On April 29, 2021, the European Union (EU) Observatory for Nanomaterials (EUON) published a Nanopinion entitled “Biotransformation of nanomaterials while transferring in the food chain” by Dr. Fazel A. Monikh.  As the application of nanomaterials increases, more of these materials are released in the environment.  Monikh states that some nanomaterials that are persistent in the environment raise concerns as they can enter organisms’ bodies, accumulate in their organs, and transfer through different trophic levels in food chains.  With the help of his collaborators and the support of the EU’s Horizon 2020, Monikh developed “a sensitive workflow to trace…

The Nanotechnology Industries Association (NIA) has published a March 2021 position paper, A changing regulatory landscape and language for the nanoscale, that examines the transition from “nanomaterial” to “nanoforms” to reflect better the differences in nanomaterial properties both in relation to bulk counterparts and to nanoforms of the same substance.  In the paper, NIA describes a transition phase where the language of nanoforms is used more widely and examples of nanoform sets can be increasingly demonstrated in the public domain, while there is still a “significant” learning curve for both industry and the European Chemicals Agency (ECHA).  NIA recommends…

On April 16, 2021, the European Commission (EC) Scientific Committee on Consumer Safety (SCCS) posted two preliminary opinions for comment:  Opinion on Gold (nano), Colloidal Gold (nano), Gold Thioethylamino Hyaluronic Acid (nano) and Acetyl heptapeptide-9 Colloidal gold (nano) and Opinion on Platinum (nano), Colloidal Platinum (nano) and Acetyl tetrapeptide-17 Colloidal Platinum (nano).  The EC asked SCCS whether the nanomaterials gold and colloidal gold, gold thioethylamino hyaluronic acid, and acetyl heptapeptide-9 colloidal gold are safe when used in leave-on skin cosmetic products according to the maximum concentrations and specifications, taking into account reasonably foreseeable exposure conditions.  SCCS states that it…

On April 12, 2021, the European Commission (EC) Scientific Committee on Consumer Safety (SCCS) published its final opinion on hydroxyapatite (nano).  The EC asked whether SCCS considers the nanomaterial hydroxyapatite safe when used in leave-on and rinse-off dermal and oral cosmetic products according to the maximum concentrations and specifications reported, taking into account reasonably foreseeable exposure conditions.  SCCS states that having considered the data provided, and other relevant information available in scientific literature, it “cannot conclude on the safety of the hydroxyapatite composed of rod-shaped nanoparticles for use in oral-care cosmetic products at the maximum concentrations and specifications given…

The International Organization for Standardization (ISO) published a news item on April 1, 2021, entitled “The Science of Tiny Little Things.”  According to the item, ISO has recently made some revisions and updates to its comprehensive 13-part series of International Standards for nanotechnology.  Updated standards include ISO/TS 80004-3, Nanotechnologies – Vocabulary – Part 3:  Carbon nano-objects, which defines terms and concepts for carbon nano-objects, ISO/TS 80004-6, Nanotechnologies – Vocabulary – Part 6:  Nano-object characterization, and ISO/TS 80004-8, Nanotechnologies – Vocabulary – Part 8:  Nanomanufacturing processes.  The item states that work is underway “to develop a standard that will consolidate some of…

The European Commission (EC) has requested a scientific opinion from the Scientific Committee on Health, Environmental and Emerging Risks (SCHEER) on the safety of titanium dioxide in toys with regard to a possible derogation from its prohibition.  The Toy Safety Directive 2009/48/EC prohibits the use of substances in toys if those substances are classified as carcinogenic, mutagenic, or toxic for reproduction (CMR).  The use of such substances may be permitted under certain conditions, however.  To permit the use of a CMR substance of category 2, the substance has to be evaluated by the relevant Scientific Committee and found to be…

The Society of Toxicology (SOT) in conjunction with the U.S. Food and Drug Administration (FDA) Center for Food Safety and Applied Nutrition (CFSAN) have partnered to provide a colloquia series on Emerging Toxicological Science:  Challenges in Food and Ingredient Safety.  The colloquia will present scientific information that is high-quality, cutting-edge, future-oriented toxicological science and is intended to provide a well-grounded foundation to inform the work of FDA employees.  On April 8, 2021, there will be a live webcast on the toxicology of nanoparticles.  Richard Canady, Ph.D., and Kapal Dewan, MS, CLSp(CG), are Colloquium Co-Chairs.  The agenda includes: Welcome, George Daston,…

NanoHarmony held a webinar on March 17, 2021, on “Identification and solving barriers for translating science to regulation and standards.”  According to NanoHarmony, the webinar focused on helping to identify the obstacles faced by stakeholders in developing new test methods and having them introduced as new test guidelines and guidance documents.  A recording of the webinar is now available online, as well as the following slides: Claus Svendsen, CEH, welcome and introduction; Eric Bleeker, National Institute for Public Health and the Environment (RIVM), “The OECD process: From knowledge generation to embedding in a test guideline or …

On March 19, 2021, the European Union (EU) Observatory for Nanomaterials (EUON) published a Nanopinion entitled “ECETOC task force ensures society benefits from safe nanomaterials via efficient safety assessments that require minimal animal testing” by authors from BASF and the Center for Chemical Safety Assessment (ECETOC).  The column reviews ways to assess the safety of nanomaterials while minimizing animal testing.  According to the authors, the NanoApp developed by the ECETOC Task Force on Nanomaterials helps users group similar nanoforms, which can be useful when registering nanoforms via sets of similar nanoforms, or when doing read-across between nanoforms for…

The European Union (EU) Observatory for Nanomaterials (EUON) announced on March 19, 2021, that it is looking for topic suggestions that could be addressed in its upcoming studies.  According to EUON, up to three studies are conducted annually to address knowledge gaps on nanomaterials that are of interest to the general public and the research community.  EUON states that it seeks studies that address: Questions relating to the health and safety of nanomaterials, including hazard and risk assessment, exposure to nanomaterials, or worker safety and protection; Specific issues surrounding the uses of nanomaterials; or Information about markets for nanomaterials (g.,…

Gov4Nano is a Horizon 2020 project that aims to design an effective risk governance process for nanotechnologies, including improving the availability of nano-relevant data.  To meet its aims, Gov4Nano is conducting a “Data Sharing and FAIR Data Use Survey” to obtain views and opinions from data users and producers on data availability and sharing and how these can be improved.  Gov4Nano seeks to determine how barriers to data availability can be lowered and incentives for data sharing can be raised.  According to Gov4Nano, the questionnaire will take five to ten minutes.  Gov4Nano states that the information provided will…

On March 4, 2021, the French Agency for Food, Environmental and Occupational Health and Safety (ANSES) announced that it is recommending an eight-hour occupational exposure limit (OEL) of 0.80 micrograms per cubic meter (µg/m3) for titanium dioxide nanoparticles.  According to ANSES, compliance with this value “should help prevent lung inflammation, an effect that occurs at the lowest exposure concentrations.”  Due to the lack of available data on the immediate or short-term effects of titanium dioxide nanoparticles, in accordance with its methodological guide, ANSES states that it also recommends not exceeding the concentration of 4.0 µg/m3 over a 15-minute period.  Compliance…
