The National Nanotechnology Initiative (NNI) will hold two public webinars providing an overview of the key activities of U.S. government agencies in tackling the challenge of plastic waste in the environment. NNI states that the plastic waste issue includes more than just solid waste accumulation. According to NNI, the breakdown of bulk plastics to micro-

The National Nanotechnology Initiative (NNI) and the U.S. Environmental Protection Agency (EPA) will co-host a webinar on August 25, 2022, on Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) funding opportunities for water nanotechnologies. Small businesses and academic researchers will have an opportunity to hear from some of the federal agencies

The International Organization for Standardization (ISO) has published standard ISO/TR 21386, “Nanotechnologies — Considerations for the measurement of nano-objects and their aggregates and agglomerates (NOAA) in environmental matrices.”  The standard provides some considerations for the collection of environmental samples to be analyzed for manufactured NOAA, considerations to distinguish manufactured NOAA from background levels

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).”  ISO states that, to evaluate the inhalation toxicity of NOAA, it is important to consider certain parameters that make the toxicity testing relevant to human exposure. 

On November 21, 2016, the International Organization for Standardization (ISO) released ISO/TR 18637:2016, “Nanotechnologies — Overview of available frameworks for the development of occupational exposure limits and bands for nano-objects and their aggregates and agglomerates (NOAAs).”  ISO notes that occupational exposure limits (OEL) are generally substance-specific.  In some case, there is insufficient data
