The U.S. Environmental Protection Agency (EPA) is seeking comments on an external review draft document titled “Nanomaterial Case Study: A Comparison of Multiwalled Carbon Nanotubes and Decabromodiphenyl Ether Flame-Retardant Coatings Applied to Upholstery Textiles.” While the document does not apparently “draw conclusions regarding potential environmental risks or hazards of multiwalled carbon nanotubes, … it aims to identify what is known and unknown about [them] to support future assessment efforts.” The agency will also conduct a public information exchange meeting to receive comments and questions on the case study on October 29, 2012. Comments are requested by August 31, 2012. See Federal Register, July 2, 2012.
