On September 15, 2020, the European Food Safety Authority (EFSA) called for grant proposals on the use of new approach methodologies (NAM) for the hazard assessment of cellulose nanofibers. EFSA states that the use of cellulose at the nanoscale is increasing and requires an assessment. According to EFSA, the main concern is that the nanoscale

CDC Seeks Comment on Proposed NIOSH Exposure Assessment and Epidemiological Study of U.S. Workers
By Lynn L. Bergeson on
The Centers for Disease Control and Prevention (CDC) published a September 20, 2012, Federal Register notice seeking comment on a proposed National Institute for Occupational Safety and Health (NIOSH) exposure assessment and epidemiological study of U.S. workers exposed to carbon nanotubes (CNT) and carbon nanofibers (CNF). The notice states that the proposed research is a cross-sectional…
NIOSH Seeks Comment on Draft CIB Concerning Occupational Exposure to Carbon Nanotubes and Nanofibers
The National Institute for Occupational Safety and Health (NIOSH) released a draft Current Intelligence Bulletin (CIB) entitled Occupational Exposure to Carbon Nanotubes and Nanofibers, which recommends that, until results from research studies can fully elucidate the physicochemical properties of carbon nanotubes (CNT) and carbon nanofibers (CNF) that define their inhalation toxicity, employers should take…
