An interesting document was published by United States Environmental Protection Agency: pdf format :click here
This document is part of continuing efforts by the U.S. Environmental Protection Agency (EPA) to understand the scientific issues and information gaps associated with nanotechnology, consistent with recommendations in the U.S. EPA Nanotechnology White Paper (2007) and U.S. EPA Nanomaterial Research Strategy (2009a). While no national or international consensus definition yet exists for nanomaterials, a current working definition is a material having at least one dimension on the order of approximately 1 to 100 nm (NSTC, 2011). Materials are intentionally engineered at the nanoscale to exploit the unique or novel properties that can arise from their small size.
The specific nanomaterials considered in this document are multiwalled carbon nanotubes (MWCNTs), as incorporated into flame-retardant coatings for upholstery textiles. This case study does not represent a completed or even preliminary assessment, nor is it intended to serve as a basis for near-10 term risk management decisions on possible uses of MWCNTs. Rather, the intent is to describe what is known and unknown about MWCNTs in this selected application as part of a process to identify and prioritize scientific and technical information to support future assessment and risk management efforts…
