ISO Standard Describes Aerosol Generation for Air Exposure Studies of Nano-Objects and Their Aggregates and Agglomerates

Posted in International, Research
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.  Three critical… Continue Reading

ISO Standard Provides Overview of Frameworks for Developing OELs and OEBs for NOAAs

Posted in International, Occupational Health and Safety Issues
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 to develop… Continue Reading
