EPA Nanomaterial Case Study Compares Multiwalled Carbon Nanotube and Decabromodiphenyl Ether Flame-Retardant Coatings Applied to Upholstery Textiles

The U.S. Environmental Protection Agency (EPA) announced on July 2, 2012, the availability of an external review draft document entitled Nanomaterial Case Study: A Comparison of Multiwalled Carbon Nanotube and Decabromodiphenyl Ether Flame-Retardant Coatings Applied to Upholstery Textiles (EPA/600/R-12/043A). EPA states that the draft document “does not draw conclusions regarding potential environmental risks or hazards of multiwalled carbon nanotubes (MWCNT); rather, it aims to identify what is known and unknown about MWCNT to support future assessment efforts.” On October 29, 2012, EPA will hold a public information exchange meeting to: (1) receive comments and questions on the draft document; and (2) provide information on the draft EPA nanomaterial case study and the workshop process that the draft document will be used in for identifying and prioritizing research gaps that could support future assessment and risk management efforts for MWCNT. Following the conclusion of the October 29 meeting, RTI International, an EPA contractor, will conduct a separate meeting on the “Nanomaterial Case Study Workshop Process: Identifying and Prioritizing Research for Multiwalled Carbon Nanotubes”' in the same location. EPA states that the workshop will be conducted independently by RTI International, with a set of invitee-only expert participants selected by RTI International, and will use a “structured decision science process” similar to the process used in previous workshops on nanoscale titanium dioxide in water treatment and in topical sunscreen and nanoscale silver in disinfectant spray. The RTI workshop will be open to public observers. Written comments on the draft document are due August 31, 2012. Registration for the public information exchange meeting will close on October 15, 2012. Space is limited, and reservations will be accepted on a first-come, first-served basis.
