The European Union (EU) Observatory for Nanomaterials (EUON) announced on May 20, 2020, that a recent study has analyzed existing research on whether nanomaterials used in consumer products and at workplaces are absorbed through the skin.  The study was commissioned by EUON and carried out by the RPA consortium of Triskelion and the Dutch National…

On April 12, 2020, the World Health Organization (WHO) published Environmental Health Criteria 244:  Principles and methods to assess the risk of immunotoxicity associated with exposure to nanomaterials.  WHO states that the document presents an overview of the current knowledge and evidence on principles and basic mechanisms of immunotoxicity caused by engineered nanomaterials (ENM). …

On May 5, 2020, the European Union (EU) Observatory for Nanomaterials (EUON) published a Nanopinion entitled “NanoApp helps navigate legal obligations under REACH.”  Olivier de Matos, Secretary General of the European Center for Ecotoxicology and Toxicology (ECETOC), describes the web-based app that was designed to help registrants follow the European Chemicals Agency’s (ECHA)…

The International Organization for Standardization (ISO) has published standard ISO/TS 21412:2020, “Nanotechnologies — Nano-object-assembled layers for electrochemical bio-sensing applications — Specification of characteristics and measurement methods.”  The standard specifies the characteristics to be measured of nano-object-assembled layers on electrodes by means of a solution process and of nano-objects constituting the layers for electrochemical…

On April 7, 2020, the European Union (EU) Observatory for Nanomaterials (EUON) published a Nanopinion entitled “Carbon Nanotubes — First nanomaterial of high concern on the SIN List.”  As reported in our November 27, 2019, blog item, ChemSec added carbon nanotubes to the Substitute It Now (SIN) List in November 2019.  According…

The International Organization for Standardization (ISO) has published standard ISO/TS 11308:2020, “Nanotechnologies — Characterization of carbon nanotube samples using thermogravimetric analysis.”  The standard provides guidelines for the characterization of carbon nanotube (CNT)-containing samples by thermogravimetric analysis (TGA), performed in either an inert or oxidizing environment.  The standard offers guidance on the purity assessment…

The International Organization for Standardization (ISO) has published standard ISO/TS 21237:2020, “Nanotechnologies — Air filter media containing polymeric nanofibres — Specification of characteristics and measurement methods.”  According to ISO, in recent years, air filter media containing nanofibers have been commercialized and widely used by different industries due to their high filtration efficiency, along…

The European Union (EU) Observatory for Nanomaterials (EUON) posted an article on April 6, 2020, announcing the availability of a study that found a lack of data on female fertility.  The study, A critical review of studies on the reproductive and developmental toxicity of nanomaterials, was commissioned by the European Chemicals Agency (ECHA) and…

On March 9, 2020, the Canadian Center for Occupational Health and Safety (CCOHS) posted a podcast entitled “The Hazards of Nanomaterials and How to Control Exposure.”  CCOHS states that nanomaterials have many useful properties, but the same properties that make them desirable in manufacturing present unique potential safety hazards when workers are exposed…

On March 23, 2020, the European Commission’s (EC) Scientific Committee on Consumer Safety (SCCS) announced that the fact sheet on the SCCS Guidance on the safety assessment of nanomaterials in cosmetics is now available in French, German, Italian, and Spanish.  The guidance provides recommendations for the safety assessment of nanomaterials intended for use in…
