-Considerations for the measurement of nano-objects, and their aggregates and agglomerates (NOAA), in the environment +Nanotechnologies -- Considerations for the measurement of nano-objects and their aggregates and agglomerates (NOAA) in environmental matrices
      196 Scope/description
-This document will provide considerations for the collection of environmental samples to be analysed for manufactured nano-objects, and their aggregates and agglomerates greater than 100 nm (NOAA), considerations to distinguish manufactured nanomaterials from background levels of naturally occurring nanoscale particles, and preparation procedures to aid in the quantification of manufactured nanomaterials in the environment. Environment means ambient air, surface water, sediment, soil, estuarine and marine waters and sediments. +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.

      203 Goal or need for this document
-As manufactured nano-objects, and their aggregates and agglomerates greater than 100 nm (NOAA) enter the environment via release from the manufacturing process, products that contain them or from effluent of wastewater treatment facilities that may have received nanomaterials, there is an interest in determining their concentration in the environment. Such efforts require an understanding of the occurrence of natural materials that may interfere with the analysis or skew the results, and some strategies may require unique sampling and analytical techniques peculiar to thecomposition of the material. +As manufactured nano-objects, and their aggregates and agglomerates greater than 100 nm (NOAA) enter the environment via release from the manufacturing process, products that contain them or from effluent of wastewater treatment facilities that may have received nanomaterials, there is an interest in determining their concentration in the environment.
