This page provides access to references cited in the External Review Draft and the Final, “Nanomaterial Case Study: Nanoscale Silver in Disinfectant Spray”.
This nanomaterial case study, like similar documents on nano-titanium dioxide in drinking water disinfectant and sunscreen) and multiwalled carbon nanotubes uses the Comprehensive Environmental Assessment (CEA) approach and is responsive to the 2007 EPA Nanotechnology White Paper, which recommended that the Agency develop case studies to identify unique risk assessment considerations and research needs to support risk assessment efforts for nanomaterials.
This case study does not represent a completed or even a preliminary assessment of nano-Ag; rather, it and other, similar case studies (see links above) support research planning efforts for nanomaterials. The document is organized around the CEA framework, which structures available information pertaining to the product life cycle, transport, transformation and fate processes in environmental media, exposure-dose in receptors (i.e., humans, ecological populations, and the environment), and potential impacts in these receptors. It also includes other direct and indirect ramifications of both primary and secondary substances or stressors associated with a nanomaterial, when such information is available. The CEA approach is both a framework and a process; the external review draft of the document supported the latter aspect, which engaged stakeholders from diverse technical (e.g., toxicology, exposure science, atmospheric chemistry) and sector (e.g., industry, government, academia) backgrounds. Through a structured collective judgment method these expert stakeholders used the draft document to identify and prioritize research gaps that could inform future assessments and risk management efforts. Some of these research gaps pertain to nano-Ag in disinfectant spray, others to nano-Ag irrespective of its application, while still others may apply more widely to nanomaterials in general. Details on the research priorities that were identified can be found in a Workshop Summary Report located on the document website, and in Appendix D of the final case study. These and other research gaps identified through similar applications of CEA to nanomaterials are intended to inform ongoing research planning for nanotechnology in the general scientific community as well as at the EPA.
