(Beilstein J Nanotechnol 6:1769–1780, 2015) and Hansen et al. While additional work and resources are needed to improve these inventories, some initial trends have become evident through recent assessments of the CPI and Nanodatabase published by Vance et al. This chapter informs others in this book by looking specifically at what we have learned through the process of curating inventories of nano-enabled products, particularly in the US and Europe. These inventories were intended to provide relevant information about consumer products that may contain engineered nanomaterials (ENMs) and thereby, based on precautionary principle and the potential for the release of ENMs (either intentionally or unintentionally), may pose unique risks to end users and environmental systems.
Those inventories are: (1) the Nanotechnology Consumer Products Inventory (CPI) developed in 2005 by the Woodrow Wilson International Center for Scholars’ (WWICS) Project on Emerging Nanotechnologies (PEN) and (2) the Danish Nanodatabase established in 2012 by the Technical University of Denmark’s Department of Environmental Engineering (DTU Environment). Two inventories are considered especially important and are widely cited in peer-reviewed publications, grant applications, conferences and symposia, and the media. Given the challenges of simply defining the boundaries of what are or are not “nano” products, the concept of nano-specific consumer product inventories has arguably been one of the most important results from more than a decade of international investment in nanotechnology risk-related research, tools, and resources.
