for classification of health hazards, in particular: skin corrosion/irritation...

On August 22, 2023, the U.S. Environmental Protection Agency (EPA) published ChemExpo, a free, publicly available search and visualization tool for exploring chemical use data relevant to exposure assessment that has been curated from public documents. According to EPA, the interactive web application focuses on data collected by EPA about how chemicals are used in commerce and how they occur in consumer and industrial products. EPA notes that under the Toxic Substances Control Act...

The Congressional Research Service (CRS) published an updated report on August 4, 2023, on the U.S. Department of Agriculture’s (USDA) Sustainable, Ecological, Consistent, Uniform, Responsible, Efficient (SECURE) rule. The revisions note that USDA’s Animal and Plant Health Inspection Service’s (APHIS) five-year Strategic Plan for fiscal years (FY) 2023-2027 states that “one of its objectives is to ensure the safe development of agricultural biotechnology products using a...

Comments submitted by The Toxic Substances Control Act (TSCA) New Chemicals Coalition (NCC) regarding the U.S. Environmental Protection Agency’s (EPA) proposed regulations to control health risks from chemicals made with waste plastic were featured by Bloomberg in a August 23, 2023 article.  [o]ther trade groups told the EPA its rules “would hinder development of advanced recycling projects and progress towards a more circular plastics economy.” The heat generated through the...

On August 23, 2023, Chemical Watch quoted Lynn L. Bergeson, Managing Partner, Bergeson & Campbell, P.C. (B&C®) regarding a new enforcement effort announced by the U.S. Environmental Protection Agency (EPA) imposing liability for PFAS pollution that would target not only manufacturers, but also users of the persistent substances.  Lynn Bergeson, managing partner at Bergeson & Campbell, said: “What you don’t know may hurt you, so be PFAS-aware and...

On August 22, 2023, Chemical Watch quoted Karin F. Baron, MSPH, Director of Hazard Communication and International Registration Strategy with Bergeson & Campbell, P.C. (B&C®) regarding preparing for notification deadlines as Chile’s Ministry of Environment (MMA) is set to begin compiling a national inventory of chemicals from August next year. That includes determining which substances are considered hazardous and require...

On September 26, 2023, Nano4EARTH will hold a roundtable discussion on batteries and energy storage. The roundtable will aim to identify fundamental knowledge gaps, needs, and opportunities to advance current electrification goals. According to the National Nanotechnology Initiative (NNI), by convening stakeholders from different sectors, backgrounds, and expertise, the roundtable is intended to identify applicable lessons across the spectrum of technologies and to discuss...

The U.S. Environmental Protection Agency (EPA) announced on August 17, 2023, its National Enforcement and Compliance Initiatives (NECI) for 2024-2027, “including for the first time initiatives to mitigate climate change, address exposure to [per- and polyfluoroalkyl substances (PFAS)] contamination, and protect communities from cancer-causing coal ash.” To advance the Biden Administration’s commitment to protect disadvantaged communities, EPA states that it also will...
