Understanding the Broad Class of Carbon Nanotubes and Nanofibers (CNT/F) Used or Produced in U.S. Facilities

  Engineered nanomaterials, such as carbon nanotubes and nanofibers (CNT/F), hold great promise for society by revolutionizing many industries with applications from medicine to manufactured composites. The properties that make them so promising may also have the potential to cause harm to people if inhaled. Understanding potential health effects, conducting field exposure studies, and developing good practices promotes safe handling and responsible development of products using these materials. The US-EU Nano Environmental, Health, and Safety communities issued a challenge to characterize nanomaterials better and to design research studies informed by exposure assessment with the same materials used in industry at
