Nanotechnology enables manufacturers to enhance the performance of products by incorporating materials that are in the scale of 1-100 nm. There are environmental and health questions about engineered nanomaterials that may be entering the environment from degradation of nano-enabled products, from degradation of waste from these products at the end of the life-cycle, and from waste materials generated during manufacturing. Measurement methods and instrumentation are nonspecific, making it difficult to differentiate between naturally occurring and engineered particles; furthermore, the background levels of naturally occurring materials in the nanoscale are unknown. Because the uncertainties in this area are high, the Industry Consortium of Environmental Measurement of Nanomaterials (ICEMN)(dagger) was formed to provide regulators ideas on how to develop methods and support these measurements. The reviews of the science that follow, initiated by the ICEMN organization and led by specific ICEMN members, are an approach to use. It is presented as a guide to regulatory scientists and others who are not engaged in direct research, but have a need to understand the complexities of developing data on environmental concentrations of engineered nanomaterials.
