On the 15th of June, 2017, the European Commission (EC) published a catalogue of nanomaterials used in cosmetic products on the European Union market. Regulation (EC) No. 1223/2009 requires the EC to publish a catalogue of all nanomaterials used in cosmetics placed on the market, indicating the categories and foreseeable exposure conditions….. http://www.safenano.org/news/news-articles/ec-publishes-catalogue-of-nanomaterials-used-in-cosmetic-products-placed-in-the-eu-market/

The World Health Organization’s (WHO) International Program on Chemical Safety (IPCS) published a draft Environmental Health Criteria (EHC) Document, Principles and Methods to Assess the Risk of Immunotoxicity Associated with Exposure to Nanomaterials. …. http://www.safenano.org/news/news-articles/who-seeks-comment-on-draft-document-concerning-assessing-the-risk-of-immunotoxicity-associated-with-exposure-to-nanomaterials/

The International Organization for Standardization (ISO) recently published standard ISO/TR 19601:2017, “Nanotechnologies – Aerosol generation for air exposure studies of nano-objects and their aggregates and agglomerates (NOAA).”……… http://www.safenano.org/news/news-articles/iso-standard-describes-aerosol-generation-for-air-exposure-studies-of-nano-objects-and-their-aggregates-and-agglomerates/

On 1st June, 2017, the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety published meeting documents from the Expert Dialogue on “Opportunities and Risks of the Application of Nanotechnologies in the Construction Sector.” …….. http://www.safenano.org/news/news-articles/germany-publishes-expert-dialogue-report-on-application-of-nanotechnologies-in-the-construction-sector/

The anticaking agent E551 silicon dioxide, or silica, has been used widely in the food industry over the past 50 years. Now, however, researchers working on the National Research Programme “Opportunities and Risks of Nanomaterials” have discovered that these nanoparticles can affect the immune system of the digestive tract…… http://www.safenano.org/news/news-articles/nanoparticles-as-food-additives-improving-risk-assessment/

In a collaboration between Paris Lodron University of Salzburg (PLUS) and the Flemish Institute for Technological Research (VITO NV), researchers have developed a novel air-liquid interface exposure system, affectionately named the NAVETTA by its creator Dr Madl, for the exposure of aerosolised engineered nanoparticles to living cells….. http://www.safenano.org/news/news-articles/novel-in-vitro-inhalation-exposure-system-developed-at-the-university-of-salzburg/      

Imaging the size distribution of metal nanoparticles (NPs) in a tissue has important implications in terms of evaluating NP toxicity. Microscopy techniques used to image tissue NPs are limited by complicated sample preparation or poor resolution…. http://www.nature.com/articles/s41598-017-03275-x

Nanoparticles (NPs) size, surface functionalization, and concentration were claimed to contribute to distribution and toxicity outcomes of NPs in vivo. However, intrinsic chemical compositions of NPs caused inconsistent biodistribution and toxic profiles which attracted little attention. In this study, silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs) were used to determine the biodistribution, toxickinetic, and genotoxicity […]

The protest group “THONG”, this week, used Street-Theater tactics on Chicago’s Michigan Avenue to draw attention to one of the first commercial nano-tech involved consumer products, a branded line of stain and water repellant clothing. Looking at the store sign, can you guess who the target market is?…. https://www.treehugger.com/culture/nano-tech-street-protest-on-chicagos-magnificent-mile.html
