The U.S. Environmental Protection Agency (EPA) announced on October 5, 2022, a new effort under the Toxic Substances Control Act (TSCA) to implement a streamlined and more efficient process under the New Chemicals Program to assess risk and apply mitigation measures, as appropriate, for new chemicals with applications in batteries, electric vehicles, semiconductors, and renewable energy generation. The new process is for mixed metal oxides (MMO), including new and modified...

On September 13, 2022, the European Union (EU) Observatory for Nanomaterials (EUON) published a Nanopinion entitled “Can the Brain’s Gatekeeper Fight a Nano-Attack?” by Dr. Eugenia (Éva) Valsami-Jones, Professor of Environmental Nanoscience at the University of Birmingham, who co-authored an article entitled “Biotransformation modulates the penetration of metallic nanomaterials across an artificial blood–brain barrier model.” The researchers set out to explore systematically how...

The U.S. Environmental Protection Agency (EPA) announced on September 8, 2022, that it selected 39 recipients that will receive nearly $12 million in pollution prevention (P2) grants made possible by President Joseph Biden’s Bipartisan Infrastructure Law’s $100 million program investment. According to EPA, the grants will allow states and Tribes to provide businesses with technical assistance to help them develop and adopt P2 practices to prevent or reduce pollution before it is even...

 By Lynn L. Bergeson and Carla N. Hutton   The U.S. Department of Energy’s (DOE) Bioenergy Technologies Office (BETO) announced on August 11, 2022, that a research team from Pacific Northwest National Laboratory investigated how potassium in biomass feedstocks poisons a catalyst. The researchers focused their study on potassium, a common alkali metal found in biomass feedstocks, since previous analysis of deactivated catalysts after catalytic fast pyrolysis (CFP) of woody biomass...

The National Academies of Sciences, Engineering, and Medicine (NASEM) released on August 9, 2022, a report entitled Review of Fate, Exposure, and Effects of Sunscreens in Aquatic Environments and Implications for Sunscreen Usage and Human Health. NASEM was tasked by Congress and funded by the U.S. Environmental Protection Agency (EPA) to undertake a consensus study of the potential risk of ultraviolet (UV) filters on already threatened aquatic environments and the potential...

The U.S. Environmental Protection Agency (EPA) published on June 29, 2022, the final scope of the risk evaluation to be conducted for Asbestos Part 2: Supplemental Evaluation Including Legacy Uses and Associated Disposals of Asbestos. 87 Fed. Reg. 38746. EPA will evaluate the conditions of use (COU) of asbestos, including other types of asbestos fibers in addition to chrysotile, that EPA had excluded from Part 1 as legacy uses and associated disposals, as well as any COUs of...

The U.S. Environmental Protection Agency’s (EPA) Office of Resource Conservation and Recovery (ORCR) published a request for information (RFI) on June 9, 2022, seeking information on the end-of-life management of batteries, including their generation, collection, recycling, and reuse, as well as the current labeling standards and requirements for batteries regarding their end-of-life. 87 Fed. Reg. 35202. According to the RFI, EPA is developing best practices with respect to the collection...

According to a May 9, 2022, news item published by the U.S. Environmental Protection Agency (EPA), “Advancing EPA’s Understanding of the Next Generation of Pesticides,” over the past decade, EPA “has received an increasing number of pesticide product applications that potentially contain nanomaterials.” The article notes that EPA’s current pesticide review method was not designed for nanomaterials, so each product is reviewed on a case-by-case basis. An EPA research team led by EPA...

The European Union (EU) Observatory for Nanomaterials (EUON) has launched two calls for tenders to conduct studies on nanomaterials. The first call for tender is on valid in silico modeling tools and read-across approaches, including creating case studies on read-across for specific types of nanomaterials. According to the call for tender, the study proposes to examine the use of these tools for nanomaterials and to draw potential conclusions (for both regulators and industry/small-...
