EPA Releases Final Comprehensive Environmental Assessment Applied to MWCNTs in Flame-Retardant Coatings in Upholstery Textiles
The U.S. Environmental Protection Agency (EPA) posted on September 30, 2013, a final report entitled Comprehensive Environmental Assessment Applied to Multiwalled Carbon Nanotube Flame-Retardant Coatings in Upholstery Textiles: A Case Study Presenting Priority Research Gaps for Future Risk Assessments. The final report presents a case study of multiwalled carbon nanotubes (MWCNT) used in flame-retardant coatings applied to upholstery textiles. EPA states that the case study is organized around the comprehensive environmental assessment (CEA) framework, which structures available information pertaining to the product life cycle, environmental transport and fate, exposure-dose in receptors (i.e., humans, ecological populations, and the environment), and potential impacts in these receptors. EPA notes that the final report “is not a health, risk, or exposure assessment and as such does not draw conclusions about potential risks, or present an exhaustive review of the literature.” Instead, according to EPA, it presents the research priorities identified by experts to aid research planning. EPA states that the outcomes of these research efforts may subsequently inform long-term MWCNT assessments.
