What is ISO/TR 21386- Considerations for the measurement of nano-objects and their aggregates and agglomerates (NOAA) about?

ISO/TR 21386 discusses nanotechnologies. ISO/TR 21386 is an international standard that provides for the measurement of nano-objects and their aggregates and agglomerates (NOAA) in environmental matrices. ISO/TR 21386 provides some considerations for the collection of environmental samples to be analyzed for manufactured NOAA, considerations to distinguish manufactured NOAA from background levels of naturally occurring nanoscale particles of the same composition, and preparation procedures to aid in the quantification of manufactured NM in environmental matrices. I SO/TR 21386 assists with insights that require unique collection and analytical techniques specific to the composition of the particle. In addition, provides a review of published studies that report levels of NOAA in the environment and aspects of collection and sample preparation.
