Nanotechnologies. Considerations for the measurement of nano-objects and their aggregates and agglomerates (NOAA) in environmental matrices Ingestion-build-51215 excluding austenitic or austenoferritic steelsWhat is this standard about? This document provides some considerations for the collection of environmental samples to be analysed 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.
